No Hot Water


Hard water contains a lot of minerals and depending on how hard the water is also depends on how often you must replace the filters. A much better alternative is to have a water softener installed before your hot water heater and any other sorce of domestic water supplying your home. I have one and it works great. Just be advised that you will need to replace the salt crystals every couple of months depending on the time intervals you set the timer to. If you find that the water still remains soft after two months and your filters are not to badly clogged then you may try adding salt every three or four months and see if that solves your problem. You also have to remember that your also using the water for drinking cooking and bathing so softening your water supply is very important especially if you or anyone in your household ever had any kidney stones or kidney problems.

Good luck,

Marty

Our water keeps fluctuating between hot and cold. The hot water will not stay on. It lasts about 1 minute and then turns to cold. After about 2-3 minutes it will get hot again?


The inlet line to the water heater goes to the bottom of the water heater to prevent the cold incoming water from mixing with the heated water at the top. The tube going to the bottom can come loose.

Turn the water off and relieve the pressure by opening a faucet and remove the fitting where the water enters the heater. You can see if the pipe is still connected.
