The answer to 'lifespan of pressure regulator' is that a properly maintained pressure regulator can typically last 8-12 years. Pressure regulators are an essential component of a home's plumbing system, responsible for reducing the main water supply pressure to a safe level for the home's fixtures and appliances. Over time, the internal components of the regulator can wear down, leading to decreased performance or even complete failure.
To extend the lifespan of a pressure regulator, it's important to have it inspected and serviced every 2-3 years by a professional plumber. This allows them to check for any wear and tear, clean the internal components, and make adjustments as needed to ensure the regulator is functioning correctly. Proper maintenance can help a pressure regulator reach the upper end of its expected lifespan.
