Good Afternoon from Brooklyn...

  I've been pondering on how to make a check valve
for my engine-run boiler water pump.  I looked at your
photo and thought, gosh, it would be great to have a
diagram showing the construction.  Any chance you
could do a rough sketch?  Maybe your angle on this
is better than what I've had in mind.  I added a photo
of the parts of my ram - I do not understand how it
could work w/o a check valve.  It's from 1926 - nobody
is left alive who saw it run and it was partly disassembled
when I purchased it.

Thanks,
Wayne
