I've been down with the flu for about a week. In that time I got impatient and considered getting the bsp model that is now up for grabs on ussolarpumps.com. They have the npt model on back order from the factory, but no idea when they will ship. After talking it out with them they offered me a substantial discount so I could get the bsp model and spend the rest on adapter fittings if necessary. So what I found was that the threads are so close that a little extra Teflon and you would have not known that the threads were different if it hadn't already been discussed or listed as such. Success. I got it up and running in no time and posted some video on YouTube. The new pump runs 135 bucks. Only a few dollars less than a chugger. But they also offer free shipping. So it only cost 135. It's barely bigger than the 3gpm model they make. And for those that are hatin' on all stainless pumps, I can tell you there are many benefits but the only one that matters is that I can put this pump inline and not have to worry about snapping the pump off at the head if things get too heavy. I'm hoping to see if they will offer up a hbt limited discount code or something to make it easier for those of us that might still be skeptical. I personally like the 12v pumps because I don't need extra extension cords (my control panel has a 12v 10a power supply built in). And I don't have to worry about my pumps getting wet and killing me. Anyway here is the video.
