- Water Pressure
Water pressure within SAWS' service area can range from 35 to 175 pounds. High water pressure can be controlled by a pressure-reducing valve (PRV) installed on the property owner's side of the water meter. If you already have a pressure-reducing valve, it may need to be adjusted or serviced. Recommended water pressure, especially if you have a water softener or a sprinkler system, is 80 pounds.
Is the problem at every faucet?
If not, you may have a clogged aerator. Check the screens for rust or other particles that may be restricting flow. Clean and/or replace the aerator. In single-handle fixtures, the trouble could also be in the mixer valve cartridge of the fixture, the water supply line may be crimped or the water supply valve may be partially closed.
Is the pressure the same at both hot and cold fixtures?
If only hot water, the problem could be with your water heater. Check the shut-off valve near the water heater to make sure it is not closed or partially closed.
Do you have a water softener?
If so, put the softener on bypass and see if the pressure increases. If this increases your pressure, the problem is probably in the water softener.
Do you have a pressure-reducing valve (PRV) on your property?
These are usually located on the property owner's side of the water meter. If you do, it may need to be adjusted or serviced.
Is your customer valve fully open?
These are usually located on the property owner's side of the water meter. This is the valve that allows you to turn off water to your house for repairs or other purposes.
Low pressure can also be caused by a water leak somewhere on your property. See our Checking for Leaks information.
