Water pressure in the Sunrise service area varies from 30 to 200 psi (pounds per square inch). Our objective is to provide water at desirable pressures, within technical and financial constraints. Water pressure at your home can affect the design, operation and longevity or irrigation components and water using appliances.
Common issues & potential solutions regarding water pressure:
Clogged aerator screens can impede flow. Problems with the mixer valve cartridge may be a problem with single handle fixtures. Also check for crimped water supply lines.
If only hot water has reduced pressure, the problem is likely at the water heater. check to make sure the shut off valve is completely open.
- Clogged filter media on in-home water filtration systems will reduce water pressure.
- If you live in an older home, mineral buildup inside pipes impedes water.
- Water line leaks can cause lower pressure.
- Check the master shut off valve. If it was shut off for repairs or other reasons, it might not have been fully re-opened.
- The pressure reducing valve may have failed in the closed position.
- The pressure reducing valve may have failed in the open position.
- Operational changes may be bringing water in from a different elevation than normal.
Thermal expansion occurs as water heaters increase the temperature of water and it expands. The expanding water is forced out of the water heater, pushing other water through the home, and into the water supply; carrying with it potential contaminants.
The resulting excess pressure may cause leaky faucets, bursts of water, or water being emitted from the relief valve of the hot water heater. Excessive pressure may result in damage to your water heater and/or plumbing system.
Excessive pressure may be eliminated by:
- Lowering the temperature setting on the water heater to 130° - 145°
- Installing a thermal expansion tank, which absorbs the increased pressure
Sunrise recommends consulting a licensed plumber to determine the appropriate solution for your home.
