Install Tap & Pressure Release Valve on Water Bore

We recently drilled a modern submersible water bore in the Perth suburb of Waikiki.

Subsequently Jack attended to connect the bore to the client’s exsisting reticulation system and disconnect from mains water. He then installed a tap and pressure release valve for our Waikiki client. A tap using bore water is useful and it is also usually high volume.

You can see the PRV in this picture on the vertical PVC piping of the tap. The PRV is a safeguard against ‘deadheading’ the bore pump.
