Thanks!

I had already seen that forum and your link... and in fact, the WPR in the how-to-instructions, looks exactly like the one I have.

I guess my question, is more about PLUMBING... and to learn that, I guess I will need to take some classes, thanks.

80 PSI would be way to high for internal piping which is why the house has a pressure reducer in the first place.... To ensure water pressure through the entire system, water is delivered often at much higher PSI than a typical home system can handle.. you solve it with a Pressure Reducer.

Generally replacing them is simple.. turn off the water supply, remove the old one and install the new one. Usually requires nothing more than a wrench or two and some teflon tape.
