Ok . It’s not a water tight seal ( lifted drain further down the line and there is a slight trickle ) .

It’s a ‘partial’ test . No indication of any leaks in underground bunker

Because I want a water tight seal and I love expanding foam ! ?

 

But you've now screwed the pipe up, you can't use foam eater to clean it as it will damage the pipe, and there is a very good chance the foam will leave a residue on the nice shiny pipe that will trap crud and other sliding items...

It is well worth buying a couple of drainage plugs for testing and isolating.

The expanding foam was a bit mental.

Yeh I've  got a few bungs 6" and 4" always like to test drainage to 1m. To be fair though I've never had a bad pvc underground joint. Sometimes I've had an air bubble/lock in a temporary fitting or something which can play tricks on you
