Is my homes water pressure (90 psi) too high?
I had water pressure between 100-120 PSI for several years, and it made for louder plumbing, toilets that wouldn’t stop (with water bills much higher than they would otherwise be) and faucets that dripped/wore out faster than normal. Because of an ongoing drought in my area I decided earlier this year to become a responsible water user and had a reducing valve put in at the meter; it was about a $300 job but the reduction in my water bill was such that it will pay for itself by the end of the year. My water pressure is now 50-60 PSI, which is pretty standard. Anything above 80 is considered too high. You might want to leave the pressure guage connected for a couple of days to see if your 90 PSI is at the high or low end of the fluctuations that probably occur in your pressure.
