water pressure regulators

I have worn out 2 watts 263A units over the past 10 years of full time use. The brass at the point where the unit actually limits the pressure just eroded over time. You couldn't see it, but it quit limiting pressure. A rebuild kit didn't solve the problem since the main unit was worn not the rebuild kit parts. Two in 10 years? I can live with that and bought another one. Problem solved.
