Pressure test of water service procedure

This procedure outlines the requirements for pressure testing of water service.

Test the water service

To test the water service you will need to;

• Cap off all ends of the pipework, leaving one W45 open to connect the test bucket.
• Ensure there is an interconnection between the hot and cold by either removing the washers from a breaching piece or fabricating and installing a ½” copper connector between the hot and cold W45.
• Connect the bucket to the open W45 and ensure it is watertight.
• Fill the reservoir with water.
• Close valve B, leaving valve A open.
• Pump the handle until the pipework is pressurised and the gauge reads 1500 Kpa.
• Once the pipework is fully pressurised close valve A, this will hold the pressure in the pipe.
• Monitor the gauge to ensure the pipework holds pressure. The pipework is deemed watertight if it holds 1500 Kpa for 30 minutes.
• After 30 minutes release valve B and the water from the pipework will flow back into the reservoir.
• Disconnect the bucket from the W45.
• Remove the connector and / or replace the washers in the breaching piece.
• Cap the water service.
