The gang of three did shake out one small fault:- an air leak arround the steam chest, Johns leak detector (cigaret) traced a number of leak that we fixed by shortening screws that were bottoming out, a bit of Hylomar fixed others but one persisted, that was eventually traced to the little o ring arround the valve rod, the pocket cut into the steam chest for it, was way too small for the ring which was holding off the bottom cover, so this morning I cut the pocket bigger, and made some PTfE gaskets from material that John gave me, this seems to have solved the problem, its now running even better and the pump also seems to be bedding in nicely.

I tried elevating the out pipe this morning to give it a head to work against it managed a 10" head no problem, that was the length of the pipe, putting my finger over the pipe, stopped the flow but there was a considerable pressure their, the pump kept on working, and the coupling joints started to leak.
Hope this helps
