Watts 009 M2 1 2nd Check Kit

This Watts 009 M2 1 2nd Check Kit is a repair kit designed for Watts Series 009 backflow preventers in M2 or 1 inch configurations. It provides the necessary internal components to restore proper check valve function. Professional plumbers and facility maintenance teams use it to maintain compliance with cross-connection control requirements. The kit arrives new and ready for installation.

Includes Check Assembly Cover O-Ring

The bundle supplies a complete check assembly and a cover O-ring matched to the Series 009 valve body. Replacing both parts together ensures a reliable seal and correct seating of the check mechanism. Silver-coloured thermoplastic components resist corrosion in potable water applications. No additional gaskets or hardware are included in this package.

Suits Series 009 M2 1 Inch Valves

This kit fits only Watts Series 009 units in M2 or 1 inch sizes; it will not work with other series, sizes or brands. Installers needing parts for different valve models or larger diameters should look elsewhere. The product carries a California Proposition 65 notice regarding reproductive harm. Buyers seeking a full valve replacement rather than an internal repair should consider a complete assembly.

Questions about this item

How often should the check assembly and cover O-ring in this second check valve repair kit be replaced?

Replace the check assembly and cover O-ring whenever the backflow preventer fails its annual test or shows leakage, as these are the only serviceable parts in the kit.

What is the first performance limit that appears when this repair kit is used continuously in a backflow preventer?

The first limit is debris or mineral buildup fouling the new check assembly, which stops it from sealing properly under sustained flow.

Does the thermoplastic check assembly in this kit generate noise or heat when the valve runs all day?

The thermoplastic check assembly operates silently and produces no measurable heat during continuous water flow.
