We have been in a new (to us) house for 3 months or so. In this time there has always been a tiny damp patch in a first floor bathroom, on the ceiling next to a soil pipe boxing. I dismissed this as being a ‘cold spot’ in the roof, maybe a condensation issue. As I was in the loft today I thought I’d take a proper look only to find the following ‘bodge’.
The soil vent pipe is terminated to a pantile vent thus-
The corrugated vent tail pipe has joined to the elbow on the vent pipe using ‘Mk1 grey duck-tape’ in which a precisely positioned cut has been made to any ensure outfall from the vent drains into the kitchen measuring jug carefully positioned below. This had obviously reached its design performance limit as it was full to the brim! I would guess that the amount of moisture entering through the vent is quite small, probably an infrequent drip, otherwise the damp would have been much, much worse.
Opening this out to the world of knowledge on this forum:- is this a case of finding a suitable adaptor between the corrugated pipe (assume for 110mm dia UPVC) and the SVP (which looks to be 82mm(?- it is certainly smaller than standard SVP I’ve seen), i.e. outside the corrugation / inside the SVP, assuming such a thing exists. Can it be that simple a fix (if so it worries me why this was not done in the first place!).
