Backflow Enclosures in Pittsboro, NC

Pittsboro is a town of two housing worlds, and both have a backflow problem when winter shows up. Out by Fearrington Village and the older homes near the courthouse, you find irrigation backflow assemblies and RPZ devices that were installed above ground years ago with little more than a foam cover for the cold. Across town in Chatham Park and The Vineyards, the new high-efficiency homes arrive with modern assemblies — but many still sit exposed on an exterior wall or in a yard, fully at the mercy of the next hard freeze.

What an ASSE 1060 enclosure actually does

A backflow enclosure rated to ASSE 1060 is built for exactly this. It is an insulated, freeze-protected housing — often called a hot box — that wraps an above-ground reduced-pressure zone (RPZ) or irrigation assembly and holds the temperature inside above freezing. That matters because an RPZ relief valve is designed to dump water when pressure changes, so it cannot simply be buried or bagged. When the brass body or the relief port freezes, you get a split casting, a flooded valve, and an assembly that fails its next test. The enclosure prevents the freeze in the first place while still leaving the test cocks reachable.

We handle the whole thing: sizing the enclosure to your assembly, mounting it on a proper pad or wall, sealing it against weather, and verifying the assembly tests clean once it is buttoned up. If your existing RPZ was already damaged by a prior freeze, we can repair or replace it at the same visit so you are not paying for two trips.

Pittsboro joined the regional TriRiver Water authority in 2024, and TriRiver runs the local cross-connection program. That matters for enclosures, because a protected assembly still has to stay accessible for its regular certified test.

Under the North Carolina rules TriRiver enforces, assemblies are tested at least annually — residential irrigation with no chemical feed may qualify for every three years under Senate Bill 166 — always by a TriRiver-approved certified tester. We install enclosures that keep the test cocks reachable, so freeze protection never blocks your certification.

And because TriRiver recently changed its report process, we confirm the current requirements and file your test report for you when the assembly is due.
