Ram Pump for Cabin
Here's a ram pump I built for Chris and Nichole's cabin. Needs a length of 3" PVC for the air pressure chamber, some 1" poly input line, some 1/2" poly output line, a shut off valve at the end of the input line, some PVC/ABS combo cement, teflon tape, wire mesh filter on the end of the line at the spring, a little mesh hood for the relief check valve (keep the sticks out), and a storage tank at the cabin.

I'll send you this one. The larger one is too bulky to ship and probably more than you need. All connections on the smaller one shown above are 1/2". It needs teflon tape, PVC cement, a short length of 2" PVC pipe, 1/2" poly drive and supply lines w/ connectors (hose clamps or steel push fittings), a 1/2" union w/ connector (right side), wire mesh filter at the spring, a mesh hood for the relief check valve (keep the sticks out), and a storage tank at cabin. Flow is left to right.
