changing existing CL??????

I only put ball valves before and after pumps to make removing them for cleaning easier.

I bought my 4-Way used locally.

you only need ball valves on the outputs if the 4way was under the tank, since your over the top, you don't unless you're want to limit the flow in one or more of the lines.

Ok thanks I figured that and I would only use ball valves if I skipped the 4 way and just piped it right from pump as obviously the closer outlets to pump would blast way harder than the farther outlets
