Don't know if I'm posting in the right place here. I have a question about water pressure. Does anyone know what the safe or highest water pressure you can have in a house. What is the safe limit for water faucets & all the standard stuff like dish washers, washing machines, etc.
The main line I have is 3/4" & it branches off to 1/2" lines. I'm measuring 30 pounds at the outside hose connection that is closest to the main supply. My other hose connections which are 40 feet & 60 feet away from the main line are also measuring 30 pounds. There is a pressure regulating valve on the main line, but it has no valve handle or gauge on it. I'm told that regulator valves in general do not have a gauge or a valve handle on them. That sounds odd to me, but that's what everyone is telling me.
There's no way I can measure pressure on the water company's line from the meter to the house. The water company has told me that their line pressure should be around 70 pounds! They said they would come out and measure it for me if I suspect there is a problem with their line. At this point I think that the pressure regulator valve has gone bad or it is just set too low. Anyone have an opinion on this. I want to increase the pressure at the regulator valve, but I don't know what's safe for the branch plumbing & appliances, fixtures, etc. Also the pipes here are white-PVC.
The low water pressure is a pain. When the dishwasher is going or if one of the toilets are flushed, water flow goes down to a trickle at a sink faucet until the toilet fills or the dishwasher shuts off the water as it cycles. Thanks.
