Hello,

We just had a new water heater installed yesterday and the water pressure seems to be reduced (probably 85-90%) of the prior level, through out the entire house. Our old water heater started to leak yesterday AM, had the new one installed that afternoon (40 gallon, 9 year wty, gas: GE model # PG40T09AVH00 purchased and installed by Home Depot). The inlet valve above the tank is open all the way, the inlet to the house in open all the way also).

Not sure why this would be, not very mechanically inclined...

Help and Thanks! Jack

Since you had HD do the install you should call them back immediately and ask them to diagnois what THEY did wrong. Did you have a new PRV installed (pressure reducing valve)? Did the pressure drop for hot and cold? Close the house main counting the # of turns required to close it. Reopen the house main, same number of turns?

Thanks. Is the PRV the valve above the heater that controls the water intake to the unit? I don't think that was replaced, the house and the old unit are about 10 years old. Both cold and hot water was reduced.

To clarify, the house main, are you referring to the water meter valve or the unit near the house? The main at the house in on the hose bib where the water enters the house and we have a simple on/off lever which is all the way open. I have no clue where to look at the water meter, the city installed an remote electronic sensor for meter reading...

I'd still call HD back. The PRV is usually installed just after the meter, the one you can't find. Most water lines enter the home below grade in the front of the house so look along the street side of your basement. If it's a finished basement there may be a trap door or something covering the main, it should never be sealed up so you can't get to it.

Thanks again! I will call HD back and get them back out. I will look on the main also, it is in front of the house, but I am not certain which knob controls the water flow into the home. I would assume they turned the water supply off at the hose bib rather than the meter while replacing the unit, but...

Thanks again and take care.

If you were a bit unsure I think HD probably was too. I'd check both shut offs to insure both are fully opened. Some old valves take 10 full rotations to open but a modern globe is only a 1/4 turn.

Thanks again for the help.
