OK! So what size? = Already have 1/4"=20 vent, 1/2" supply. Should the return be larger then supply, similar to = oil=20 return lines? Don't want to have to do it three times (like I usually=20 do)

Hi=20 Tom,

Yes, you need=20 to run return lines, unless you have some sort of header tank that can = be used=20 for the return. I believe we can probably all agree that it's best = to go=20 back to the tank though. If you use a system like Tracy has, where = you=20 feed from only one tank, then you can return to only that tank as = well. If=20 you think you might ever install a duplex valve to feed/return from both = tanks,=20 then you'd better install a return on both tanks now. (You're = welcome Rich=20 <g>).
