Questions & Answers

Is the pressure relief valve port above the hot valve (as the picture indicates) or on the side of the actual valve?

The picture is what I want. It has the pressure relief valve on a T above the valve instead of being built into the side of the valve. Above the valve allows the pressure relief valve to be positioned other than straight out the side of the valve, opposite of the handle. I don' t want to order this one (the one in the picture) to get the other type.
Asked by: SteveM
In the picture, the part of the pressure relief valve that is down is where the threads are that screw into the hot service valve. So, the whole to the left is where you would attache a pipe to insure there is no splatter should the valve open, or when you do your annual valve test. Regretfully, in the hot val in this picture, you cannot see where the pressure relief valve threads in, but it is there behind the red knob.

What's so special about these? Why not just use a regular on/off valve like in the pics of the Rheem 8.4 GPM tankless?

Rheem 8.4 GPM Natural Gas Mid Efficiency Indoor Tankless Gas Water Heater
Asked by: Gggggggggggg
The tankl;ess water heaters need to be isolated from the water system to be periodically de scaled by flushing a cleaner or vinegar through the system. This helps keep up the efficient heat transfer to the water. So these valve have 2 ball valves each, one to shut off the house water and the other to open where a hose is attached to pump descaler through. Also included is a pressure valve which is necessary for all hot water systems, tank or tank less.

The only problem I have is they leak where attached. I have put as many as 5 wraps of tape around the threads, but I strill get a drip. I brass brushed the threads on the second application with the same tape, but a drop appears with every use. However, the valves perform as expected.

Rated 5 out of 5 by from I had a Rheem Tankless water heater installed years ago... I had a Rheem Tankless water heater installed years ago and had not cleaned out the unit. I was under the impression I had these bypass valves already installed but to my surprise the plumber did not install as requested. Good news is they had installed shutoff valves with unions on 1 side. however the other side was soldered on. I decided to leave the existing ball valves on and put these bypass valves behind them. Installation was fairly smooth. I already had a blow off valve installed but since I did not have a 3/4" plug to seal the blow off valve female connection, I just put it on anyway. Install took about 10min/pc not including the 30min of moving and removing other existing pieces. I ran the cleanout process and it went as expected, letting vinegar run through the system for about 1hr. Not related to this but more related to cleanout. you should remove the built in filter on the water heater since the recirculating pump clogged that filter. So either keep the filter in and do a clean out every 10min or remove and then make sure you flush the system with clean water afterwards.
