Silly time to be doing it, but just about finished re-ferkling the kitchen. New doors on the old but good home made base units and all new appliances. Last job was fitting the new built in oven. It's not as tall as the old one so built a new shelf for it to sit on. Get it in place with a bit of a struggle and push it home - looking forward to cleaning everything up and having a break. Although we're out for Xmas day.
So I push it home and it stops about 1" proud. It's only deeper than the old one and fouling on the pipes behind. This is the main run from the cellar to upstairs - hot and cold water, gas, and the heating flow and return. So I measure things, and it's only fouling on the heating pipes and cold water feed to the kitchen. Luckily, the heating pipes can be moved enough just by rebating the battens the clips are attached to - there's more than enough slack in the cellar. The mains cold water one will need surgery, though. But at least it's the easy one to turn off. So do that and cut into it. Disconnected the output from the stop c*ck in the cellar to drain down fully. And re-jig it all with solder fittings. But the horizontal run to the kitchen tap has still some water in it and doesn't want to solder. And too tight for a compression fitting - if I had one. Not easy to try and unclip the pipe to drain the water as it's all behind the fitted base units. ;-(
So I had a cup of tea after a good curse.;-) Then had a brain wave - push air through the pipe to dry it. I've got a HVLP spray set and the hose connection is the same as the washing machine. Coupled it up and left it running for about 15 minutes - the air from it is quite warm. After the first minute or so, no more water drips come out of the pipe, but I leave it on for a while. And sit down to listen to some of Nine Lessons and Carols from Kings.
Did the trick. I'd guess if you have a vacuum cleaner which can blow this would have worked as well - just gaffer tape the end on to a tap.
