“Works well, but the installation instructions should specify it needs a 2" pipe.”
“I sampled The Oatley Air Admittance Valve Kit #: 39239. It is a one-way valve designated to allow air to enter the plumbing drainage system.”
“This works awesome if you're installing a dishwasher or venting under a counter out of sight... Good product. Good luck!”
“Easy install. It has stopped the gurgling sound in the sink and tub when the toilet is flushed...”
“Work well on my drainage. I should order the 1.5" size so I don't have to buy the converter.”
“I was so happy to get this and install it easily. If anyone had an issue with sizes, did you take it apart first? It was an easy and tight fit.”
“This thing works fine, but only when there is enough pressure to open the valve.”
“Lo recibí tal y como lo ordené, todavía no lo instalo.”
