BACKFLOW ENCLOSURE

SIZE GUIDE

Start by choosing whether you need an enclosure for a reduced pressure zone backflow preventer or a double check. Then choose the pipe size you need.

The rest of the options can be left blank to see a variety of enclosures. However, you can choose different valve enclosure shut-offs such as NRS or OS&Y or specify the clearance based on your district's requirements.

First time buying an enclosure?

We'll make sure you remember the details.
