Walk into any irrigation supply house in the country and Watts backflow preventers are on the shelf, in the spec, or on the permit drawing. That makes Watts covers the first SKU most distributors ask about — and the first return if the fit is wrong.
Sub Zero Covers patterns every Watts SKU from factory dimensions and field verification. We are not rebagging someone else's universal size. We cut and sew in-house in the USA.
Top Watts models — and the covers that fit them
These three SKUs cover the majority of distributor volume:
- 007M1QT cover — the standard Watts RP size most yards reorder every season. If you only stock one Watts cover, start here.
- 009M2QT cover — larger RP profile for the 009 series and similar tall assemblies.
- 909 cover — legacy 909 and LF909 installs still show up on maintenance contracts. Having this pattern on the shelf saves a custom order.
Beyond those movers, we cover 957, 774, 800 series, and other Watts configurations listed in our distributor catalog. If the tag matches a Watts RP, DC, or PVB, check the model page or call with the full model string.
RP vs DC vs PVB within Watts
Watts makes more than RPs. Irrigation accounts may need PVB covers for 800 series vacuum breakers. Commercial jobs may run double-check DCV covers. The Watts brand page is your front door; assembly type pages sort the shape.
For RP-heavy accounts — irrigation, domestic commercial, multi-family — pair this page with our RP assembly guide.
Why distributors stock Sub Zero Watts covers
Exact fit means fewer returns after the first freeze. Manufacturer-direct means you are not competing with the brand's retail channel or a drop-shipper undercutting your counter. 3–5 day custom fabrication catches the oddball retrofit that universal covers miss.
Backflow testers and irrigation supply houses both reorder Watts SKUs because the model numbers are printed right on the tag — easy counter conversation, easy pick ticket.

Counter script that works
Train phone reps to ask three questions: make, model, orientation. That sequence routes 90% of Watts calls to a catalog SKU without measurement. When the customer says "big Watts RP," follow up with 007 or 009 — never hand them a universal large bag and hope. Your backflow tester accounts will notice the difference immediately.
Beyond the 007 and 009
The 957 stainless RP, the 774 double check and its DCDA version, and the 800M4 vacuum breaker each have their own fitment page with the spec-sheet envelope by size. Between them and the three small-RP pages above, the Watts line is covered from ¾" irrigation to 10" fire service.
