Fitted a new, quiet, non-crud encrusted filling wotsit for the kharzi in the new flat.
Loosened off, or so I thought, the gate valve in the hot water supply with a tool that it looks like my Dad made some eons ago for such a purpose. The wheel on the valve now goes, in the manner of those on the bus, round and round. Disfortunately it makes cock all difference to the rate of water flow. I think I borked something in the valve. New one purchased but getting it in will be a pain, as bother bits of pipe are fixed, one being the outlet from the cold tank the other plastered solid into its hole in the wall. I see hammering, swearing and light demolition in my future.
