The ultimate in convenience, the DM Vent Assembly is used with a “always connected” hose system and storage enclosure PN 5856. It allows the hose to readily extend or retract with dump valves closed. The kit comes with a Female Cam Loc pre-threaded with 3/4″ NPT hole to fit Air Release Valve (ARV); other required fittings, piping and elbow are all included. The ARV permits air flow in and out of the hose but seals up instantly in presence of liquid flow allowing completely normal drain operation. Waste Master Sewer Hose is not included.
