DIY installation instructions for the whole house unit

If you are a confident DIY’er, follow these instructions to install your Halcyan Water Conditioner.

Installing a Halcyan Water Conditioners will take an experienced DIY enthusiast up to 1 hour to install, and only take up 250mm of pipe next to your mains water inlet. Here’s a brief list of what we suggest you have ready, or you can download the full installation instructions below.

  • 1 x Halcyan water conditioner
  • 1 x 22mm+ single check valve (non-return valve)
  • 2 x straight or reducing compression fittings
  • Pipe cutters
  • Adjustable spanners
  • PTFE tape and jointing compound
  • 1 x container to catch any run-off.
  • Make sure the water is turned off at the mains stop tap.
  • Locate the best position to install the Halcyan Water Conditioner.
  • Ideally, locate the unit as close to the stopcock as possible, and before any T-off points so that all of the water serving the property benefits from the Halcyan system. Even the garden, as the ‘re- engineered water’ makes it easier for plants to absorb via osmosis.
  • You’ll need to leave enough space for the unit – placing the 22mm+ single check (non-return valve) between the stopcock and the Halcyan unit – and the connectors.
  • Total length required is around 250mm.
  • Measure, mark and remove the section of the pipe.
  • Install the non-return valve (in the correct orientation of the water flow) between the stop tap and the Halcyan unit using PTFE tape and jointing compound as required.
  • Install the Halcyan unit using good quality, correctly-sized compression fittings for your particular pipe diameter using PTFE tape and jointing compound as required.
  • Tighten all the joints.
  • Turn the water back on and check for leaks.
  • Always use a 22mm or larger single non-return valve, as some 15mm valves can limit flow rate.
  • If a pump/water meter is installed, the Halcyan unit should be installed no less than two metres before or after the device.
  • If space is limited, a vertical U-bend can be created to increase the available pipe length.
