The Rain Harvesting 100mm plain flap valve fits the end of overflow pipes and charged lines so water can discharge freely while pests are kept out of your pipework. The flap opens as water flows and closes when flow stops, which is how a flap valve works to keep vermin and mosquitoes from travelling back up the line.

  • Size: 100mm
  • Material: UPVC
  • Colour: Grey
  • Type: Plain flap valve

Suited to rainwater and water management systems, it provides uninterrupted discharge even in heavy rain. Fit it to the outlet of a 100mm overflow or charged line where you need a one-way water exit.

Brilliant Aussie deal

Been buying Rain gear for years and this is one of their better ones. The Rain Harvesting quality is excellent — everything was included and setup took under 10 minutes. Had it at the door in Brisbane within 2 days. My son immediately claimed it for himself so I had to order another. 10 out of 10.
