This vacuum breaker is also designed with ease of installation in mind. It features a universal thread size, making it compatible with most standard water inlets found on RVs. Additionally, it comes with a flexible hose, allowing for greater flexibility in positioning the vacuum breaker relative to the water inlet.

Its housing is made of durable, corrosion-resistant ABS plastic, while the internal components are made of brass for superior strength and longevity.

In summary, the Thetford 03947C Marine RV Electra-Magic Refill Anti-Siphon Vacuum Breaker is an essential plumbing accessory for any RV or marine application.
