Have You Asked Yourself Lately

Is Your Water Clean?

Tap water may contain chemicals, minerals, and contaminants that affect its taste and smell, making it less refreshing. Investing in a reverse osmosis water filtration system can eliminate these impurities and provide the freshest, cleanest water possible.

What’s Wrong with My Water?

Did you know that various unseen contaminants can potentially exist in your water, ranging from microscopic bacteria to invisible, harmful chemicals? Consuming such water might lead to a range of concerns.

At best, you might experience mild stomach discomfort or perhaps spend a little extra quality time with your favorite bathroom fixture. However, in more severe cases, these contaminants can contribute to long-term health issues like weakened immune systems, developmental problems, or even cancer. It’s safe to say that’s not the ideal formula for a healthy life.

Lately, there’s been growing concern about “forever chemicals” finding their way into drinking water sources nationwide. With incidents like train derailments spilling unknown substances into our waterways, it’s becoming increasingly challenging to be confident about the quality of our tap water.

What is an RO Drinking Water System?

A reverse osmosis (RO) drinking water system is an advanced solution that utilizes scientific principles to significantly improve the taste and quality of your tap water. By employing a semi-permeable membrane, RO systems effectively remove impurities from water. This membrane serves as a selective barrier, permitting water molecules to pass through while capturing larger particles such as minerals, chemicals, and bacteria.

Don’t worry about missing those “healthy minerals” in your diet from your water, you can’t drink enough water to actually see any health benefits.

Dierolf Plumbing & Water Treatment have systems with filters in addition to the semi-permeable membrane. Things like sediment and chlorine can be filtered out even before hitting the membrane, allowing the membrane to focus on all the smaller things that exist in the water.

The end result is water that’s so pure, you’ll swear it came from the purest of mountain springs. Use it for drinking, making coffee and in all your cooking!

Called them in the morning to schedule a plumber to come out to look at a leaky pipe. They were out within an hour, and it was fixed in about 2 hours. Communication was very impressive, everyone has been super nice and professional. Would highly recommend to everyone. Lukasz was the gentleman who came out and Kelly was who I spoke to on the phone.

We are very pleased with our decision to use Dierolf Plumbing for our whole house softener system. Not only were they competitive in pricing, but did an amazing job installing the system, explained how to use it and walked us through exactly what the system does. If you are on the fence about who to use, choose Dierolf Plumbing.

Dierolf has been super helpful to me since i purchased my home in 2018. I go to Mark and his team for all my plumbing questions and needs. Their service is always prompt and I have always had very professional encounters with every team member. Most recently I had to have my water heater replaced, Matt W. Gave me a number of options and was very communicative about scheduling as well. He and Lukasz were on time and completed the replacement quickly and efficiently. They thoroughly cleaned up the mess from the old water heater leak as well. All in all, it was another great experience with these guys.
