High water pressure can damage plumbing fixtures and water appliances, such as washers and dishwashers. Luckily, most homes with high water pressure have a pressure-reducing valve that lowers the water pressure at the mains. If the valve is faulty, it can expose your water fixtures to damage. Therefore, look out for these signs of a faulty pressure regulator valve and fix the valve to protect your plumbing fixtures. 

Leaking Faucets

A faulty pressure-reducing valve can fail to control the water pressure at the mains. Consequently, your faucets and appliances will receive high-pressure water. Over time, the high pressure exerts a force on the faucet's joints, gaskets, and other crucial components. The faucets will weaken, crack, and leak due to the pressure. If the faucet handles are leaking water when the faucet is turned off, check your water pressure. Besides repairing the faulty valve, you must also fix your damaged faucets. 

Low or Fluctuating Water Pressure

Pressure-reducing valves have a gauge that allows you to set the preferred pressure at the mains. If the valve becomes faulty, its calibrations can fail, causing it to lower the pressure beyond the preset psi. When this happens, you will experience low or fluctuating water pressure throughout the home. If you notice a significant loss of pressure when using multiple fixtures, you probably have a faulty pressure regulator valve. However, before drawing this conclusion, ensure there is no change in water pressure from the municipal council's supply.

Banging Sounds in the Walls

A faulty pressure-reducing valve may fail to regulate the pressure at the mains. As a result, the water entering your plumbing pipes will have high pressure too. As the water is pushed through the pipes quickly, it crashes around the walls of the pipes, causing a hammering or banging sound. Noisy pipes are not just annoying; they are also a sign of looming plumbing problems. High water pressure can loosen piping fittings, forcing you to tear down sections of the walls to refasten the pipes and pipe fittings. 

Plumbing Leaks

A faulty pressure-reducing valve can cause indoor and outdoor water leaks. A damaged valve will probably leak and soak the surrounding soil with water. Consequently, you will notice wet or sunken spots in your yard. High water pressure can also loosen pipe joints and damage pipe sealant, increasing the risk of leaks. Look out for water stains on the walls and ceiling, tricking noises in the walls, and musty odors. Also, inspect your pipes for leaks if your water bills have skyrocketed with no reasonable explanation. 

The most evident sign of a faulty pressure regulator valve is a fluctuation in water pressure. Contact your plumber for immediate plumbing repairs to prevent damage to your home and plumbing.
