"I had just purchased a townhome with 4 bathrooms and they are all the original toilets from the year it was built, 1993. Every unit was operating fine to my knowledge except for one that would keep running. Shane came right at 8am and in about 35 minutes went to every toilet, tested it for any possible leaks, and noticed that the water level adjuster was not set right. I mentioned to him that the flush on every toilet seemed very "weak" and that was right away what he looked at and showed me, that the water level was set too low, so the tank was not filling to the proper level to give the right amount of a "flush."
Shane also took the time to show me a very easy fix on the toilet that I was complaining about running, and it was that the chain was getting stuck in the flapper valve, so that was a simple fix. What I respected and appreciated the most from Shane was his professionalism, and his willingness to show and explain to me everything he was doing so I could learn myself. A true professional and he was very honest about how much he takes pride in his work (and it shows!).
Thank you very much Mahon Plumbing and Shane, and once again Angies List for providing me another great experience/referral. I will also say that the rep I spoke to over the phone handling my initial call was extremely nice as well, not your typical secretary that takes a name and number. Was very nice and professional as well.
So for $105 and about 35 minutes of work, I got four toilets tested which all came out OK, and "fixed" for the weak flush issue, and a little bit of plumbing 101!

"Jeff Matthews of Precision Plumber did excellent work. He was friendly and professional. He coordinated his job with other workers and left the worksite clean. He was efficient and stayed late to complete the work. Very professional. Knew what he was doing. I would definitely use him again for future work. The tankless gas hot water heater works great!

"Easy to get an appointment and readily took care of installing 10 new smoke detectors. Wore a mask and was friendly and professional. Would hire again. Time of arrival delayed due to vehicle issues (which I know you can't plan for) so service was not at the time I had planned but I made it work. Promptly notified me of the delay and worked with my schedule for later that same day. I would use again."

"Paul and associates did a terrific job. The installation went very well. The unit used was not the typical unit because our house I'd so large. Paul utilized a hot water distributor from our old hot water heater. We now have instant hot water all over the house.
I will use Surfside in the future!

"EXCELLENT PROFESSIONAL SERVICE!  Called them cold on a Sunday night from my DC home to repair many shingle caps that had blown off the peak of our roof of our townhome in OC- I could see daylight from the attic and the insulation was wet.  They were on my roof Monday morning, in the rain, fixing it completely.  They took before and after photos on the roof so I could see exactly what they had done. They also replaced a cracked vent pipe boot. 
Very easy to deal with, good communications, knowledgeable and professional.

FAQs for water heater repair or service projects in Rehobeth, MD

Warning signs include fluctuating water temperatures, a pilot light that repeatedly goes out, unusual noises from the tank, or complete heating failure. You might also detect a rotten egg smell, indicating a potential gas leak, or notice water that never reaches the proper temperature. If your water heater is over eight years old and displaying these symptoms, the gas valve is a likely culprit. Professional inspection is recommended, especially if gas odors are present.

Water heater gas valves are not universally interchangeable. Each valve must match your specific water heater's make, model, and specifications. Important compatibility factors include gas type (natural gas vs. propane), BTU rating, connection types, and physical dimensions. Using an incorrect valve can result in poor performance, premature failure, or dangerous gas leaks. Always consult your water heater's documentation or a professional plumber to identify the appropriate replacement valve for your unit.
