Under-sink water filter installation cost in Sydney

We mount the filter unit and connect it to the cold-water supply, then flush, commission and leak test the system. The installation includes:

• Standard fittings, a tee piece, isolation valve and tubing.
• Fitting the dedicated drinking-water tap where supplied with your kit.
• The drain connection needed for a compatible reverse osmosis system.
• System flushing, commissioning and leak testing.
• Cleaning up and removing the installation rubbish and packaging.

The service includes drilling stainless steel and laminate for the supplied drinking-water tap. Send a photo of the proposed tap position so we can check your sink or benchtop before you book.

Cartridge housings and quick-change filters

We mount the filter housing securely inside the cabinet, keeping it accessible for later cartridge changes. Standard fitting includes a tee piece and isolation valve on the cold-water line, tubing and the drinking-water tap supplied with your kit.

Check that there is room for the unit and access to change its cartridges. Have the filter, supplied tap and other kit parts ready before installation.

Reverse osmosis systems

Reverse osmosis installation also includes the system’s drain connection. We mount the RO manifold, flush and commission the system and, where your kit includes a tank, charge and check the tank.

Check the cabinet space for both the system and any tank. If the tap position, benchtop or existing water and waste connections need checking, send us the model and photos before booking. Any extra work is explained, priced and agreed before it starts.
