Breeze blocks / concrete blocks
I have a drain of porous, ribbed, very old clay pipes, leading from my septic tank.
A short area (18") has collapsed. Rather than try and replace the pipes in any way I'm thinking of installing an inspection chamber at the site. Would this be the best approach? And what am I looking for? Drainage Sales have: 450MM INSPECTION CHAMBER COMPLETE SET WITH POLYPROP COVER - FOR 110MM DRAINAGE CODE: 450MH1 which looks as if it might do the trick. But I have absolutely no experience so any comments would be very welcome. Keith |

Keith It might be difficult to get a proper water seal between old pipes and the new chamber to the satisfaction of building control officer but I doubt that you will be showing it off ;-) Pragmatically, for a outflow pipe it should do fine IMHO |

Ah, here you go: https://www.toolstation.com/flexible...-to-pvc/p54240 I was going to suggest that! Maybe don't actually need the inspection chamber, just a length of plastic and two of those? How far is this from the nearest inspection point? ISTR I have seen cheap USB drain inspection cameras with a reasonable "reach". You might actually get away with a 300 mm chamber. I used one of these to replace a sort of gulley/standpipe made of clay in my foul drain outfall. The other thing which can be done for damaged clay drainage pipes is sleeving with either epoxy or polyester reinforced fibreglass. I had a four or five foot length done for less than £1k (including pre and post videos). They use an inflatable balloon to hold the sleeve in place while it cures. |
