Since 2009, Dierolf Plumbing & Water Treatment has been a fixture in East Coventry Township. We know that this area—stretching from the historic village of Parker Ford to the banks of the Schuylkill River—is one of the most diverse landscapes in Chester County. The company was founded by Mark Dierolf. He brings over 25 years of hands on industry experience to every job. Whether you live in a colonial era home near the Fricks Locks Historic District or a newer property near Ellis Woods Park, we understand the unique challenges of your local water.
East Coventry is a community where history meets modern living. Many homes in Parker Ford and along Route 724 rely on private wells that draw from complex aquifers. These wells often face a dual threat: natural mineral hardness from the ground and potential runoff from the surrounding agricultural lands. Meanwhile, homes closer to the river or in denser developments may be on public water that is safe but heavily chlorinated. We do not offer one size fits all solutions. We treat every home as a unique ecosystem. We analyze your specific water chemistry to provide a fix that keeps your family safe and your plumbing running smoothly.
Well Water: Nitrates and Bacteria
For our neighbors on private wells, specifically in the more rural pockets of the township, water quality is a serious concern. We frequently test for nitrates, which can enter the groundwater from fertilizer runoff or nearby septic systems. Nitrates are odorless and tasteless but can be harmful, especially to young children. We also monitor for bacteria. We recommend annual testing and often install ultraviolet (UV) disinfection systems. This technology creates a firewall against bacteria without adding chemicals to your drinking water. You can learn more about these invisible threats in our guide to demystifying water chemistry.
Hard Water and Plumbing Protection
Whether you are on a well or public water, hardness is a fact of life in East Coventry. The calcium and magnesium in our water cause scale buildup that destroys water heaters and clogs fixtures. If you are tired of scrubbing white residue off your shower doors or dealing with dry skin, we can help. We install high efficiency water softeners that remove these minerals. This protects your home’s infrastructure and provides the luxurious feel of soft water.
Modernizing Historic Plumbing
East Coventry is rich in history. Many properties here have plumbing systems that have been pieced together over generations. We specialize in navigating the unique challenges of older homes, from replacing corroded copper pipes to updating pressure tanks in tight stone basements. Our Licensed Master Plumbers have the expertise to bring your historic home’s plumbing into the 21st century without compromising its character.
We are proud to serve the East Coventry community. We love spending a sunny afternoon at Ellis Woods Park or taking a walk along the river at Towpath Park just as much as you do. You might see our trucks driving through Parker Ford on the way to a service call. We support the local landmarks that make this township special. Our goal is to ensure your water quality is worry free so you can focus on enjoying life in this beautiful part of Chester County. You can always check the EPA private well resources for more information on maintaining your system.

Common Questions from East Coventry Homeowners
Is well water safe in Parker Ford?
It can be, but it requires vigilance. Because of the mix of agriculture and older septic systems, we recommend testing your well annually for bacteria and nitrates. These contaminants are common in our area but can be easily treated with the right filtration.
How do I fix low water pressure?
Low pressure is often a sign of a failing well pump or a waterlogged pressure tank. We carry high quality replacement pumps and tanks on our trucks. We can diagnose the issue quickly and get your pressure back to where it should be.
My water leaves white spots on my dishes. Why?
That is a classic sign of hard water. The dissolved minerals in the water dry on your surfaces, leaving behind calcium deposits. A water softener will eliminate these spots and protect your dishwasher from scale damage.

⭐⭐⭐⭐⭐ “Efficient and clean”
“Moved to Gilbertsville from Lehigh Valley in March. Was time for water treatment. Like using local. Went with Dierolf because they had done most of the houses in our development. David and Bobby were fantastic. Had a softener and RO installed. They were efficient and clean. Talked me through everything and left behind plenty of reminders including two about making sure to use crystals in the softener tank. Think we found ourselves a plumber.”
