Yes I have had my eye on it - I got quite excited when I realised I had a boiler for it, until I filled it with water. Leaks from everywhere! Scrap copper I guess.

Hi George. I have a plan for the boiler which clearly shows a 1/2" water gap at the backhead. I also have a part built boiler for Centenery which has a water gap, but closer to 1/16 inch I reckon. Perhaps there is something odd with the other measurements. I will be happy to send you a scan of my drawing - model engineer 5 June 1998 if you want it
Regards
John

Juliet 2. I found your picture extremely helpful and I think solves my query. If I had made it I would be pleased with it - we are not all seasoned engineers after all. I appreciate your help. Regards
John

Thanks for your replies It is a Bantam Cock loco. I can see the logic in plumbing the injector both ways suggested. I would rather work with an injector than the axle pump, which is hard to get just right. Julian, What is your view on Elder Statesman's suggestion of plumbing both injector and hand pump together? Can anyone recommend a good supplier for an injector?

Thanks all. Shawki - a very neat solution. I think the route via the axle pump will be easier for me though - I will have a go at that.
Thanks for your quick responses - a great forum.

Hello. I have a 3.1/2" gauge loco. It has 2 check valves (we used to call them clack valves I think?), one for the hand pump and one for the axle pump. I would like to add an injector - waiting in the station can need a water feed to the boiler. I don't feel up to adding another check valve to the boiler, and wondered if the feeds can be successfully combined into one check valve. I guess I will need more one way valves to protect each combined feed from the other so to speak! If so, which two feeds would be best to combine. Any advice greatly appreciated thanks John
