You need to install a Amtrol Hot Water Heater expansion tank on your cold water line input to the heater. A plumber can do it, but you can also do it yourself if you have soldering experience. You need to solder a t fitting onto the cold water like that has a three quarter inch female thread. Then the expansion tank threads into that. Someone at a home store can help you and show you what it should look like. Ask them what you should pump the prtessure in the tank up to, becuz it depends on the water pressure in your area.

I got a new Rheem heater and it's complete garbage. No water pressure.

recently installed?

The three most common reasons for this happening to you are 1) a defective gas valve, 2) a rusty thermopile, and/or 3) the automatic shut-off not working as it should. So, the most common reason for many people having this problem stems from having a gas valve that is not working as it should. When your gas control valve is faulty, it will mean that your burner is not going to be igniting as it should-or at all. Something that worked for me one time was to turn the Temp all the way down then all the way to Max a couple of times..gradually. Why it worked I don't know. Got a couple more years out of it though. Good luck! Best to you.

there is pressure adjustment, just temp. water pressure in + water pressure out

I don't know for sure but look at page 117.... http://snowcrest.net/thriftysupply/pdf/RTG-Service-Manual-REV-2.pdf

Hi, From what I'm seeing this means that there is a bad part within your furnace and it needs to be replaced. It might be the thermostat. You might need to reach out to a local HVAC company to diagnose the issue in person. Thank you.
