I am replacing part of an existing drain built about 1970 in saltglaze pipe, this will run under a new extension.
With 1 metre head, the leakage from the old drain section was about 6 times allowed on Test. So I replaced another 3m of the saltglaze hoping to eliminate the worst joins...but the remaining section still leaks (at proportionately slower rate). Each joint seems to have some leakage with a 1m head. What I need is Radweld for drains! The pipe itself is fine, most of the joint is OK, but it well - leaks. Apart from getting it lined at £50/metre, is there a cheaper alternative; I can't replace too much more without vaste concrete breaking etc.

What diameter is the pipe that's leaking?
There is no 'Radweld' for pipes - you either line them, which is just not practical on the vast majority of small residential jobs, or you replace the lot.
In fact, it's often easier, quicker and cheaper to replace the lot rather than waste time, materials and effort trying to patch knackered gaskin joints.
