Installation Guide for Plumbers
Find a perfect spot
Locate the main valve
Locate the property’s existing shut-off valve on the main cold water supply pipe. Sonic should be installed downstream, as close as possible to the existing shut-off valve, before any branches or appliances (except fire-suppression sprinklers).
If the property is fitted with a fire-suppression sprinkler system, Sonic MUST BE INSTALLED DOWNSTREAM OF THE SYSTEM to ensure the sprinklers will operate normally in an emergency.
Sonic is only for use with cold water systems.
Check direction of flow
Before you begin the installation, double-check the direction of flow. The flow of water must match the arrow indicators on the Sonic unit itself.
Check the space
Make sure there’s enough space for Sonic’s lever arm to fully open and close. You’ll typically need a space at least 25cm wide, 12cm tall and 10cm deep. Remember to factor in space for adaptors if required.
Also check that you can access the battery compartment.
Using mains power
If you’d like to operate Sonic on mains power, check the distance to the nearest available power socket.
Close the main valve and drain the pipe system
Close the property’s existing shut-off valve and remove as much water from the system as possible. The shut-off valve may have its own drain valve, or you can run taps and flush toilets until the flow stops.
If water continues to flow indefinitely, the existing stop tap may not be capable of totally isolating the incoming supply. You may need to turn off the mains supply in the road outside (after checking that the property doesn’t share a main with its neighbours).
Check the pipe diameter
Double-check that the compression couplers will work with the property’s existing plumbing.
Cut the pipe
Carefully cut the pipe with your pipe cutter and remove a large enough section to accommodate the Sonic unit and compression couplers. You’ll typically need to remove at least 21cm of pipe. Clean and deburr the ends as normal, then terminate the appropriate compression couplers onto the pipe.
Install the Sonic unit
Position Sonic in the space you’ve created and tighten the nuts onto each end of the unit, taking care to avoid cross-threading.
Do not over-tighten.
Open the original shut-off valve and test for leaks
Open the property’s original shut-off valve and observe if there are any leaks.
Treat leaks as normal with an appropriate sealing compound or PTFE tape.
