OK....Just to clarify...This is my set-up...
On the fireman's side of boiler
1. CW from tender to CW pump-steam provided to pump from turret
2. CW from pump to FWH (hidden in cladding)
3. HW from FWH to HW pump
4. HW to boiler via top mounted check valve
On Engineer's side...
1. Side mounted injector-steam provided from turret
2. Injector brings CW from tender
3. CW injected to boiler via side mounted check valve
It's this last check valve that is at issue here. As I understand Dr. Wayne's & Sumpter's explanations, the housing opposite the intake hose on the top mounted check valve contains the pressure regulating mechanism...So no water feed possible there. This would be the case as well for the side mounted CV. So aren't the two check valves the same..?? Which was my initial question....
