re: how difficult is it to do a pressure test

Need an air compressor and something like this. I made my own using one of these a gauge, and some air fittings to test both lines at the same time and blow out a water heater if needed. We PT and winterize a lot of vacant homes. If some of the idiots that work for me can do it then I imagine you can too.

You want to get the line to 35 PSI and see if it holds for at least an hour. If you have a gauge on your air compressor then you can buy this from Amazon and do it.

Yeah, this is not a good idea for the average DIY'er. Also unnecessary. Easier to just buy a cheap garden hose pressure gauge and use it to do a leak down test of the plumbing. Attach to hose bib, ensure it doesn't leak, make not of the water pressure then close the valve on the water meter. If something is leaking the pressure will drop steadily, if the issue is a leaking flapper valve then there will be a sudden drop to almost zero with the toilet valve opens to top off the tank. If the issue is a toilet fill valve then you simply just need to look in the tank and find one with the water level at the lip of the overflow tube, no need for any pressure test.

Bought a complete set up when I built my guest house to test the plumbing. Cost $30 here.
