[This review was collected as part of a promotion.] When I bought my house the toilet downstairs wasn't vented properly. My water would “syphon” and ended up costing me extra money on my bill. A plumber buddy suggested one of these vents , and it solved my problem immediately. Thanks to oatey's in line vent we do not have a problem anymore!
