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.

Questions about this item

What Watts series must I already have installed for this 909 relief kit to fit?

This kit is designed for use with Watts Series 909 backflow preventers in the three-quarter to one-inch size range.

Will the included disc assembly and spring replace the original internals in my existing Series 909 valve?

Yes, the kit supplies a new disc assembly, spring, seat, seat O-ring, cover O-ring and lubricant to refresh the internal components of a Series 909 unit.

How can I confirm the relief valve is operating correctly after installing the kit?

After reassembly, pressurise the system and verify that the relief port discharges at the set pressure without leakage from the cover or seat O-rings.
