I need to move my shower drain over two feet how to i do it?
Question:i am just moving it over 2 feet. it is a concrete slab foundation. the vent is already there. i am wondering what code requires here in texas. when i move it over do i need to worry about it being away from the vent two more feet and do i need any special requirements for the trap assembly
Answers:
The vent can be up to 5 feet away so that shouldn't be a problem,but you should be very careful and find out if this house used a post stress system in the concrete.This would be a grid system of cables instead of solid re-bars.It is called a post stress system because after the concrete has dried tension is placed on the cables to keep the concrete from breaking apart under the weight of the house. these cables have as much as 7,500 psi on them so you do not want to hit one of these when breaking up the concrete.It has been many years since I lived in Texas and installed these systems but if I remember correctly the cables will be 16" to 24" apart and will be in both directions and also should be 2" to3" deep you might be able to see evidence of this around the house.After the cables where tightened down the cable would be cut off and the hole was filled in with cement.On two sides of the house you should be able to find these plugs on the other two sides the ends of the cable with a foot was poured right into the concrete and there will be no plugs.You may want to contact you local building inspector and ask if this house has this system in it.
ask a contractor to do it for you.
anything is possible but I never heard of post tensile cables used on houses and if this a slab on grade it doesnt matter anyway. It wont violate any codes that I know of. The exsisting p-trap should work and just extend a peice of pvc the 2 ft and elbow it up just make sure you have pitch so the water will flow down at least a 1/4" per foot.
Good luck

Don't pay attention to Olger whatever. The guy who said he has done plumbing in Texas, is correct. Your house may have post tention cables, hell then again maybe not. You may just have rebar through out your entire house. I would personally deal with the rebar over the cables, if you hit a piece of rebar, cut it out of your way but, with the cables it is trickier. Like the plumber said earlier, you can see where the cables are but, only before the house is under consruction because as the house nears its finish stage, it gets skirted with a 1/2 inch of masonary mix, therefore leaving no trace of the cables location if done correctly. Like the plumber said earlier, don't be further than 5 feet from your vent, otherwise you'll have to re-vent. What you're doing isn't all that difficult, it's just that you need to be careful with the jackhammer. For a shower, all your fittings will be 2 inch. You'll need one 2 inch coupling, one pee trap 90, one pee trap and primer and cement. This is if it is a straight shot over to the new location. I to am a plumber and I live near Austin.
