A few things;
Is this ok to do under the electrical wiring regulations?
As the cables will certainly not reach to the new socket outlet, would it be in order to join an additional length in the lower socket, sealing the joint with some kind of waterproof - er seal? If so what can do this job?
Also, is there (does such exist) some kind of kit for water-sealing the entire distribution board switchgear - ie Consumer unit, mcb units meteres etc? The work (and cost and finding a suitable high location) of moving it would be a last resort solution.
Who sells sandbags? The Env Agency tell us to get some - but never where?
Ditto for airbrick waterproof covers
Fianlly they advise fitting non-return valves in the watre supply. Reckon I can do that ok and B& Q probably have them. Where should they be fitted through. Hot and cold supply?
Thanks for any pointers on any of the above.
