Capping off CI "Y branch"

[Alz0r]

Hi all,

Got called out to a leak on this cast iron branch today. (In a pub toilet - gents 1 1/2" waste going into one of the collars, the other one was "capped off" - cap was actually loose).

The 1 1/2" waste was being "held in" the cast iron with silicone, and had come loose.

As you can see, I denso'd it up for now and will be returning tomorrow AM for a more permanent fix.

Apart from ripping out the CI, all I could think of was 2 x flexiseals (3" down to 2" then have a 2"rodding eye in the redundant branch, and a reducer for the urinal run in the other).

Any thoughts?

Cheers

Well I managed to get a flexseal over the CI but theres a very slow drip coming from the CI end of the sleeve. The surface of the CI is uneven (from rust and paint) so I'm going to go back tomorrow AM and try and smooth it out.

I've tried a wire brush, with little effect, I'm going to try running my grinder over the biting point of the jubilee clip, that is unless of course someone can offer me a more effective alternative!!

Cheers

Try a few wraps of closure tap round the pipe then tighten down on that.

thanks, i'll give that a go, but wont the water just get under the tape and still escape ?

i did consider using denso but its too "squishy" and will just thin out under pressure from the jubilee...

Take the tape 1/2" over the edge of the pipe and bend it in.
