An apparatus for venting several plumbing pipes through existing roof openings made for existing ventilation systems, including turbine ventilators, roof ventilators, ridge ventilators and hip ventilators. The plumbing vent apparatus has two sides, a bottom and two removable end caps. End caps for use with a ridge ventilator or hip ventilator have slots for fitting around the ridge rafter. The apparatus is mounted in the roof opening made for the ventilation system, which is installed above it. When used with a ventilation system which has a ridge or hip rafter, the apparatus can be configured to have mounting flanges along the top of the sides for attachment to the roof decking, or can have mounting flanges along the slots on the end caps for attachment to the rafter. Each male adapter, which is inserted through an opening in the bottom of the apparatus, can hold the venting end of a PVC plumbing pipe. Removable covers are placed into unused openings. Methane and sewer gasses are vented from the plumbing vent apparatus and out through the roof ventilator.
