How Do Sewers Get Clogged?

March 27th, 2015 by Michael Henderson

It’s not particularly pleasant to think about your home’s sewer line, but should you experience a back-up, or have trouble removing wastewater from your home, there is a likely chance your sewer line in Bryn Mawr, PA, is clogged. Any kind of sewer work requires a trained, licensed and certified expert, all qualifications that the plumbing professionals at Wm. Henderson Plumbing & Heating Inc., hold. First, let’s review the signs that can indicate your sewer has clogged:

  • Gurgling sounds from drains – are your drains gurgling every time you use them? This means there are unwanted air pockets in the pipe that are releasing air each time water passes through, which can indicate that a leak or crack has developed.
  • Slow drainage – if the majority of your drains are draining slowly, this is a good indication that there is a clog deep in the system.
  • Toilet won’t flush – if the sewer pipe is backed up from a clog, your toilets will no longer work.
  • Foul odors – breaks in a sewer line don’t just release dirty water, they also release an unmistakable odor.
  • Puddles in the yard – water released by a buried plumbing line, like your sewer line, will make its way to the surface, creating puddles in your yard.

So what are some of the causes of sewer clogging? Here are a few common ones:

  • Tree roots – tree roots are notorious for infiltrating sewer lines and/or crushing them, creating significant damage to the line.
  • FOG (fats, oils, grease) – FOG are some of the worst items to put in a drain as they cling, stick and solidify, creating a messy glop that when large enough, can create a major blockage.
  • Mud – dirt shouldn’t be present in your sewer pipes, but if it is, it won’t breakdown and wash away like other materials; instead, it settles to the bottom and creates a build-up of mud that can seriously restrict water flow.
  • Disposal of improper materials – some people treat their toilets like a garbage and the truth is your sewer line plumbing is designed to manage only human waste and toilet paper. When other items are consistently flushed down into the system, a blockage can develop.

When Is It Time to Call for Commercial Heating Repair in Wynnewood?

March 20th, 2015 by Michael Henderson

Indoor comfort is critical to the operation of your business, so it’s important to know when to call for commercial heating repair in Wynnewood. Problems with heating systems aren’t always overtly evident, so to help you decipher some of the signs, our commercial heating experts have put together a list for your reference:

High Heating Bills

Most businesses program their heating to help maintain costs. If you notice that your heating bills are suddenly skyrocketing but haven’t changed how you heat your business space, there is a good chance something is wrong with the system. Why? A system that operates with a malfunction tends to use more energy than a system that is operating normally, resulting in higher energy bills.

Abnormal Sounds

The operation of your commercial heating system should be pretty quiet; the components are typically located outside or in a closet or basement space, so all that is audible is the sound of the air moving through the vents. If you start hearing different noises, such as buzzing, banging, or anything else out of the ordinary, it’s time to call for help.


There should not be any kind of odor emanating from your commercial heating system. Should you smell something, it’s time for expert help to review the system.

Low/No Heat

The most obvious of signs, having no or low heat requires immediate help from an expert. There can be multiple reasons why your commercial space isn’t getting enough heat, ranging from motor issues to problems with the ductwork. Commercial heating systems can be long and complex, which is why it’s important to always call for expert commercial help.

Many buildings and commercial properties have on-sight building help, but being handy simply isn’t enough to correctly repair a commercial heating system.

Why It’s Important to Schedule Your Humidifier for Maintenance

March 13th, 2015 by Michael Henderson

It’s recommended that homes have a stable humidity level between 30%-50% year-round, but sometimes achieving this can be tough, especially during the winter months. Heating systems can dry out the air, particularly forced air systems, and it can be very hard to maintain a healthy humidity level indoors. A great tool that helps homeowners balance the air in their homes is a whole-home humidifier. These devices integrate seamlessly with HVAC systems, and you can install a thermostat that also has a humidistat, so you can set and program your humidifier right from your home’s thermostat. However, like your HVAC system, it’s important to maintain your humidifier on an annual basis. The indoor air quality experts at Wm. Henderson Plumbing & Heating Inc., have the expertise needed to properly perform maintenance on your humidifier, so if it’s been more than a year since your humidifier was last scheduled for work, call us today!

Reasons for Maintenance

As an electrical device, maintenance does a number of positive things:

  • Improves efficiency – your humidifier does a lot of work, and if it is carrying excess wear and tear, its efficiency may be compromised. Having a trained expert clean it can go a long way toward making your humidifier as efficient as possible.
  • Helps prevent repairs – humidifiers aren’t the most complicated devices, but that doesn’t mean they can’t break down. The thorough cleaning and inspection that your humidifier will go through during a maintenance appointment will help prevent future repairs as well as get you ahead of existing or developing problems.
  • Improves performance – as a water-based device, it isn’t unusual for humidifiers to become clogged or develop mold that can clog it. During a maintenance appointment, the filter will be changed if needed, removing any sediment or other particles that may be trapped in the filter.

You installed your whole-home humidifier for multiple reasons, and if your humidifier isn’t working as it should, you aren’t getting the benefits of owning one. Maintenance keeps your humidifier in good working order;

If it’s been more than 12 months since your humidifier has been reviewed, call Wm. Henderson Plumbing & Heating Inc., today.

What Is a Chimney Liner?

March 6th, 2015 by Michael Henderson

Many people have heard of chimney liners, but what they do and why it’s important to have them isn’t always so clear. Chimneys can easily become coated with creosote, soot and ash, especially if you use your fireplace regularly. There is no protection for the masonry inside your chimney and years of use create a level of wear and tear that can make your chimney vulnerable to problems, especially if you don’t have your chimney cleaned annually. While maintaining your chimney is important whether you have a liner or not, a stainless steel chimney liner for your Drexel home offers a level of protection and durability for your chimney that masonry alone can’t provide. The chimney experts at Wm. Henderson Plumbing & Heating Inc., have been specializing in chimney liner installation for almost 40 years, so if your chimney needs a liner, call us today!

What Is a Liner?

A chimney liner is a metal or clay pipe that is installed into your chimney from the top down to the bottom. The liner helps expel combustion byproducts while also protecting the inside of your chimney.

Reasons to Install a Chimney Liner

There are three main reasons to install a new chimney liner:

  • You have no chimney liner
  • Your current liner is old and/or damaged
  • Your chimney has damage
  • You are installing a new stove into your fireplace and a liner is required for safety and proper function

There are three categories that delineate the types of chimney liners available: light, high performance light and heavy. Any chimney liner you install should indicate that it meets UL (underwriter laboratories) testing standards, and if you are installing a liner for solid fuel stove going into your fireplace, it is required that the liner be insulated.

The main materials used for lining a chimney are stainless steel, aluminum and clay. Here at Wm. Henderson Plumbing & Heating Inc., we install both stainless steel and aluminum chimney liners.

Need a Chimney Liner?

Installing a new chimney liner is not a DIY kind of job for multiple reasons, including safety.

If you have concerns about your home’s chimney, call the experts at Wm. Henderson Plumbing & Heating Inc., today.

What Is Trenchless Technology?

March 5th, 2015 by Michael Henderson

One of the reasons homeowners cringe when they need sewer or water line work is the mess that has traditionally accompanied these kinds of plumbing jobs. Major plumbing pipes, like your sewer or water line, run underground, and reaching them from the surface requires digging long, deep trenches that can rip up an entire yard. But when you hire a professional who can perform trenchless technology, you won’t have to see the equivalent of an archeological dig at your home. Trenchless technology allows your plumbing experts to repair, re-line or even replace faulty, underground plumbing without digging down to reach the piping. How does this work? Let’s take a look.

How It Works

The first step your plumbing expert will take is to use visual aid equipment to see what’s happening inside the pipe. Even if you need replacement, the video will allow the plumber to pinpoint the exact areas that are failing inside the pipe. Once the problem or problems are ascertained, work can begin. There are a number of ways trenchless technology is used, including:

  • Sliplining
  • Pipe bursting
  • Shotcrete
  • Gunite
  • Cured-in-place-pipe (CIPP)
  • Grout-in-place-pipe
  • Mechanical spot repair

Using these methods, your underground plumbing can be repaired, re-lined or even replaced. One of the most common ways trenchless technology is used is to replace piping without digging, also known as pipe bursting. The way it works is that the new pipe is pushed through the existing pipe, which forces the existing pipe to fracture from the inside; the fragments from the old pipe are pushed outward and away from the new pipe.

Benefits of Using Trenchless Technology

The main benefit of using trenchless technology on your underground pipes is the avoidance of having trenches dug deep into your yard. But there are a few more worth noting:

  • Saves time – using trenchless technology allows your plumber to complete the work more quickly, which can save you money
  • Creates less mess – with trenchless technology, far less mess and waste is created
  • Vast majority of the work is done outside your property

It takes specialized training, tools and experience to be able to correctly use trenchless technology, and this is something you can count on from the plumbing experts at Wm. Henderson Plumbing & Heating Inc.

If your home in Wayne, PA could benefit from trenchless technology, call us today!

What Is a High Efficiency Air Filter?

February 27th, 2015 by Michael Henderson

Having good indoor air quality is important to your year-round, overall comfort. One way to help ensure that your indoor air quality is at the level you need and want it to be is by using a high efficiency air filter, also known as a HEPA filter, in your Springfield, PA, home. However, before installing any kind of HEPA filter into your HVAC system, it’s very important to consult with an indoor air quality expert. This is because the media in a HEPA filter can be so strong that it significantly reduces the air flow in your HVAC system, which can lead to operational problems. Wm. Henderson Plumbing & Heating Inc., has been providing indoor air quality services for almost 40 years, and our IAQ specialists can help you determine which HEPA filter is best for your home. Call us today!


MERV and HEPA are intertwined because MERV, which stands for minimum efficiency reporting value, tells consumers how effective a particular air filter is. The MERV scale runs from 1 to 20, and to qualify as a HEPA filter, the filter has to have a minimum MERV of 13 and these other qualifications:

  • The filter must be able to trap particles as small as 3 microns (human hair is typically 70-100 microns in size)
  • The filter must be tested according to US Military standard 282, and each tested filter must be individually certified and labeled with its test results
  • The filter must have a minimum efficiency rating of 99.97%


What Makes a HEPA Filter Different?

One of the main differences between HEPA mechanical filters and those that aren’t HEPA is the capture capability. HEPA filters are made to capture a great many particles, including some biological contaminants. This is because of how they are made, which brings us to a second difference between HEPA filters and non-HEPA filters. The media of HEPA filters is made with a glass-fiber type of paper that is highly effective at capturing particles. This paper is folded into small V-shaped pleats that are held firmly in place by aluminum separators between each pleat. Pleating makes it difficult for particles to continue passing through filter media, which is part of the reason why HEPA filters are so effective.

As mentioned above, HEPA filters should only be installed into your HVAC system after working with a qualified specialist. If you feel a high efficiency air filter in Springfield, PA is for you, call the indoor air quality experts at Wm. Henderson Plumbing & Heating Inc., today!

Signs Your Commercial Plumbing Needs Replacement

February 20th, 2015 by Michael Henderson

No business owner wants to think about having to replace plumbing, but as a business owner, you could be at serious risk of rendering your commercial space unusable if you don’t make needed plumbing replacement or repairs. Commercial plumbing systems are long and complex, so it’s important to hire experts with experience in commercial plumbing replacement for your Bryn Mawr business. Wm. Henderson Plumbing & Heating Inc., has been helping commercial customers with their plumbing needs since 1977, so if you are experiencing problems with your commercial plumbing, call us today!

Seeing the Signs

Here are some of the more common signs that you may need to replace the plumbing in your commercial space:

Discolored Water

Discolored water is often a sign that rust or excessive dirt is inside your piping. Typically discoloration will be brown or yellow, but any kind of discoloration means a problem has developed with your system and professional assistance is required.

Recurring or Multiple Leaks

If you have a leak that keeps coming back, or have been dealing with multiple leaks developing throughout your system, it’s time to have a professional assess the situation as it may be time to replace damaged piping.

Flaking or Dimpling of Metal Pipes

If you can see visible flaking or dimpling of your commercial space’s piping, there is excessive corrosion both in- and outside the piping. Excessive corrosion in any plumbing system is a serious problem and should be addressed immediately.

Development of Mold

Mold needs moisture to grow, so if you are seeing a lot of mold in a particular area or smelling a strong odor of mold, it is likely you have a leak on your hands; as such, you may need to replace the piping that is the origination of the leak, depending on the level of damage.

Water Pressure Problems

Water pressure is necessary for your plumbing to work, but if the pressure is too high or too low, a number of different types of problems can develop.

For your business space to be operable, it needs proper water function. If you are seeing the signs that it may be time for commercial plumbing replacement in Bryn Mawr, call the commercial plumbing experts you can count on: Wm. Henderson Plumbing & Heating Inc.

Some of the Unusual Movies Released for Valentine’s Day

February 14th, 2015 by Michael Henderson

Hollywood has always tried to match movies up to the seasons to draw droves of viewers to the theaters: October is packed with fright-offerings, while the winter holidays skew toward warm and pleasing family films (as well as Oscar hopefuls). Valentine’s Day falls in an odd spot when it comes to the movie release calendar, however, since February tends to be a slower time for the film industry. The studios are as likely to slot strange movies that don’t fit anywhere else in their annual schedules into the Valentine’s Day weekend as they are films with powerful romantic appeal.

So, while the second weekend of February has featured hugely successful romantic comedies like Hitch, The Wedding Singer, and (of course) Valentine’s Day, some truly weird choices have debuted in this weekend as well. And a few have even gone on to tremendous success despite the bizarre match with the holiday. Here are a couple of the odder Valentine’s Day movie releases:

  • Dracula (1931): Yes, this Halloween perennial and the start of Universal Studio’s Classic Monsters actually came out on Valentine’s Day! But perhaps this makes some sense, as the Dracula legend has often received a “doomed lover” approach in the many years since Bela Lugosi made the aristocratic vampire a screen icon.
  • The Silence of the Lambs (1991): Does any film seem less appropriate for Valentine’s Day than this unnerving and sometimes very violent psychological thriller? What’s even more astonishing than the film’s release date is that The Silence of the Lambs eventually nabbed the Oscar for Best Picture, an almost unheard of occurrence for a movie released so early in the year.
  • Daredevil (2003): This Marvel comic adaptation featuring Ben Affleck as a blind superhero does contain a romantic subplot, but the stronger connection to Valentine’s Day may just be that Daredevil wears a bright red costume.
  • A Good Day to Die Hard (2013): The least successful of the Die Hard film franchise, this is an excellent example of a studio dropping a film into a weekend where it doesn’t fit in the hopes that it works as counter-programming. (It didn’t.)
  • Wayne’s World (1992): Now here is an example of counter-programming that clicked with audiences. This comedy based on a Saturday Night Live sketch turned into one of that year’s biggest hits and spawned a sequel.

Whether you celebrate Valentine’s Day with a trip to the movie theater, or you have your own special plans, everyone here at WM Henderson Inc. hopes you and your loved ones have a wonderful weekend.

How Can Drain Cleaning Help Prevent Drain Repair in Ardmore?

February 5th, 2015 by Michael Henderson

While very few people truly enjoy cleaning the bathroom, you try to keep it as clean as possible for your guests and your own health and comfort. But while you may scrub the toilet, tub, and sinks diligently, there’s still one portion you may always miss, the drains. The drain opening may be shiny and spotless, but the inside of the drains in the bathroom and the kitchen may be coated with grease, “sludge,” and a bit of debris here and there. This increases the potential for drain clogs, which can inconvenience you in some major ways.

Some people attempt drain cleaning on their own as a form of clog removal or drain maintenance by pouring drain cleaning liquids down the drain. These are generally found at most hardware shops and even many grocery stores, but beware: these are some of the most toxic chemicals available for consumers to purchase in stores. Furthermore, they can actually damage the pipes, and most don’t clear clogs completely.

Professional drain cleaning uses zero toxic chemicals, so that no damage is accrued. Instead, they use any of several tools including drain augers that reach deep into the drain pipes and latch onto clogs in order to pull them up through the drain. Or, a technician may use a different attachment to break up clogs and send them into the sewer. In some cases, technicians may have to use high-pressure hoses to blast water into the pipes and remove any stuck-on sludge.

Some experts even use video pipes to inspect deep within the pipes and make sure that clogs are completely taken care of and that no further problems may lead to clogging in the future. Drain cleaning is a service which can vastly improve the condition of your plumbing system, to the point that you’re unlikely to run into any major drain clogs for the rest of the year.

Call Wm. Henderson Plumbing & Heating Inc. today!

When you schedule drain cleaning in Ardmore with one of our skilled professionals, you’ll get a thorough inspection and quality cleaning service with some of the best tools in the industry for maintaining drains.

Will Drain Cleaning Get Rid of Odors in My Drains?

January 30th, 2015 by Michael Henderson

It’s that unidentifiable smell around your sink. You clean the sink, wash dirty dishes, and yet, it hangs there. You finally bend down to take a good whiff, and realize that the smell permeating your nose is coming from your kitchen drain. What do you do now?

Smells from your drains are unpleasant but they aren’t permanent. Unless the source of the smell is from a sewer or septic problem, which most times it isn’t, the smells in your drain are caused by build-up that needs to be removed. So what’s the best way to remove the build-up? Schedule a drain cleaning appointment for your home in Newtown Square.

What Is Drain Cleaning?

Drain cleaning is the process a professional plumber uses to carefully remove build-up from the inside of your pipes. Typical build-up culprits are fats, oils and grease (FOG), soap scum, food particles and human hair, but many other things can get stuck in your drains. Food and FOG tend to create the most issues with foul smells because they can spoil, but slow-draining wastewater can cause odors, too. Removing build-up and thoroughly cleaning out the drain not only eliminates the odors, it has other benefits, too.

Benefits of Drain Cleaning

Here are some other benefits you can see from a professional drain cleaning:

  • Removal without damage – professionals know how to properly manage the tools used for drain cleaning, which ensures that they’ll get the gunk out of your drains without breaking anything.
  • No more slow drains – if you were seeing slow water drainage in a tub or sink, you won’t after a professional drain cleaning. Excessive build-up in your pipes can cause slow draining or clogging, so removing it allows your wastewater to flow freely.
  • Prevent clogs – removing build-up gets you ahead of potential clog development.
  • Helps maintain your plumbing – drain cleaning keeps your plumbing in good working order.

Wondering where those bad smells may be coming from? If you find they are from your drain, don’t wait for a clog;

Call Wm. Henderson Plumbing & Heating Inc. today and schedule a drain cleaning for your Newtown Square home.
