On the long week end in August our hot water tank was leaking. A technician, CLINT, came out and assessed the problem. The tank was 10 years old, and badly rusted. Clint brought a knew heater, did the install, and disposed of the old one. He is an extremely nice young man, very efficient and tidy, left no mess. Highly recommend Knight Plumbing.

New Water Tank Installation

Eventually your water heater will need to be replaced. We install a variety of makes and models, from traditional tanks to the latest tankless models that save money on your energy bills. Let one of our certified technicians recommend the right solution for you based on your budget, hot water requirements and priorities.

If you need a traditional hot water tank, we install tanks from trusted brands like:

  • Bradford White
  • John Wood
  • Rheem

We can also install other models on request. Our sales process is friendly and there is no pressure. In fact, our quotes stay valid for 30 days, so you have plenty of time to decide.

Maintenance Services

Water heaters are one of those machines that we take for granted – until they stop working.

Having maintenance performed every 1 – 2 years will not only dramatically extend the life of your water heater, but it will help it perform much more efficiently as well. It’s easy to add to your fall home maintenance checklist.

Did You Know? Water Heaters Lose 30% – 40% Efficiency Over 5 Years Due To Hard Water

Our technicians will not only check all of the components for proper function, but will treat your tank for calcium buildup that coats parts, interferes with heat transfer, and forces your tank to work harder.

Water Softeners Help

Having a water softener like Water Hound installed will help keep hard scale build up from forming. Ask your Knight technician if this is the right solution for you.
