Thread: Pump for a gravity fed spring

  1. #1

    Pump for a gravity fed spring

    I have a home in NC (elevation about 4000 feet) it has three springs at varing distances,(from 100 feet to 700 feet away) ABOVE GROUND plastic lines carry the water into a 300 gallon tank, and gravity gets water into the home. The shower pressure is bad, and obviously the lines freeze easily. In the winter, I use the center line (about 300 feet long) by wrapping the bottom half (about 150 feet) with heated freeze tape, and the water moves well into the tank, the tank needs a pump that can be frozen-proof...any ideas?

    I don't know of any pumps that are made of rubber. Just kidding!

    If you have a cistern large enough that would overflow, it probably wouldn't freeze. Then install a submersible pump in the cistern and insulate the pipes from the top of water on to the house.

    The tank is 300 gallons. I tried to put an outside pump between the tank and the dwelling...it froze....it was a pump that had a built in pressure switch and small holding tank, it cost $300.00 dollars and I think it's now worthless. How would a sub-pump work?. (can you tell I'm a complete idiot regards to this stuff, and this coming from a Florida boy who had artisian water and a pump most of my life....but we NEVER had freezes like we have in NC)....

    Easy, just put it in the tank, wire it and plumb it to the house where you will have a tank and pressure switch. I recommend putting a Cycle Stop Valve on the pump also.

    easy?!?...you free this weekend?...the pump goes into the tank, connects to the lines into the house, and a tank with pressure switch is then installed along the pipes in the home?...is that correct?....will the pump be ok if it sucks up some occasional silt?

    I might be able to recommend a guy that can help if your near Franklin.

    The submersible goes in the cistern, has to be wet all the time. You can use poly pipe to pipe it to the house. One inch should be fine. You will need submersible pump cable (I can provide this too) from the motor to the pressure switch which will be installed on the Tank Tee that goes on the tank. The CSV will thread into the pump in the Cistern. It's not that hard, really!
