I'm thinking about a new sump for myself and one of my ideas may help you out ... if you have the space.
I want the ability to perform a WC of larger volume, and the only way I can see myself doing it is to 'T' the drain lines to the return section and sock/pre-skimmer section.
I see having a pair of valves on the drains. One valve shuts off the flow to the socks/whatever, and the other valve would then open the flow to the return pump section.
Now, whenever I want to perform a WC, I close off the flow to the socks/etc and open the flow to the return chamber. Now I can utilize all of the volume contained in the sock/skimmer chamber for a WC. And all without turning off the return pump
I'm still working on it for my new sump, but thought I may as well throw it out there for you Mindy, and everyone else
