Fantastic solution to floor joist in way of planned drain path. Bore drain hole and just remove couple of inches of joist making a shallow notch on top of joist about 3-4” long and 2” deep, side vent PVC drain sits on top of notched out joist. WAY better than removing a joist section and doing lots of carpentry to open a drain path, not to mention the possible complexity of pipes and wires running thru the space between joists where your drain would go. My guess is they will sell these side outlet drains by the millions. Product could be improved by making chrome drain cover screen able to be screwed in versus snap in. Also instructions about installing, none were in my package. Specifically, order of washer placement, directions to remove pop off drain screen so as to find 2 notches to use in tightening down screw in drain flange, and what tool to use to accomplish the tightening of the flange. I bought a “spanner ‘H’ shaped wrench” to go into the hand tightened flange and engage the 2 notches inside the drain. Also, the 2” side opening was too tight to get a 2” PVC pipe inserted more than about 1/4” so I used a sharp wide wood chisel and shaved off a small amount of PVC material by scraping all around the end of the piece to be inserted into side drain opening, worked great. I’d definitely buy this side drain item again although I’d like to see the price come down from the $56 I paid, but saved a lot of work that would have been required had this solution not been available.
