Low water flow from city supply
I have good water pressure at the inlet from the city supply at 80lb. When I turn on one tap the pressure dropped to 40-60lb. Each additional tap drops another 20lb+. The flow almost slow to a trickle especially the shower when I flush the toilet. I believe my problem is low flow from the city. Replace the supply line will cost $$$$.
Is it possible to use a pressurized 20 gal tank to hold some water for sudden demand? Do I need a one way valve to prevent back pressure to the city supply.
Help..
Low water flow from city supply
Thanks for the quick reply.
It is 3/4 in copper pipe coming into the house. 60% of the inhouse pipes are 3/4in. I think the pipe coming from the city supply has mineral deposits. The pressure is good but flow is slow. I don't know of a way to back flush it. That's why I am thinking of a pressure tank.
