I use this anti syphon valve all the time for backflushing my black tank in my fifth wheel. Just buying a new one to replace old one. I've use E trailer for years for other purchases and your customer service is second to none and I appreciate That and you have professionals that are very knowledgeable and helpful about your Products you sell and I appreciate that.

etrailer service is excellent. These back flow restrictors were received quickly. The are just the product I was looking for. Connects to both ends of a standard water hose. 5 Stars.

Backflow restrictors works perfectly. I dont even know it is there on the hose.

Do you have a question about this Accessories and Part?

Are Any Additional Fittings Needed for the Valterra Hydroflush # F02-4100

Recommended Backflow Preventer for 3/4 Inch Spigot
We don't carry the 3/4 inch pvc connectors, but we do have the Camco RV Fresh Water System Backflow Preventer - 3/4" Diameter - MPT x FPT - Brass # CAM23402 designed for that same function. The Replacement Anti-Siphon Valve for Valterra HydroFlush and Flush King Reverse Flush Valves - Plastic # A01-0141VP may technically be used for that purpose as long as you are only ever using it for that purpose.
