Trouble shooting a Watts 3″ RP Mod 909
If you are a Backflow professional and are having problems with Watts 2.5″ and larger check valve assemblies, contact me to share information. It looks to me like the disc is short on material, see the photos below.
Watts customer service has suggested that we need to remove the seat and replace the seat O-ring. I will keep you posted.
I Checked the Seat, the O-ring, the epoxy Body. No Result. It Still appears to be the check valve in my humble opinion.
I will update the Blog as I get more Information.
