Application
WaterSwitch is designed to select between stored rainwater (when available) and
4
mains supply water, and send this water to your toilet cistern, washing machine,
garden and other non-potable household applications. It features automatic pump
control to minimise the use of electricity while saving water.
Rain water is used in preference so that:
- your water rates are minimised
- you conserve mains water and reduce usage of the city catchments water supply
- Harvest rainwater to its full potential so there is more space available in your
rainwater tank prior to the next rain shower
When your tank is empty, WaterSwitch seamlessly switches to mains supply so that
there is no interruption of water to your toilet cistern or washing machine. WaterSwitch
provides uninterupted supply to ensure you can flush your toilet - there will be no
unsanitary situations.
Do not use WaterSwitch for liquids other than clean water. Using corrosive, abrasive
or explosive fluids will damage the unit, and may cause personal injury or death.
Only Onga gives you an extended range of pumps to couple with WaterSwitch to suit
both inground or above ground water tanks. Featuring energy efficiency, low noise
levels, high flow and pressure, with a range of accessories there is a pump to suit
your needs.

Freezing conditions will damage the unit, as water expands as it
freezes. Ensure that the WaterSwitch is located so that it is not
prone to freezing, or ensure that the product is disconnected and
dried of water during cold conditions.
WaterSwitch is electrically connected. Ensure that it is isolated
from electrical supply during installation and any subsequent
service work.
Do not install or operate WaterSwitch in an explosive
environment or near combustible matter.
Brace inlet and outlet connections while fitting WaterSwitch.
Any movement of connections may disturb internal seals and
cause leakage. rst. Inspect WaterSwitch for shipping damage.
Preparation for installation
Read these instructions first. Inspect WaterSwitch for shipping damage.
Report any damage to your Pentair Water dealer.
If the incoming mains pressure to your property is greater than the specifi ed
1000 kPa, please fit a pressure reduction valve of appropriate capacity
upstream of WaterSwitch. This pressure reduction valve must bring the
pressure to below the rated value 1000 kPa. A recommended pressure is
500-750kPa. Fitting this type of device to your entire household will extend
the life of other appliances such as washing machines, hot water service and
dishwashers.
Ensure installation is in accordance with AS/NZS 3500.1 - Plumbing and
Drainage - Water Services

(Where Supplied)
2. Connect one end of the nipple into the pump discharge, threading it until it is
watertight. (DO NOT OVERTIGHTEN)
3. Connect the 1” Female end of the complete barrel union onto the protruding end of
the 1” Nipple until it is watertight (DO NOT OVERTIGHTEN)
4. Wrap a reasonable amount of threadseal tape around the 1” end of the union
nipple. Thread it into the base of the WaterSwitch until watertight (DO NOT
