Struggling with frequent waste pump failures in your 3750 series van? If you’re constantly battling malfunctioning waste pumps and spending valuable time and money on replacements, you’re not alone. Your hydro bath’s twist-and-clean setup may be causing excessive back pressure—leading to premature wear and tear on your waste pump system.
Introducing the ultimate solution: This comprehensive, all-in-one retrofit kit is designed to optimize your van’s plumbing configuration and significantly extend the lifespan of your pumps. Here’s how:
Bypassing the twist-and-clean function reduces unnecessary back pressure, helping your pump operate more smoothly and reliably
Strategically lowers the pump position below the waterline, allowing natural gravity to assist flow—reducing strain on the pump motor and enhancing performance
Includes all essential hardware and reinforced hose lines for a seamless installation
Features a predrilled and clearly labeled mounting plate, making reinstallation intuitive and quick—even for weekend DIYers
This kit turns a frustrating chore into a straightforward, one-afternoon upgrade. Improve efficiency, cut down on replacements, and give your pump the support it needs to thrive.
