I have a spare well, not hooked up to the house (it is a relic from before the neighborhood got city water), and I have been using it for my pond water changes by having a sump pump hanging in it by a rope and plugged into a remote with a garden hose hooked up to the pond ... push a button - fill the pond up! The water is clean and has acceptable PH, KH and GH readings.
So I have been wondering how I might change to a trickle system, without getting an expensive well pump and pressure tank, that would cycle on and off all the time. One idea I have is to find a low wattage submersible pump like a Laguna, in a size that by the time it overcomes the head loss of being down the well, only a trickle is coming out (I'd run it 24/7). Most of the year the water is sitting 8-10ft. down in the well plus another 2 ft. to pond water level, so a head of 10 to 12 ft.
The negative would be experimenting (maybe with borrowed pumps) to find the right size, but I also wonder if running at the absolute max head would put a lot of excess wear and tear on a mag drive pump ... does the pump care?
Any opinions or better ideas?
