I need to install nrv for my home. There is 4" pvc pipe coming out of my bathroom into a inspection chamber, which is connected to an outlet pipe of 6" to the road drainage. Road Drains overflow during rain and water enters the bathroom. What type of nrv valve I should opt for. The depth of inspection chamber is only 1" about from the 4" pipe and 0" from 6" pipe. Dimension is 2"*2"*2" for the inspection chamber.

Sir any suitable type used for vertical piping? And how does dual plate NRV close itself as it is not against gravity ?
@gourisankarsamanta7670

Dual plate NRV is spring loaded. For vertical piping dual plate NRV can be used, if flow is upward.

Yes, NRV can be used inside a pit or chamber so that valve maintenance and gasket replacement will be possible.
