I am installing a 2nd bathroom and I did the most of work myself. I already plumbed the water in for the toilet and the sink. My house is on a slab, so I had to break up the concrete and make a trench for the toilet connection. My trench is about 2 feet wide and about 10 feet long and it's about 12 inches deep. I can see the horizontal run of the main sewer line a few inches down but I felt that it would be best for a qualified plumber to cut into it with a "T" and run the 10 feet of PVC to the toilet, including the drain for the sink and the vent pipes for both. I would then fill in the trench myself and run the connected vent pipes out of the roof. I was just trying to get some idea of the cost - one plumber said roughly $1600 and another said about $1900. To any plumbers out there or anyone who has had this type of work done, does that price sound reasonable? Any help appreciated. Thanks.

XTC...

First of all you want to be sure that a WYE fitting is installed here, but I am sure the plumber would know that.

Second, what do you think about trying this yourself? You've done/will do most of the work to this point anyway. We have some pretty good pictures and can explain what you will need to do to fix this up pretty easy.

You will need a sawzall, some bimetal blades, some 4 band husky type clamps and about a 1/2 day. You will be cutting in a NO hub cast iron wye fitting (available only at a local plumbing supply company). We are glad to discuss in detail.

Check out the images below... start you thinking on installation involved. The top pic. Shows you how to "flip" the rubber sleeve on itself. The next picture shows how to measure your fitting (or fitting and pipe) and then add a 1/2" for the ribbed rubber sleeve(s) and unstraight cut(s). The bottom shows the 4 band husky clamp and another picture of flipping the sleeve back on itself. The SS 4 band clamp slides over the rubber and then gets tightened down... NOT SHOWN HERE.

This is a lengthy post, pass most of the info. To get to the stuff you need. The poster (mechanickid) couldn't find a cast iron NO HUB wye fitting... I am sure you can find one at your plumbing supply house.

Let us know if we can help. I'm only the cost of a virtual beer... :)
