Backflow preventer dripping
My irrigation system was installed in spring of 2002, and included a
RPZ type backflow preventer (Watts 009). This summer, it has
gradually developed a slow leak. It is dripping from the water outlet
on the bottom. It has never been exposed to freezing conditions.
Since it is only 2 years old, I can't imagine that the rubber seals
have failed already. What could cause this thing to fail so quick?
And can they be repaired?
Thanks,
John
