The water feed to the boiler has been on since you dug the hole and we have had no issues! Thanks again for all of your help on our kitchen remodel.


John Schramer of Schramer Plumbing has been an excellent plumbing partner for my organization. John is the best of what you look for in any contractor.  He is prompt, thorough in his work, and most importantly, he is honest. He treats everyone in my organization with respect when he visits our restaurants. Anytime we have an issue John always patiently explains what is happening in the most understandable terms possible and offers different types of solutions so that we can decide together what is the best way to fix the problem. We have been working with John for several years now. In that time he has helped us with jobs as small as a faucet repair and as large as digging up a parking lot and repairing a large pipe underground.

We have used John for several years and have always been happy with his service.  He is friendly, helpful, and always punctual. We love working with him.

We have used Schramer Plumbing for many years. Our house is over 70 years old and has some "unique" plumbing issues. John and his crew have always been able to quickly and efficiently fix all our plumbing issues. Additionally, John's knowledge of our boiler system is second to none. His knowledge and expertise in this area have kept us running without issues for many years. Always a pleasure to work with them.
