return line

[mjs97]

does return line from valve to tank have to be 3/4 or will 1/2 work. its a 16 gpm pump.

thanks,

[mjs97]

also is return line under much pressure?

thanks,

no...it's under very little pressure.

your port on your control valve should determine the size of your return line. most are 3/4".

you can always go to a bigger size, but never a smaller size.

and, if it matters, this is the only line where you would put a filter.

Amen to both of MGA's comments. You'll build up quite a bit of back pressure with 16 GPM in a 1/2" line. That translates into wasting power, and creating unnecessary heat. You don't want either one on a log splitter.
Theoretically, you can run any amount of flow through a small line, but it takes pressure to do it. The larger the line, the less back pressure. It takes power to create pressure.

Brute force!

1/2 inch lines and 16 GPM.

That explains why I ended up with a 15hp engine on a 16 GPM pump on my rig!

I will swap them to 3/4, eventually. Maybe while I am at it go to a 22 gpm pump
