A leaking toilet base is one of the most frustrating -- and potentially damaging -- issues in an RV. Lippert's 2022121983 kit gives you the exact bottom gasket and mounting hardware needed to reseal your Flow Max toilet at the floor flange, stopping leaks and restoring a solid, odor-free mount. One kit, one fix.
Over time, the bottom gasket on an RV toilet compresses, cracks, or shifts -- especially in rigs that see regular road vibration. When the seal fails, sewer gas and moisture can escape around the base, leading to odor, floor damage, and unsanitary conditions. This Lippert replacement kit addresses the problem directly with a properly sized gasket and all the mounting hardware needed to reseat the toilet securely.
Because it is engineered specifically for the Flow Max toilet line, the gasket profile and hardware dimensions match the original installation tolerances. You are not improvising with a generic wax ring or hardware store bolts -- you are restoring the toilet to factory spec.
Designed to the same spec as the original Flow Max bottom seal. No trimming, stretching, or adaptation required.
Mounting hardware ships in the kit so you can complete the job without a separate trip to the hardware store.
Fits any RV toilet that uses a standard 3.78 in. ID floor-flange seal, not just Flow Max models.
At just 0.05 lbs., the kit stows easily and is a smart item to carry as a spare for extended trips.
While designed for the Lippert Flow Max toilet, this kit is compatible with any RV toilet that uses a 3.78 in. inner diameter bottom seal. If you are unsure whether your toilet qualifies, measure the ID of your existing floor-flange gasket before ordering.
