This flanged 4 inch Tank Overflow Kit is the Overflow Fitting installed on all Poly-Mart Rain Harvesting Tanks. There is a standard rule of thumb when plumbing your rain harvesting system. Rainwater has to be able to exit your tank (when it's at maximum capacity) just as fast as it can enter the tank. If you do not have an adequate sized overflow, your system could back-up and fail during a large rain storm.
All sales through distribution. Monday through Friday, 8am to 5pm (PST)

The 4" Tank Overflow Kit comes installed on our 1500, 2500, 3000, 5000 Short, 5000 Tall Rainwater Harvesting Tanks made out of Fairfield, TX. A Tank Overflow is one of the most important components that make a plastic tank suitable to collect Rainwater. A main rule in the proper collection of rainwater is to insure your tank can overflow water at the same rate it can enter your collection tanks. Equipped with a removeable screen, these overflow kits are designed to insects and critters and other pests out of your system while also giving you the ability to clean out debris. The High Flow Flap Valve is a lot of times sold with the 4" Tank Overflow Kit. The Tank Overflow Kit is also available in a 3" version!
Keep mosquitoes, birds, squirrels, frogs, and all pests out of your rainwater tank while allowing it to overflow.
