In my moomba there is a single Simer pump to fill the 2 rear bags. The bags have 4 fill/empty ports each. There is a one on each end of the bag towards the bottom and then one towards each end on the top of the bag. Originally I had the fill/empty line coming out of one of the ports in the top of the bag, but the other day I moved it to one of the ports at the end/bottom of the bag.
Is there any advantages or disadvantages to doing it either way?
Using gravity could only help. But your pumps are impeller style: they'll pump air, water, snot and anything in between. So, its not necessary on your system like it would be on an aerator system, could help. If that makes sense...}
Thanks for the help guys. I just grabbed some silicone to help seal the fill/empty fittings.
Last year when I had the lines going into the top of the bag it was really annoying when emptying because you really had to pay attention or the pump would burn up. I think I burned up 2 of them last year.
You guys have any idea on a front 1000# gravity game bag? It only has one fitting on each end on the top. I do have a one way valve on the overflow line. As long as a fill the bag all the way so there is no air in the bag will it be fine?
Also the fill empty fitting is a metal fitting that is screwed into the bag. It is kind of hard to explain but there is no collar to stop it. You can actually screw it in too far and the fitting would fall into the bag. Should I just use silicone to seal this or some kind of glue/adhesive to hold it and completely seal it off.
