Starting it is harder than I first thought. When I had posted last I had just done a quick tryout in the laundry tub. I was working but not 100%. I hadn't gotten all the air out of the siphon tubes. I had to twist it around in the tub to get the air our so it would work properly. So my solution is that I'm going to put a small drain cock at the top of the crossover in the siphon tubes so I can suck out the air. Hopefully this works.
I don't have a clue how I would figure out the max GPH
. it kept up with the tap in the laundry tub but that is only 60 gph
I believe. It is very large. I used 1" PVC
. I guess as long as it keeps up with the pump I add to it iamb ok. I was thinking the little giant 4mdqx-SC it claims 1350 gph
at 0 head and 900 gph
at 5 ft head. I have about 3.5ft head so iamb guessing about 1100 gph
on a 90gal tank would suffice. Also gonna add a scwd.
