Water pressure in Hesperia typically ranges from 40 - 125 psi; however, typical residential systems are designed to function best under a pressure of 40 - 60 psi. If the water pressure entering your home exceeds this level, you should install a pressure regulator on the line to reduce the pressure to an acceptable range. This protects your equipment and piping in your home from damage from excess force exerted by the water.
Symptoms of high pressure include "clanging" or "rattling" of pipes that occur when a faucet, dishwasher, or washing machine shuts off; water heater pressure relief valve malfunctions, and reoccurring leaks. The symptom of low pressure is typically a noticeable reduction of flow.
Note: Like all things mechanical, pressure regulators can and DO fail! The typical life span of a pressure regulator is 6 to 8 years. The higher the pressure that is being regulated, the shorter the life span of the regulator.
The first thing you should do is check with your neighbors. Is their pressure low too? If the answer is yes, the low pressure is most likely due to an occurrence within the District's infrastructure. Valve operations, peak water usage, pump starts and stops, changes in storage tank levels, power outages, piping failure, construction, and/or mechanical failures can cause pressure problems that can be neighborhood-specific. If this is the case, we'd appreciate hearing from you so we can advise you of the situation or dispatch immediate assistance.
If low pressure is occurring only on your property, it may be caused by any of the following:
- Water leak on the property
- Failure of regulator
- Mineral deposits inside pipes or hoses
- Plumbing modifications
- Simultaneous household appliance use
- Landscape irrigation scheduling
- Landscape valve and system design
- Faulty adjustment of the regulator
Should you decide to contact a plumber, the City recommends that you obtain multiple quotes from qualified plumbers with both a State Contractors License and City of Hesperia business license.
