How to Clean a Plumbing Pressure Regulator

Water pressure regulators are installed in almost all homes. These bell-shaped devices regulate the amount of water pressure that is released from the main water supply line to the rest of the plumbing in your home. A regulator is made out of brass, which resists corrosion and is a generally durable material that many plumbing fixtures are made out of. However, brass may tarnish over time. It's possible to clean the regulator to restore its original brass shine.
