Those have to be dry well FH! Wet wells are made of brass and will burst if temps too low CA has wet wells, how do I know I installed a ton. Upper elevation in CA and any area subject to low temps we install dry wells. ! Dry wells are made of cast iron and shut off below freeze zone. Not much value in cast iron! Maybe at most 10 cents a lb! All they accomplished was vandalism.
I didn’t know that. I just assumed the design was “standard,” more or less. These guys were working a cold climate.
There are also dry hydrants that are nothing but a connector for the pump truck with a pick up pipe in the river or creek near by. Not hooked to the municipal water supply.
