B&B RV Water Diverter Valves: 94227–94230 & Replacement Handles

A blue, red, black or white handle on a B&B Molders RV water valve indicates a different job. These are not four colours of the same universal valve: one fills the fresh-water tank, one bypasses the water heater, one routes a tank-flushing circuit, and one switches the water source for winterizing. Use the original valve number and its plumbing arrangement when choosing a replacement.

Match the valve to its function

Which part needs replacing?

Fresh-water tank filling — 94227

The blue-handled diverter changes the path of water from a suitable external supply to the RV's fresh-water holding tank. This valve is designed for the specified fill plumbing configuration; it is not a replacement for a pressurized city-water inlet or for the tank itself.

Water-heater bypass — 94228

The red-handled diverter is part of a water-heater bypass arrangement that prevents fresh water or winterizing fluid from entering the heater tank when the system is placed in its bypass position. Match the existing valve connections, orientation and routing before installation.

Holding-tank flush — 94229

The black-handled valve serves the tank-flushing water circuit. Flushing wastewater equipment is a separate job from supplying drinking water; maintain the manufacturer's required backflow protection and dedicated hose arrangement.

Winterizing source selection — 94230

The white-handled diverter changes a matching RV plumbing system between normal water supply and a winterizing antifreeze feed. The original installation determines how it connects to the pump and supply lines.

Before choosing a valve or handle

1. Read the existing valve or assembly number and identify the system it controls.
2. Check the number and type of plumbing ports and the orientation of the old connections.
3. If only the handle is damaged, match its exact replacement number; handle-only parts do not include the valve body.
4. After any plumbing service, verify operation and inspect for leaks according to the RV manufacturer’s procedure.
