Low presure on hot water
Posted by Don on November 04, 2001 at 01:09:38:
Decided to replace a two leaky valves and pipe (hot and cold)in the basement which required me to shut off the water supply. All the lines in the house were drained prior to this work. Placed everything back together and turned on the water supply. A lot of air came out through the pipes as I turned on the water. Cold water works great through out the house but I have not water pressure on the hot water. After leaving the hot water off for an hour I go back to a faucet to check if the pressure is there, and nothing. Some pressure at first then it turns to a dribble. I can feel heat on the water heater output pipes. I have a potable water expansion tank on the water heater if this means anything. One additional item. When I turned up the water heater temperature, it kicked on but made a lot of gurgling sounds so I lowered it back to the normal setting.
