  1. Simply Amazing

    Posted by JIM on 26th May 2015

    This is simply an amazing device. Cut existing PVC leaving room for AA-1. Throw in some primer. Throw in some rubber cement. Twist in place. Done. This is the epitome of KISS.

    The beauty of this device is I can now VISUALLY check at regular intervals buildup rather than guessing when was the last time I clean out the line and if I should clean it again.

    The device is solidly built. The gasket, hard to see in the picture, is well seated in the frame. The pullout flapper and included extended elbow adapter fits with precision into the device. There appears to be a good deal of time invested in creating a quality product.

  2. Excellent Product

    Very good product. Well worth the money.

  3. Cleared up my drain problem in minutes

    Posted by Unknown on 25th Sep 2014

    The plumber said the condensate drain was blocked and needed to be replaced at a cost of $331. I went to ask.com and there were several solutions. I chose this product, installed it in minutes, hooked up my Wet/Dry vac and the problem was solved. Now I can clean the drain anytime I want.
