Rain Harvesting Mozzie Stoppa


Insect proof screens for pipes and tank outlets
Insect proof screens improve water quality by keeping pests out of the tank and allowing the tank water to breathe. Screens or Flap Valves must be fitted at all openings to and from the tank. These screens must have a maximum of 1mm aperture non-corrosive screening to keep mosquitoes, insects and vermin out of the tank.

They can be fitted to the end of all pipes that lead to the tank and all tank overflow outlets and keep pests out of the tank whilst allowing the tank water to breathe.

Mozzie Stoppa™ Screens incorporate a 0.955mm stainless steel screen moulded into a 90mm Male & Female PVC fitting. They are a versatile solution to insect proof the tank because they can adapt to fit to PVC pipes and adaptors leading to the tank and to all tank overflow outlets.

Mozzie Stoppa™ Screens are versatile and fit PVC pipes, adaptors and tank overflow outlets

Insect proof flap valves for pipes and tank outlets

They fit directly to pipes leading to the tank and to tank overflow outlets.

100mm Vented Flap Valve


The best kind of Flap Valves have a double seal, are self cleaning, and have flaps that cannot be over-rotated and left open. Vented Flap Valves allow a flow of air over the surface of the water which improves water quality and prevents a vacuum forming when large quantities of water are quickly drawn from the tank.

It is recommended that they be fitted with silicone and not glued. Rain Harvesting has a range of flap valves to suit 50mm, 90mm and 100mm pipe and/or tank overflow outlets.
