Thanks David,

I only have to pump uphill about 4 feet, but I think you're saying to look at the flow chart to make sure there's enough flow at THAT head height. Will do.

I really like the Badflash Intex and the fact it only uses 80 watts, but it's only 600 GPH. I could use 4 of them, but my guess is that they would use more wattage than a single bigger pump. I do want to keep the wattage as low as possible for future PV solar or hydro. Intex does have a 2500 GPH at $130. It uses a filter, which I don't want, but maybe it can be bypassed. I also like the idea of an external pump rather than submersible.

Thanks for the tips. Will check those Danner and Little Giants, along with flow charts and wattage. Whatever pump I get, I'll buy two so there's a backup.

Gary
