Check valves
Where do i need check valves? I have 3 water supply means, and a check on the main line going into the boiler. Where else would i need them. I have a stack blower, whistle valve, blow down, main engine steam, and saftey line of course, and steam lie for injector.

Re: Check valves
Anywhere where water is going INTO the boiler, and also immediately after whatever pumping device you have (i.e. hand pump, engine feed pump, duplex, injector (not really a "pump" per say)).
If you have an economizer I would think it would be safe to say you need one before and after the economizer in case of a leak.
