Him next door had his drains cleaned and as an aside suggested that my
waste
(kitchen sink) underground pipe has collapsed.
Rubble at the inlet in his manhole and a total lack of water when the sink
tap was left on convinces me he is correct.

Anyway, sods law might apply, in that the collapse may be under the
neighbours block paving rather than my side so finally my question is:-
Can I remove pipe up to the fence and remove the blockage neighbours side
(only a 2 foot run from the fence to his manhole) and run a smaller pipe
inside the current one. If so are there large to smaller connectors etc
made
for underground waste?

Many thanks

Peter



Replace the same type of pipe thats there if you start putting in smaller
diameter piping you'll end up with a bottle neck syndrome.
Also dont put a sleeve inside another pipe as the ridge of the sleeve will
be a barrier for collecting crap.
