Stop wrestling with a sluggish or leaking flush. The Lippert 2022121976 is the genuine OEM replacement valve kit for Flow Max RV toilets, restoring proper flush pressure and seal integrity without replacing the entire toilet. It fits any RV toilet using a 1/2" NPT water inlet and a 1/2" outlet hose or grommet connection -- making it one of the most widely compatible valve repair kits in the Flow Max lineup.
The flush valve is one of the highest-wear components on any RV toilet. Over time, the internal seal degrades from mineral deposits, prolonged dry storage, or normal cycling -- leading to weak flushes, phantom running, or slow drips into the bowl. Swapping the valve kit is a straightforward DIY repair that restores like-new performance without the cost or hassle of a full toilet replacement.
Lippert part number 2022121976 is the correct service part for Flow Max toilets with the standard 1/2" NPT water supply connection. At only 0.05 lbs., the kit is compact and easy to handle in the tight confines of an RV bathroom.
Designed and sourced by Lippert specifically for Flow Max RV toilets. No trimming, adapting, or improvising required.
1/2" NPT water inlet and 1/2" outlet hose or grommet -- the most common configuration in Flow Max installations.
Weighs just 0.05 lbs. Easy to stock as a spare part for extended trips or full-time RV living.
Backed by Lippert's limited 1-year manufacturer warranty for defects in materials and workmanship.
