Hi Experts!
I have an issue where the upstairs water pressure, specifically the shower, drops greatly (~in half) when a tap is openned downstairs. This is most noticed when the sprinklers come on or the garden hose is used. The biggest issues is that the water temp in the shower turns scalding when this happens.
I have a 1″ main from the city and a pressure regulator that feeds a 3/4″ line into the house. A 1/2″ line then feeds the entire upstairs.
Question -Can I resolve my issue by splitting the 1″ main into two 3/4″ lines, each with a separate regulator: one to feed the downstairs and one to feed the upstairs? The current pressure on the low side of the regulator is 75lbs. Not sure what the pressure is on the main side.
Thanks for any advice,
Allen.
