Setup went smoothly and very pleased with the products . I Finally have water on my off grid property, Couldn’t be happier .
We’re pumping into a big tank that runs into a little tank. In the summer we pump out of the big tank up to a tank in another pasture about 100 yards away. In the winter, we’ll move the float to the small tank. He rigged a pipe on the side of the tank to protect the float inside.
I’m so grateful that my husband will never have to climb that tower again.
