How can we help?


A backflow preventer is a required device for many of our commercial customers. In the event your backflow preventer breaks, we can guide you through the process to replace it. Designs for a new system are put together by engineers and submitted to the Water Department for approval. From there, the Water Department will approve one design. When you work with us, you can rest assured that our testing and installs are done quickly, efficiently, and reasonably.

Backflow Testing

If you currently have a backflow preventer, you should know that many municipalities require that it be tested yearly. T-Mark Plumbing, Heating, Cooling & Electric‘s Rapid Rooter Services can offer you a yearly reminder and file all your necessary paperwork to make this process as seamless for you as possible.

What our customer are saying...

Bud Shalkowski

Gary and John were awesome. Helped fix a collapsed cast iron pipe situation to entire new pvc system in the basement and sump pump as well… they were unbelievably helpful and I am appreciative of everything they did.


Jon Stachura was totally professional, respectful and congenial. He was actually available two hours earlier than expected. He quickly diagnosed the leak problem and offered best and worst case solutions for repair. Jon was mindful of the customers property. While he was initially expected to arrive between 12 & 2, he actually completed the job by 12:15pm. The job was not simple. It involved Jon opening a wall and removing a 125 year old section of iron plumbing stack and replacing with pvc pipe. Very pleased with his work. Thank you Jon and TMark!!!

Seth was courteous, professional and very knowledgeable when it came to my plumbing issues. He took care of the problem and I haven’t had any issues with plumbing since. I have used T-Mark several other times and all the staff does outstanding work. Thanks

Michelle Wing

I have had a nightmare of a time with the plumbing in the house I moved into a year ago. T Mark sent Seth out quickly, he was fast, professional, explained everything in detail, and was very understanding when I was very stressed. It’s very easy and efficient to schedule, company is great with communication, it was refreshing to be treated respectfully, would absolutely recommend and will use in the future.
