I had a pair of beer engines for my birthday. I have given them a good clean out as they seemed like they not used for a very long time. They look rather old and are a Homark. I've so far only had them dispensing water, but will shortly set them up to my corines
One of them is working fine and no signs of any leaks. The other one however doesn't pull anything. When you pull on it the piston seems to travel much looser than the other one, so I am guessing that the black piston diaphragm has gone? Is that possable? or have I missed something else?
I have found that Colin Farrar has a spares kit for the Homark engine LINK
Some photos if that helps
Thanks!
