Cheater vents, the ugly truth Here are two photos of the cheater vents I found in buildings on recent inspections. The first photo is of the chrome model and it was in a commercial building North of Orillia in the Muskoka area. The second photo is a little harder to see with the white wire partially in front of it where it was installed well under the kitchen sink in a log home I inspected not far from Gravenhurst. In both the above instances the vent unit itself is not CSA approved for use in residential or commercial applications. They normally sell for 7 to 1. The packaging states quite clearly for use in recreational vehicles only. They are meant to be used in trailers and camper units. All cheater vents are draw vents but not all draw vents are cheater vents These type units are referred to as draw vents and there are some draw vents available on the market from plumbing wholesalers costing from thirty to fifty dollars that are CSA approved and are approved for use in limited circumstances under the plumbing codes. It's an economy thing and a very bad choice. These 7 - 1. 2 dollar venting units will fail, when they do it may only stink up the building but it may also be much worse; it could be the cause of an explosion or fire or even the loss of a life. How draw vents work In simple terms draw vents work with a spring that holds a flap closed under normal conditions. When a flow of water goes past the short pipe the vent is mounted on, the suction opens the flap and lets water continue to flow past because it has equal pressure on both sides, gravity is pushing the water down the pipe. When the water stops flowing past, the suction stops and the spring forces the flap closed stopping sewer gases from coming back up the fixture and into the home but filling the length of pipe from trap to vent. The vent pipe then allows sewer gasses to flow up the vent pipe and out of the home into the open air above the roof. Note the difference between the two. One is open to the air the other has the sewer gasses filling the pipe and blocked from escaping at all. Old plumber talks about an automatic air vent. Venting plumbing fixtures.
