: Hi!Im sorry that I dont have the answer you are looking for, but wondered if you would tell me where I could purchase a laundry tray.Thanks,Gary Jensen: : I am a do-it-yourselfer and am currently constructing : : a laundry room to be located inside a large closet : : inside a half-bath,which I am also constructing at : : the same time.: : My Question is: How do you plumb a 1 drain line into : : the 2 washing machine drain line?: : My township inspectors are requesting that I install : : a laundry tray where the washing machine will be : : located. This laundry room is over an 8 foot crawspace : : annexed to the basement and as such all of my plumbing : : is exposed under the floor joists.: : The laundry tray I purchased comes with a knockout : : in which a 1 drain is to be installed to drain water way : : should the machine ever leak or overflow.: : I had thought the 1 drain would have to be trapped : : but then realized any water in the trap would dry : : up since the tray drain will never really be used.. : : So I figured I would run the 1 drain into the 2 laundry : : drain before the p-trap.: : But there is another problem. The wall the standpipe : : is located in used to be an exterior wall (this laundry : : room is now an enclosed porch converted to living : : space and a half bath). As such, immediately below : : is the stone foundation.: : So, in order to run the 1 drain into the 2, I have : : to extend the standpipe down through the wall interior : : close to the foundation, install a 90 long turn ell and run : : horizontal for about 1 foot, then install another 90 ell to : : go vertical again, install a 2 wye, and THEN the P-trap : : for the laundry drain, come out of the p-trap into a sanitary : : tee. The bottom of the tee would complete the run to the : : house drain, while the top of the tee I would install a : : 90 degree ell, run horizontal back into the wall, install : : another 90 ell to go back up through the interior of the : : wall and connect to the existing vent pipe. In the 2 wye : : I would install a 1 bushing to accept the 1 drain.: : This route puts my p-trap for the washer standpipe about 4 to 5 : : feet away from the top of the standpipe, and remember there : : are two turns along the way. Is this acceptable? It seems : : there has to be a better way.: : thank you. : : Rich: Rich, : When draining the washer pan, do not connect to the waste and vent system except through a p-trap that will regularly get water for the trap seal. ( a trap primer would work)You may ask the inspector if the 1 drain for the pan has to connect to the waste and vent system. The T&Ps on water heaters dont.: Q.What is a vent, and what does it do for the plumbing system?: A. If you look on your roof, you will see pipes sticking out of the roof aprox 12 high. �For every pipe that goes down, one needs to go up. �The obvious reason we have vents is that sewer gases need to be vented outside of the dwelling. �Not so obvious is what happens if they are not included in the waste and vent design. �Imagine yourself at McDonalds drinking a soda from a straw. �If you put your thumb over the straw, you can pull liquid up from the cup. Remove the thumb and see it instantly drain out! �When liquid goes down a pipe, air needs to follow it. �Without the vent pipe, the draining liquid will try to suck air through the P-traps on the plumbing fixtures,(tub, sink, etc.) glurp, glurp! �If it manages to do so, you may know it from the smell coming from the now dry seal on the P-trap. Without vents, draining one fixture may cause another fixture in the house to back up, yuck! A waste and vent system should keep sewer gas out of the dwelling and drain every fixture well. � : Regards, : Terry Love
