Top 5 Common Causes for High Water Bills in Yolo County Homes
Before investing in new fixtures, you need to rule out the usual suspects. Here are the five most frequent culprits a Davis plumber encounters:
- Silent toilet leaks – A worn flapper can leak one gallon per minute, costing you $50 a month without a sound.
- Irrigation system faults – Broken sprinkler heads or cracked PVC lines in clay soil can waste hundreds of gallons overnight.
- Pressure reducing valve failure – Without a functioning PRV, Sacramento Valley’s 80-100 psi supply pressure can cause pipe joints to fail.
- Water heater scale buildup – Hard water deposits reduce efficiency by up to 30%, forcing your heater to run longer and use more cold water to compensate.

Professional Solutions: When to Call a Sacramento/Davis Plumber

Another critical upgrade is installing a new pressure-reducing valve set to 55-65 psi.

A licensed plumber can flush sediment buildup, replace the anode rod, and test the temperature-pressure relief valve to ensure your unit runs at peak efficiency. These steps alone can reduce your hot water energy costs by 15% and extend the life of the tank by years..
