Can D&W Inc. Spray-Port RV Exterior Hose Hookup Backflow Preventer Be Replaced With Brass
Updated 03/04/2026 | Published 02/07/2026
Question:
A backflow preventer on the exterior spray port on my RV cracked when we are traveling during the winter due to freezing conditions. I just ordered the DandW Inc. Spray-Port RV Exterior Hose Hookup from you and I read that I can replace the PVC backflow preventer with a brass one. Is this true and if so, is it recommended?

Hi Rick; the backflow preventer can be replaced with a brass one on the # PF147006, although we don't have any parts that would allow you to do it. That is something you would have to pick up locally. I'm sure it would be more durable so it would be a good idea if you're concerned about the cracking you just experienced.
