Hi everyone obviously I am new here and need some help. Yesterday I installed a electric water heater. Now I can only get hot water from the sink in the bedroom bath when all the hot faucets in the house are on. The bedroom bath is closest to the heater, if no faucets are on the hot water comes out luke warm then cold.he main bath and kitchen hot only come out cold. The flex hose coming out of the tank is warm but any piping after the flex hose isn't. Thank you for any respones
