Recycle rainwater straight from your downpipe. The only rainwater diverter and rainsaver that filters all rainwater before it enters the water butt, tank, drain or soakaway.

The diverter then automatically shuts off the flow to the water butt when full. Collecting rainwater with the Gutter Mate is both simple and efficient, whether you are saving rainwater to a water butt, tank or a full rainwater harvesting system.

Downpipe (Drainpipe) Sizes

The GutterMate is designed to accept 68mm, 76mm and 80mm diameter and 65mm and 75mm square downpipes, without any adaptors or reducers, other than the square to round adaptor supplied with the filter, if needed as per the instructions. This adaptor is used if your square downpipe is fitted using “close fitting mounting brackets” to your house.

What's in the Box?

Each box contains:

  • Gutter Mate Filter Square to round adaptor for Square Downpipes
  • Blanking Cap for Diverter outlet, if needed.
  • Hose Adaptor for Water Butt Screws and plugs for fitting Gutter mate to wall.
  • 500mm of hose to connect Gutter Mate to water butt or tank. Subject to distance between Gutter mate and water butt / tank a longer length of hose may be needed. Which is available their website.

The GutterMate rainwater diverter and filter is made from Polypropylene and comes in a black colour.

The product is supplied with the fixing screws and mounting bracket. There are 5 parts to the filter which are a slide fit into each other. The filter basket filters all the rainwater which falls down the downpipe.

The user has the choice of using the Diverter outlet ( the smaller of the 2) or the main outlet to divert the rain water into a rainwater tub or rain water harvesting tank.

If the degree of filtration is inadequate for the use you are putting the rain water too, we have a Fine Mesh Insert available which fits into the filter basket and provides a far higher degree of filtration (800 micron). This will allow you to use the rainwater in your pressure washer and for washing the car.

If your guttering is attached to a square downpipe, there is an adaptor in the box to allow the filter to be fitted to square drainpipes which are installed with close fitting brackets. If you have standard brackets you will not need the adaptor.

This rain water filter goes a long way to solving an age old problem associated with guttering and drainpipe systems on buildings. The biggest problem with guttering is it gets filled with leaves, stones, sand and moss. The result can be blockages or over flowing gutters.

This in turn can lead to damp penetrating the wall of your building or damp getting to the roof joists. Gutter blockage and overflow can lead to extremely expensive repairs to your property. The other problem associated with blocked guttering and drainpipes is the inherent danger of inspecting and cleaning them. Use of ladders should be avoided at all times if there is an alternative, namely the Gutter Mate Filter.
