We then thoroughly brushed and cleaned down the surface with spirit to make sure it was free from grease. Once that had dried we gave the floor a coat of red oxide paint.
There was also lots of activity going on in the shed and one of the jobs I had a quick look at was the re-building of Dinmore Manor's valves.
Once Angela, pictured above, had these built back up, I was asked to remove Dinmore Manor's safety valve bonnet so that one of the top feeds could be inspected, as it was reported to be slightly passing. There are six brass screws which hold the bonnet in place which are screwed into the cladding. Five were easily removed but one had stiffened up due to the cladding moving through the expansion and contraction from when in steam and not.
After some patience and perseverance I managed to slowly remove the brass screw without damaging the head and lifted the bonnet clear to leave the top feeds exposed.
The next job was to slacken off the top nut (green), undo the stud (pink) which holds the surround for the valve down and then undo and remove the cap (yellow) completely giving access to the valve (red) inside.
The part being replaced is marked in red above which simply lifts out. There was a spare already prepared so it was simply a case of lifting the old one out, giving the inside a quick clean and putting in a new copper washer to improve the seal. I then replaced the valve (red) and tightened it all back down starting with the cap, then the stud and finished by tightening the top nut.
The last job was to put the bonnet back into position and screw it back down with the brass screws. Fingers crossed it will stay trouble free.
