Unloader question

[rj242 16]

I would like to purchase a flow activated unloader for my washer. The washer has a general pump and is 3500psi/5.6gpm. I have been looking at maybe a K-5, K-7 or ZK-1, but can't decide which one. Any help would be greatly appreciated, and also any recomendation on the best place to purchase one.

Thanks in Advance!

I have been doing more research on the ZK1 (K10), and have a question. Does this unloader come in different sizes or does one size fit all washer with different gpms?
