Good evening,

For the past few months the hot water pressure in our home has been incredibly low. For the first few yrs we lived in this home both the hot & cold water had excellent pressure. Then for the past few months the hot water pressure has decreased dramatically-in ALL faucets/shower in the house. What could cause this? Do we need a new water heater?

Check for clogging in your hot-water line. Especially if there are filters installed in your system. If the temperature of your hot water has not changed you don't have to change your heater.

When was the last time the sediment was flushed out of the tanks drain valve?

What type of piping do you have Ferrous metal or non ferrous metal?

Did anyone try testing the T&P to see how the pressure is and if it is functioning properly?

Sometimes the heat sink installed can become blocked and in this case the system should be shut, then allowed to cool down and the unions if applicable opened and physically check to make sure the in let and out let are clear.

Some folks do install water heaters without the use of dielectric fittings and this can cause a loss of volume and then a pressure drop as the piping becomes corroded do to electrolytic action
