Questions about this item

Does the Watts 800 M2 vent kit generate noise, heat or draw power when it operates continuously?

The kit is a passive vacuum-breaker repair set with no motor or electronics, so it produces no noise, no heat and consumes no power during all-day operation.

Which existing Watts valve body must I already own for this 800 M2 vent kit to function?

You need a Watts Series 800 M2 vacuum breaker in the 1/2 to 1 in size range; the kit only contains the bonnet O-ring, float vent disc, vent float seal and spring for that specific body.

Will the bonnet O-ring and float vent disc from this kit fit older Watts vacuum breakers that are not Series 800 M2?

No, the components are manufactured for the Series 800 M2 1/2 to 1 in model only and are not interchangeable with other Watts series or sizes.
