I have been very satisfied with my Stenner pump. Steve helped me tremendously when I put in the pool, and told me what to get a year or so ago, and it has worked very well. My only complaint is hauling all that bleach up to my ranch every 2 weeks. And of course, all those gallon empties... disposing of them. Feeling a bit badly about all those plastic jugs, I'm going to change. So I'm going to install an SWG this next spring. Since I'm off the grid, I wish they made a DC direct SWG. I understand that they are DC, but they all are AC in, then using an inverter to make the DC. With Solar panels so cheap now, I'd prefer just to put a dedicated solar panel to supply the power for the SWG. If the sun is not out, then no SWG, but so what? Oh well. I'll go from my inverters to supply the AC.
