I have another recommendation - Make sure to include a return flow=20
'shock absorber' of some sort.
I think Batson's guide describes a "hammer trap" in the return line.=20
Basically it is a vertical length of pipe coming off a tee in the=20
return. My think it's purpose is to keep a bubble of air trapped such=20
that it can compress when there is a pressure shock from releasing a=20
squeeze. I didn't scale this up quite enough (18" of 3/4" pipe). After=20=

about a year my press blew the filter cartridge off, and made quite a=20
mess. (Buy a couple bags of oil absorbent diatomaceous earth at the=20
auto parts store before you start playing with the oil.)
