Monitoring your WaterMonster tank levels just got easier! Our new WaterGauge Kit allows you to clearly see the remaining gallons of water in your WaterMonster tank. This awareness helps plan for refills so your water station doesn't unexpectedly run out of water in a crucial moment. The hose splitter valve allows you to refill without having to disassemble the WaterGauge. Kit comes complete with water gauge sticker, fill level tube and a hose splitter.
