SM-XL Vacuum Breaker Adapter  Converts an Arrowhead PK1390 Anti-Siphon Valve Into a Straight Through Connection

• SM-XL ~ MAINLY FOR CANADIAN SPIGOTS!!! Will NOT FIT MANY USA SPIGOTS! For NIBCO-VBS-12-ASSE Hose Bibs & Watts Spigots Widely Used in Canada Where the External Thread Diameter is 1.25" (1-1/4" Fine Thread)

We Fixes That Leaking Vacuum Breaker Once & for All!!

External vacuum breakers on outdoor spigots often fail prematurely & leak water excessively, especially when using an irrigation timer or have a need for an always-on water connection. Unfortunately, most spigots have special fine threads, so that once removed, no other device can be connected to it. Also, vacuum breakers often have a set screw that is either corroded or broken off, making it difficult to repair or replace. We has solved that problem!

The female end matches the fine thread pattern & the male end has regular garden hose threads allowing the average homeowner to have a direct connection to their water timer system without leaks. Problem solved!

~Make sure you remove your old vacuum breaker & measure the external thread diameter so that you can pick the correct one

We make 2 models that fit most spigots with external vacuum breakers:

· SM01 - Fits most Arrowhead spigots with dual stage vacuum breakers, as long as you can get the set screw out & remove the entire vacuum breaker. Threads are fine & measure 1" in diameter. Includes Vinyl Washer

· SM-XL - Fits Watts Spigots Common in Canada may fit NIBCO-VBS-12-ASSE Spigots also. Threads are fine & measure 1.25" (1-1/4") in diameter. Includes Rubber Washer

Note: Spigotmasters are designed for outdoor, non-potable water use only. You must install an anti-siphon device downstream of the Spigotmaster where required by building code.
