A huge thank you to Chris for doing a phenomenal job! He flushed our water heater, tested the water pressure, and thoroughly inspected the entire system to ensure everything was up to code and functioning properly. He also pointed out several improvements I could make to enhance our system, which I definitely plan to consider in the future. Chris patiently answered all my questions, provided valuable maintenance advice, and explained everything clearly and professionally. What impressed me most was his honesty, straightforward approach, and attention to detail. There were no surprises or hidden fees, just excellent service from start to finish! I highly recommend Chris to anyone looking for a knowledgeable, honest, and professional technician. Thank you again for the outstanding service!

Common Signs That Repair Is Needed

The most obvious sign of a problem is cold water coming out of your faucet or showerhead. But there are other things to watch out for that may indicate a need for repairs. We’ve outlined some of them below.

  • Rusty or Discolored Water: This can be a sign of a few different things. It may mean that you have sediment buildup at the bottom of your tank or that the anode rod is failing. It may also mean that your tank walls have started to rust.
  • You Hear Noises Coming from Your Unit: Sometimes, sediment buildup can cause popping sounds as bubbles form underneath and rise to the surface. Whistling sounds often relate to a valve problem.
  • You See Water Pooling: This can happen if there’s a problem with the pressure relief valve or the drain at the bottom. But it may also indicate a crack in your tank, which would mean it’s time to replace the unit.
  • The Pilot Light Won’t Stay On: This can be caused by problems with the thermocouple, which may be damaged or have too obstructing it. You may also have a problem with the control valve failing to deliver gas correctly

Nowadays, homes can be outfitted with a variety of different kinds of heaters. Some run on gas. Some are electric. There are tankless and tank options. Our team has familiarity and experience working with all these systems.
