I heard of this drain back tap?, what is it called? how would I install
it? Where can I buy one? I have asked my plumber, but he has never
heard of it. Has anyone see any info on the net ?
"Make sure that the waterlines coming into the barn won't freeze up.
Sometimes, all it takes is insulating the above-ground pipe leading to
the faucet or tap. If not, you might have to install a hydrant-type
system, which send the water back below the frost line when not in use.
