Water Pressure Regulator Failure

Rude awakening this morning - rug in front of toilet was water-soaked. Checked water pressure regulator, Watts #H560, and it showed 90 lbs. pressure. The regulator that failed is about three years old. We previously had used an in-line regulator, but decided to upgrade to the Watts. Just never realized that failure of the Watts regulator would allow full line pressure through to the motorhome. The failure happened sometime between 1 a.m. and 8 a.m. and the toilet valve was the only place there was a leak. Found a new in-line regulator and installed it - disaster averted and problem solved.

After connecting the water and turning on the water heater the pressure might rise in the RV if you use no water. It is possible that the regulator didn't fail. The regulator has no way of bleeding off excess pressure downstream.

Failed
OR got jammed by sediment/debris.

That regulator is serviceable -- can be disassembled for cleaning and rebuilding if needed

I have same regulator......8 yrs old. Have had to clean a couple of times.
