Sealant for PVC waste to cast iron soil pipe
I recently got a plumber to do some work on my cast iron soil pipe. He
used some kind of thick, black, soft, sticky tar to seal the connection between a 40mm waste pipe and the (slightly larger) boss pipe on the soil stack. Can anybody tell me exactly what this tar is, and where I can get some? It's definitely not Plumbers Mait! For unforeseen reasons I need to replace the waste pipe. I can pull it out of the tar easily enough, but I will need some more to reseal the gap around the new length of pipe. Vaci |

This was not a normal silicone type sealant, it was black and a bit more 'rubbery/tarry' maybe. Anyway it worked fine. not sure where it actually came from, but nowhere special, a local shed or BM I would guess. It wasn't this brand, but this sounds like it: http://www.toolstation.com/search.html?searchstr=11002 -- Chris French, Leeds |

Sadly I will not be back to Manchester for a week, and I cannot remember its name. However I would think most Plumber Merchants sell it, it comes in a roll of varying widths, the one I bought cost a little under £6, did the job perfectly, very yucky though. -- Please do not email me at All emails to that address are automatically deleted before opening. |

This was not a normal silicone type sealant, it was black and a bit more 'rubbery/tarry' maybe. Anyway it worked fine. That's the stuff. It was easy to find in the local hardware store. However, it appears to be made out of the same stuff as the bowels of hell itself - it smeared itself very effectively not just all over the waste pipe, but also on fingers, clothes, threads and washers of compression fittings, joints of solvent weld fittings, carpet, taps and the lid of the swarfega tub. After exorcising the gunk from everything, I gave up on it and instead made a thick bung from alternate layers of rubbaweld and plumber's hemp. This seems to have made a tight and firm fitting. I then packed in more hemp and finished off with a hearty topping of Plumbers Mait. Hopefully tomorrow, after the solvent welds have cured, it will stand up up to the bathful of water test... Vaci |
