The answer to 'how long does pressure regulator last' is that a typical pressure regulator can last 8-15 years with proper maintenance and usage. Pressure regulators are an important component in your home's plumbing system, responsible for controlling the water pressure and ensuring it stays within a safe, optimal range. Over time, the internal components of the regulator can wear down, leading to fluctuations in water pressure or even complete failure.
To maximize the lifespan of your pressure regulator, it's important to have it inspected and serviced by a professional plumber every 2-3 years. They can check for any signs of wear and tear, clean the components, and make adjustments as needed to keep it functioning properly. Proper maintenance and care can help your pressure regulator reach the upper end of that 8-15 year lifespan.
