This tap is located in the water supply for my sink and washing machine. It has two holes in it that almost contantly percolates. The bottom line goes into the floor slab. Can't understand it's purpose. Pressure release? Trap primer?

No, supply comes from the water utility. What puzzles me is why water is percolating in its opening. Is the water coming from the drain line? If so would it be hydrostatic Pressure? It hasn't rained in a while here and we aren't that close to the water table.I think Stigster is probably right. It's also possible that it's a pressure relief valve. Is the supply a private pump that might need such protection?
Perhaps the valve is leaking slightly and the thin pipe that is supposed to take any leakage (or perhaps spillage when it is tested?) down and out through the wall has become blocked somewhere.No, supply comes from the water utility.
