Water pipe
The water pipe serving Ron and Barbara's house ran under our kitchen before entering theirs. Whilst he was installing their sewage unit, Geoff has diverted the water pipe so that it will not hold up our extension, and in the process has run a water pipe down to our allotment - there is no excuse next year for having small carrots!
I think it's about time we had another bonfire. And maybe time to order another skip...
