What locations should I look in to find the water pressure regulator for my home?
It is a townhouse in NY state, with crawlspace. My section is 8 units connected together.
So far I’ve found about 5-6 pipes traversing my crawlspace between units. One pipe enters into my crawlspace and promptly makes a turn towards the rear of my unit for the furnace room on my first floor.
I believe this is my main line and there is a shutoff in the furnace room for the whole unit.
I have an issue with a shower that goes all hot or cold as you turn the handle; it makes a banging/clunking sound when the water goes all hot or cold. Moen 1222 cartridge. Plumber felt the water pressure was too high; told me to call him back when I located the regulator.
