Oh John, don't mention 'plumbing' to me! For several weeks I've had a 'haunted loo' - it kept flushing all by itself, even in the middle of the night, and there's only me in the house - scary!. As I'm on a water meter, this was costing me money. But my favourite plumbers (Dempsey) would need to be paid of course.
Then, a few days ago, the Haunted Loo flushed continually without stopping, late one evening! I tried and tried to turn off the stop-cock under the kitchen sink, but it was too stiff for me. So I ran next door to my kind neighbours, and the husband brought a spanner and got my water turned off. I rang Dempsey's emergency number and a lovely chap arrived immediately. He told me I'd have to wait until the morning as he didn't have the requisite part on his van. So I spent the night with all water turned off, unable to flush my loo at all. He came back early next day, fixed the loo and now I'm singing in my head that song 'The Honey Cart' by the Singing Postman ("Whenever he's bin, yew kin goo agin, as regular as can be!" hee hee!
