Since we have a need to move water from one place to another – mainly pumping out the ‘scary hole’ that collects all that water under the shower – we have purchased a transfer pump.  2077 got it at our local Tractor Supply Company.  He tested it out with a bucket, hose and the end of the hose running down the hill.  All went well.  Next time we take one water, we should be able to move the water out of that hole faster, and not have to lug very full, very heavy shop vac out to dump the water.
