Well, I damned up the spring and hooked up 2" pipe from the pond to the spring. I hooked up a generator to a 8000 gph pump and started pumping. The pump is overkill and pumps the spring pond dry in about 30 minutes. Can I run the 8000 gph mag pump for hours at a time if it is only getting limited water supply? I didnt know if a mag pump would be OK or not.
