I am trying to connect up the soil pipe on a new WC. I have ground off the collar of the 4" clay soil pipe level with the wooden floor, but however hard I twist or push, I can't get the finned end of the flexible connector (from B&Q) into the clay pipe (almost but not quite). Before realising I had an 'offset' problem, I had tried pushing in a screwfix standard rt angle connector with the black fins, and couldn't get that past the first fin either! Any suggestions, please, would be very welcome.
Thanks Steve & Mark - I have since ground all the barnicles off the bore of the clay pipe near the end & that improved matters. Grease did help, but the stupid flexible connector kept popping out the the clay pipe when I tried to attach the other end! I think the spigot end with the fins on was too short & didn't go far enough into the pipe to get a grip.
Anyway, I ditched the flexible job, & went & got another rt angle connector with a longer leg on it + a short offset connector & it seems to have gone together ok. A much more rigid job.
