After any heavy rain we end up having to repair the line on the first dive after floods, the sumps are small so therefore have high flow in small passage. We normally get the poly-prop in 220M bundles at about £4.50p a go.
In one sump we dived to an underwater dig a large amount of twin copper insulated wire had been left from an attempt in the 1970,s to blast a way through a blockage (it was used to fire bang). We used to dive with wire cutters just in case.
Pubs are good meeting venue and the beers are on you next time you are over Forrest
This is the entrance to Porth-yr-Ogof Tradesman me around 1988.
Leaving a Hepste sump entrance passage.
