"When a gas, tank water heater is installed, how is the pressure checked?" House pressure can be checked several ways. If you're on a well the pump will have a pressure gage. If you're on a meter then several methods can be used. Call the water department and ask what the pressure is out in the main, that will be the pressure that enters your house. If you wish to check the the water heater tank pressure you can cut in a pressure gage at the hot water outlet or tee out from the T&P valve opening and install the gage in the branch of the tee. I made up a "test gage" I took on service calls. I took a 0 to 100 PSI gage and Screwed on a 1/2 X 1/4" reducing coupling. This left me with a 1/2" female threaded end on the gage that I could then take and screw into a shower arm after I removed the shower head. When I opened the tub valve and diverted the water to the shower I had a reading on the house pressure. Hope this helps and have a great weekend. Tom
