Tub spout leaking
Santa Cruz, CA 95062
Santa cruz, ca - recently, i completed a thorough flush of a tankless water heater. The process began with a detailed inspection to identify any signs of sediment buildup or mineral deposits. Using specialized tools, i carefully accessed the internal components of the water heater. I then employed a high-pressure water flush to remove accumulated debris, ensuring optimal performance and efficiency. Throughout the procedure, i maintained a meticulous approach to prevent any damage to the unit. Post-flush, i conducted a comprehensive test to confirm that the water heater was operating smoothly and efficiently. This maintenance not only extended the lifespan of the appliance but also ensured consistent hot water supply.

I saw a leak in the front of my house at 5 pm and it looked bad. I got an emergency plumber at my house and he fixed the main water connection to my house right away. All the other Plumbers I called would make me wait 2 days to a week to come by and given the leak I could not wait. I would use Duncan again with my next plumbing problem cause get it done!

I live in a house built in 1941. If you live in an old house it is a very good idea to find a plumber you can trust. Duncan Plumbing has been that company for me. This Saturday it was the hot water heater leaking from a valve on top of the hot water heater. By noon Sunday Duncan Plumbing was at my door (properly masked poor guy; it was almost 100 degrees) and discussed my options with me. He was pretty straightforward and I decided to replace the hot water heater instead of repairing. In a few hours he was done and cleaned up...that is one of the nice parts. I will call them again and again, because that is what happens when you live in a house built in 1941!
