Don't waste your money on this product. I have used four plugs on four different pipes and NONE of them worked. When I came back a month later and removed the plugs, the sealant was completely dry and I had to cut off the ends near the hose to get at the remaining sealant. The problem is that it comes out in a 1/2 inch tube of sealant. Very frustrating. As an aside the contractor left me a partially used tube of caulk which he taped over and this tube has been in storage for over a year and the tube has not dried out.
