I live in an 85 year old house that has a hot water boiler and radiators. I also have terrible water hammer when I use my LG washing machine. I tried using water arrester devices on the back of the washer, but they didn't work. Now I see that they should only be used with water pressure under 60psi. My water pressure is 90psi. If I put in a water pressure reducer for the whole house will I have enough pressure in my radiators to heat a three story house? Thanks for any help.
