I have started having extremely low hot water pressure in all facets at home. The cold water is fine. I have experienced this in the past and it just returned to normal after about a week or so.

Is any plumbing work done lately?

First check you heater and see if the burner is running, and check the gas valve if it is set at right temperaure setting, 120 dgrees F is good setting, see the image below, if every thing is OK and you still have no hot water please get back to us, good luck.

I am sorry, my post is wrong this is for low temp. not pressure, I read it wrong, Thanks.

John

Please respond to my first statement, if any plumbing work is done in the house, Thanks.

How old is your water heater, and when was the last time that you flushed your water heater?

If you don't flush, (Not drain) your heater on a regular maintenance schedule you may have mineral build up that's clogging the pipes, let us know if you need know how to flush (drain) the water heater, Thanks.
