Winterizing an RV freshwater system is far easier with the right inline diverter valve. The Thetford 94230 lets you switch your water pump's inlet between your normal freshwater supply and a jug of RV antifreeze -- no need to disconnect hoses, no improvised fittings, no mess. One lever movement redirects flow so antifreeze is drawn through the pump and distributed throughout the plumbing lines, protecting every line, valve, and fixture from freeze damage.
The 94230 installs inline on the inlet side of your freshwater pump. During camping season, the handle points toward your normal water source and the valve is completely out of the way. When it's time to winterize, you flip the handle, drop the pickup tube into a bottle of RV antifreeze, and run your pump -- antifreeze reaches every faucet, toilet, and water line in your rig without disassembling a single fitting.
This valve is manufactured for Thetford by B&B Molders (B&B part number 601-008-94230) and carries a Limited Lifetime Manufacturer Warranty. Factory leak testing ensures zero leakage before the valve ever ships.
The clearly identified operating handle makes switching between freshwater and antifreeze fast and intuitive -- no tools required at the valve itself.
Every unit is pressure tested at the factory before shipment, so you can trust a leak-free installation from day one.
Manufactured domestically to Thetford quality standards, with materials suited for potable-water and antifreeze compatibility.
Backed by Thetford's Limited Lifetime Manufacturer Warranty for long-term peace of mind on a component you'll use every season.
The diverter valve installs on the suction side of your 12V water pump. Most RV freshwater pumps use standard 1/2-inch barb or threaded inlet fittings -- the 94230 is designed to fit into this line with minimal modification. Once installed, your annual winterization routine becomes:
In spring, flip the handle back to the freshwater position, flush the lines thoroughly, and you're ready to camp.
