Pressure Regulators
A pressure regulator protects your home by keeping incoming water pressure at a safe, controlled level. Allentown and many surrounding Lehigh Valley communities often experience pressure spikes caused by municipal changes, hydrant flushing, or nearby commercial developments. We install, repair, and replace pressure regulators to keep your home safe and your water flow consistent.
When a Pressure Regulator Is Required
A regulator is needed any time the city supply pressure is too high for residential plumbing. Many neighborhoods regularly reach pressures well above what fixtures and valves are designed to handle. Homes with updated plumbing, tankless water heaters, or multiple floors also benefit from a properly tuned regulator to prevent stress on the system.
What Causes Regulators to Fail
Over time, internal springs and diaphragms wear out. Mineral buildup, corrosion, and sudden pressure surges can also damage the internal components. Older regulators tend to stick open, stick closed, or drift out of the proper pressure range, creating inconsistent or unsafe water levels.
Symptoms of a Failing Pressure Regulator
Common signs include noticeably high water pressure, loud banging or vibrating pipes, dripping faucets, toilets that run constantly, or appliances that start to leak. You may also notice hoses, supply lines, or washing machine lines bursting more easily. Any unusual pressure-related noise is a strong warning that the regulator may be failing.
Maintenance Recommendations
Pressure regulators should be tested every few years to confirm they are keeping pressure within the proper range. A simple pressure gauge test at an outside spigot can reveal early issues. Regular inspection helps prevent hidden damage and allows us to replace the regulator before it causes leaks or appliance failure. When replacement is needed, we install durable, high-quality units built for long-term performance.
