Downpipe mounted rainwater filter and rain diverter kit.  Highly efficient and quick and easy to install. The 3P Filter Collector fits all standard UK downpipe sizes 68mm to 100 mm without needing to be adapted.  Quality stainless steel filter mesh and durable plastic body.

Collects rainwater while filtering out leaves and larger particles. The particles then continue on down the downpipe, along with overflowing water when your water butt is full.  

Outlet fits 75mm (3"), 50mm (2") and 32mm (1 1/4") pipes or hose. THIS UNIT COMES WITHOUT HOSE AND IS DESIGNED FOR CONNECTION TO YOUR OWN HOSE ASSEMBLY, OR DIRECTLY TO TANK WHERE AND WHEN POSSIBLE. For fitting to all waterbutts and thin-walled tanks up to 30cm from the downpipe, please choose the 3P Filter Collector with 3P Universal Link Kit instead, or contact us for hose sizes and other connection kit lengths.

  • Filters and collects rainwater for the best possible water quality.
  • Fits all UK round downpipes from 68 to 110mm, square 65 to 75mm (not just 65 square and 68mm round).
  • Durable high quality plastic body, filter mesh made of stainless steel.
  • Once the tank is full, the filter acts as the tank overflow.
  • Can be turned to 'off' position to stop diverting water.

Included Components

None. The fitting/sealing kit to your water butt (including grommets, multi-holesaw sets etc) comes with the wall tank you purchase on this site.

Alternatively you can purchase a multi-holesaw set with rubber grommets separately.
