FAQ (Frequently Asked Question)

Q1: Is this 4" adapter with backflow preventer available in 5" diameter, too?

A1: Yes, here is the 5" version of this appliance adapter with backflow preventer.

Here is a appliance adapter, backflow preventer, that also includes a condensate collector and drain if you need it for 3", 4", or 5" diameter pipe. If you do not need the drain hole, Z-Flex tech support instructs to simply plug it. And, you can also buy the Universal Appliance Adapter with no backflow preventor, and buy the backflow preventer alone here.
