: : Terry- : : I recently discovered that my 22 year old custom home does not have a pressure regulator. The pressure at the hose bib is 105 pounds, and in the second story bathrooms 85 pounds. : : In preparation for the installation of a pressure regulator, I discovered that the main water line connects to a 3/4" copper line that runs for approximately 5 feet and then enlarges to a 1" copper line when entering the house. I am trying to determine if it is necessary to replace the 3/4" line. Does the reduction to 3/4" for a distance of 5 feet alter the water flow to the extent that replacement is necessary?? My house has 5 bathrooms. : : Thanks for your help. : : Evan : Evan, : That short distance of 3/4" should have much affect at that water pressure. : Most meters are 3/4" anyway. It's when more distance is added that the friction starts to build up. : Your pressure reducer is in the home and is a 1"? : You will need to install an expansion tank also. : Terry Love Terry why an expansion tank? I see several of your posters also recommending them. We do not have them in Kansas and have up to 120 lb water. LonnythePlumber

Terry why an expansion tank? I see several of your posters also recommending them. We do not have them in Kansas and have up to 120 lb water.
