New plan. Since I already have some 150' of black garden hose on a spool, I'm going to replace to hose between the pump and pool with a new hose and will have a in-line manifold so I can simply hook up the garden hose and spread it out in the yard. I'll put a valve in the hose so I can control how much of the pump's flow is going throught the garden hose.
In my mind it works great, so we'll see when I get it put together.
