I understand that having high water pressure results in higher water bills, banging pipes and appliance breakdowns. However, there is a huge difference in comfort when using faucets and showers at 120psi as oppose to 50psi especially when multiple showers, faucets or toilets are in use at the same time.
Our house has static water pressure of 120psi but when I adjust our pressure reducer valve to make it 50psi, the pressure is way too low and aggrevating when multiples are in use. I have tried it at 80psi and still a little aggrevating. Our house pipes do not bang and our appliances work fine. So, is it OK for me to leave it at 120psi? Our water heater has an expansion tank that is pre-charged at 70psi. Is it true that you should not go more than 80psi. What problems may occur by pre-charging so high?
Please advise. Thank you!
