As we saw in the Bison Water Pump Review, this is a very well designed pump system – for use, installation, and servicing. It comes with a well-written installation manual with drawings and parts list. The Bison pump is made in America – specifically, it is made in Maine – and it shows. The workmanship is excellent and shows an attention to detail that is seldom seen in today’s “Made in China” world. The level of quality is top-notch all the way around. In a word, it is solid.
The objective was to have, in a single well:
- A conventional electric pump that was immune to the pitting and holes that result from having sulfur in the water. Last year, after only a few years in place, the bottom section of galvanized drop pipe had to be replaced due to at least 13 holes in the pipe.
- A hand pump to function as a backup in case electricity was not available. The hand pump needed to be very sturdy and able to function for many years without the need of servicing or parts replacement.
This project consisted of pulling the existing submersible electric pump and its galvanized drop pipe and replacing it with the following:
- At the bottom – the submersible electric pump.
- Just above the pump – a 5′ section of stainless steel pipe.
- Above the stainless steel pipe – the Bison in-line pump cylinder.
- Between the Bison pump and the surface – 1 1/4″ Schedule 120 drop pipe with 3/8″ stainless steel sucker rod.
- At ground level – the Bison pump head.
