I recently downsized into a condo, and sensing that the water pressure might be a bit high, today I bought a water pressure gauge from Home Despot, and got a reading of 90psi at an outside hose faucet. The condo was built in 1980, and I assume the pressure has been high ever since, although of course I don't know for sure.
I'm thinking about putting in a pressure regulator to bring it down to about 60psi, which would give me low-to-mid 50s at the second floor showers. Does anyone here have experience with these regulators? Is it possible that reducing the pressure after all these years might actually induce leaks? Are there any other downsides to these regulators?
I also need to replace a Moen 1200 cartridge that been there since 1980. I understand that getting the old one out after all this time can be quite an adventure, but what I haven't seen on Youtube is anyone using heat to help with that - a hair dryer, or even a propane torch. Seems like heat would help a lot. Has anyone here tried that?
