Watts 909 Relief Kit

The Watts 909 kit is a maintenance package for Watts Series 909 backflow preventers sized 3/4 to 1 inch. It bundles the cover O-ring, disc assembly, seat, seat O-ring, spring and lubricant in one box. Plumbers and facility managers use it to restore proper sealing during scheduled rebuilds. The kit simplifies parts sourcing for this specific valve series.

Suited for Series 909 rebuilds

This kit fits only Watts Series 909 devices in the 3/4 to 1 inch range. It will not work on other Watts series, different brands or larger valve sizes. Buyers servicing other models must source the correct manufacturer kit. The included lubricant eases reassembly of the supplied components.

California Proposition 65 notice

The product carries a California Proposition 65 warning for a chemical known to cause birth defects or other reproductive harm. Installers should follow safe-handling practices and wear appropriate protection during service. The restriction list for regulated states is currently empty. This notice is the decisive compliance detail for specifiers.
