I really need to find some time to update posts properly. 36 hours until all visitors leave, then I'll have plenty of time.
Update: I really can't take credit for this one. My darling sister visited for the weekend, and as we live close to a B&Q, she disappeared one morning to buy a toilet seat. I asked her to get me a radiator bleed key, as I'd found them on various plumbing websites for the princely sum of around 40p, but with a whopping £2.99 postage. She came back with one which cost a pound, and 'just to check it worked', proceeded to bleed all the radiators. Bless her. I can't even take credit for knowing how to do it; just for having the right book, which I highly recommend every house to have a copy of as it's a) funny and b) very useful.
Day 20: Mission complete.
