PestFlap Products
PestFlap comes in two builds, PF3 and PF4, so whether you’re fitting a US toilet flange or a UK floor drain, there’s a version engineered for your exact connection. Pick the wrong size and you’ve fitted nothing at all, so this page exists to make sure that doesn’t happen.
Which PestFlap Fits Your Drain?

Still not sure?
Send us a photo and the measured internal diameter of your drain opening, and we’ll confirm the right fit before you order, not after.
Confirm Compatibility Before You Order
Every drain is slightly different. Pipe material, fitting type, available insertion depth and overall condition can all affect the fit. For anything outside a standard setup, check the technical drawings for your chosen model before ordering, or send us photos and measurements and we’ll confirm compatibility directly.
