Where did the pipe coming out the top go? I don't know yet... |

Yeah, and I can't afford a learning curve.. You can do some rough calculations based on the cu/ft per min of the compressor at 100 PSI (roughly 200' head) and convert that to gpm of the water at 8 times that but I doubt it actually works that efficiently. This would be the max possible. I doubt it is more efficient than a submersible. Heat loss in compressing air, the loss in pumping, etc. a 3/4 horse pump these days is fairly efficient. I run a 1.5 and a 1 horse pump on my pool. 4 hours on the big pump and 2 hours on the smaller booster for the pool sweep and my electric bill is only about $50 more than not running the pumps. And the gold dredgers use these, but the head is only a few feet, not a 100+ For their air pumps. Yeah, I am just looking for the cheapest installation, easiest to replace. This system has no wiring or motors underground. I would have to put a storage tank in the basement but 100 gallons would be plenty. |

Where did the pipe coming out the top go? I don't know yet... There is a chance that was the output. You could try dropping a line down it and see if it goes to the pump. I am reasonably sure it's attached to the main line but it must be closed off at the tee. Being in CT the one thing I do know is I am going to find a pipe at least 4 feet down going the 35 foot run to the basement where it comes through the foundation. If it were open, the pressure from the pump would shoot the water out of the ground there instead of pumping up the pressure tank. But again, I don't doubt it's connected. |

Not sure really what I am gonna' do... Still rebuilding down the shoreline, short on cash until we get that place rented out. |
