More about this item

Raritan 221300 Toilet Accessories

The Raritan 221300 is a replacement vacuum breaker assembly for compatible Raritan marine toilet systems. The vacuum breaker is a safety and anti-siphon device installed in the freshwater supply line between the vessel's water system and the toilet. Its job is to prevent contaminated water from being siphoned back into the freshwater supply in the event of a pressure drop or backflow condition. On a boat, that is not a theoretical concern, and the vacuum breaker is what stands between the toilet's flush water circuit and the rest of the vessel's freshwater system.

Vacuum breakers work by introducing a small air gap into the supply line when the water pressure drops below a threshold. This air gap physically breaks any siphon that could otherwise draw water backward through the supply line. Over time the internal diaphragm or seal in the vacuum breaker can harden, crack, or lose its ability to seat properly, which compromises the anti-siphon function. A failed vacuum breaker may also cause a continuous drip or trickle of water into the toilet bowl even when the flush cycle is not active.

Common signs that the vacuum breaker assembly needs replacement include water continuously running into the bowl between flush cycles, visible leaking from the vacuum breaker body, or a toilet that takes on water slowly and unpredictably. In some cases a failed vacuum breaker can also affect flush water pressure and flow into the bowl during the flush cycle itself.

The 221300 is a complete assembly, which simplifies replacement compared to sourcing individual internal components. It is a genuine Raritan service part designed for compatible Raritan toilet models. Confirm your toilet's model number against Raritan's parts documentation before ordering to verify this assembly fits your specific installation.

Replacement involves shutting off the freshwater supply to the toilet, removing the existing vacuum breaker from the supply line, and installing the new assembly in its place. The vacuum breaker is typically located in the water supply line close to the toilet body. Raritan's service documentation for your specific toilet model covers the exact location and installation procedure.
