How do you do a water pressure test. I know Tom mentioned it a couple times but I couln't find it. I am having a problem with my new dishwasher not cleaning (I had a plumber install the dishwasher from scratch). Knowing that the people before us didn't always do things right I want to make sure there is enough pressure (as long as it is easy to do). The other problem might be our water is too hard (according to manual). Anyway, if I am able to do this then I will know for rthe future for other things as wells. Thanks.;

Hey Duke,
House pressures will run between 40 and 50 PSI with the average 45 PSI.
There are many ways to test your homes water pressure. If you wish a permanent gage that will monitor your house pressure 24/7 then cut in a tee where the water service enters your home and bush the branch down to accept a 0 to 100 PSI gage.
However, for service calls I needed one that I could carry in my tool kit and still adapt to any house I walked into. I took a 1/2" copper to female thread adapter, soldered a short piece of 1/2" copper pipe on it with a 1/2" coupling that accepted a threaded bushing I could thread a gage on to.
I then had me a presure tester that would work any where I could get to a 1/2" male thread. All I had to do was unscrew the 1/2" shower head and replace it with my gage and turn on the shower. Result? Instant reading. I hope this helps you but if you have questions click on back. Tom
