The Maxi-Vent is a SWR fitting is the preferred solution for venting the stack in the drainage system. This variation of the maxi-vent with the push-fit rubber connector creates ventilation in the drainage system that blocks the passage of foul smells resulting from loss of water seals in traps. Can be used in individual, branch, circuit, or stack vents.
USP: Maintains the right level of pressure within the drainage system by regulating air intake within trap seals. Eliminates roof penetrations and multi-level piping installation.
