Hi,
I got a couple of questions that I hope the educated people of this board can help me with. Im installing a basement bathroom and need some DWV help. Ive attached som pics to help explain. I am wondering if it would be a problem having the inlet of my ptrap using a street sanitary elbow while the output of the trap is just using a regular sanitary elbow. This makes the output side sit up just a little bit higher than the inlet side. I need this extra inch to maintain my downward slope tying into the main drain under the slab. I tested it with some water and it seemed to work ok but just wanna make sure. Like I said, it's only about an inch difference. The first two pictures are of the trap configuration. (the 1 1/2 opening that is coming straight out of the drain on the bottom is gonna be for a lavatory drain tie in and venting for the tub.)
Also I have a problem with my 3" drain up above that is fed by the upstairs bathroom fixtures. The main drain that is running down thru the slab is not straight up and down but about an inch left of center, in other words its crooked. Because the bathroom partition is running right along side of it, this is causing a problem. The studs have clearance at the bottom of the drain but as the drain goes upwards it leans in towards the partition wall and will wind up impeding the sheet rock once it goes up at about 4 feet from the floor. So, I need to make it plumb by adding about an inch of horizontal run at the top where it elbows off. The problem is that the horizontal run at the top is only about 7 or 8 inches and that is not enough room for me to slip in two couplers with an extra inch of pipe. Is there anyway of doing this without cutting out that entire section of plumbing and redoing it? I measured how much I would gain by just slicing the horizontal run in half and putting in one coupler. I would only gain 3/8". Any suggestions. The last two pictures are of this problem.
Thanks for any help you can give as I could really use it.
Take care,
Todd
