Just put a new hot water heater 80 gallons and now we have no water pressure. What should we do?

Hi Marlene,

I need a few more details. Low pressure throughout the house or just certain fixtures? Does this affect the hot and cold or just the hot? If certain fixtures I'll need the name and type of faucet affected. I'll wait on your reply. Tom
