Please help! We have a brand new AO Smith 50 gal. water heater in a 25 year old house. Within 5 weeks it began to leak, was replaced 5 days ago, with the advice to replace the pressure regulator or it could happen again with the present one.
The pressure regulator has now been replaced and we are getting little to no hot water in ANY of the faucets throughout the house.
We have been advised that this could be caused by a slab leak, but this is this the typical symptom of a slab leak?
Any ideas? We are not HANDY AND MUST RELY ON "PROS". Thanks!

potential bad, maybe good, news
the old regulator MAY have been set very very high to compensate for inadequate/corroded piping
.... no quick fix ... need a pro
the new regulator may be set too low ... recomend about 60psi ... if you have no gage you can purchase one that screws on to a hose bibb thread

By "little or no hot water", do you mean there is NO water flow, or the water flows but is not hot? Those are two different conditions with different causes. The regulator did NOT cause the first heater to go bad, it was just a bad heater.

it could be a slab leak but as long as there are no faucets leaking you can see that by looking at the meter.
you would have to have dangerously high pressure for that valve to have caused a leak on a new heater
you sure they turned the valve to the heater on after replacing it? or that it actually opened if it is a gate valve?

The heater is tested to 300 psi, and the T&P valve releases at 150 psi, therefore it could NEVER happen.

unless the t&p was bad

At 300 psi, it would have fixed itself, OR one or more faucet/toilet supply lines would have ruptured. IT was not a "pressure problem" that broke the heater's tank.

If it's "no hot water" I hate to ask... Is it turned on? Is the exit pipe hot?

To HIM, "no hot water" is obvious, to us it is ambiguous.
