This is an addendum to my earlier "earthquake resistant pitless connection" thread.
I now have a brass hose barb with 1" poly for the pitless connection. This line tees at the tank house with one side going to the house , and the other in galvanized steel, to the pressure tank switch etc.
This is an undergound tee, galvanized steel, with a brass hose barb, a galvanized nipple, and a brass gate valve, and a galvanized line into the tank house. The well guy said to use a 6" piece of PVC to make a access to the valve which is 24" below grade.
My question is this- is this a corrosion nightmare waiting to happen? All this will be in contact with the dirt, except for the valve which will have the PVC pipe around it. It will not be soaking wet , as there is a small roof overhang above it.
I am halfway thinking of changing the tee and nipple to brass, adding one more brass hose barb, and continuing the 1" poly up above the dirt, inside the tank house. So anything in dirt contact will be brass, poly, with stainless steel clamps.
My previous system had no galvanized below grade-it was all PVC. It lasted thirty one years and still no problem- the only piping problem was the galvanized steel in the tank house, it was internally corroded so bad it was nearly plugged.
This is the time to change it if i am gonna redo the well guys work, as the ditch is open and it is not an easy dig- (wires, etc).
Thanks for your comments!
