i have opend up my wall that i want a walk through path and have found two capped off water lines and a capped of drain line. these are in a cement slab. my question is may i break up the slab around it and cap them off below grade and cement over them? and if so are the any precausions i shoud take?

thanks

You can do exactly that. Only precaution is to make sure that the caps are a good tight fit. Those lines are likely there for a future possible sink or washing machine.

If the drain is PVC, then cut it low and install a PVC cap. Supply lines can be capped with GatorBite caps or sweated on copper caps (if they are copper). Know what type of cap you are going to use before you start chipping out concrete as that will dictate how much you need to remove.

Or they might be left over from a previous remodel job. I'd see if the water lines are active, and if so, then I'd rather not cap and bury in concrete. What I would do is look for the nearest water source that they might originate from and, if feasible, I'd cut into the wall and cut the pipes and cap them there, then do the drywall repair. And then you could bury the pipes with no worry about leaks.

And the pipes coming up through the concrete are most likely soft copper, which could be damaged upon concrete removel, which means removing more. And actually, if you cut and cap at the other end, then you might not have to remove so much concrete. And if it is left over from a previous remodel, maybe someone already cut them at the other end.

Thanks guys they are from a previous remodel there was a wet bar there. i see the pipes are covered with a plastic wrap is that to prevent the concrete from damaging the copper?

Yes, assuming you're looking at a plastic other than sandwich wrap. Usually they use sleeves to slide over the pipe, and they're red for the hot line and blue for the cold line. But since you're working on someone elses remodel, I'm not sure what you're looking at.
