Frequently Asked Questions

Q: Will this adapter work with my RV's fresh water system?
A: Yes. This PVC adapter is rated for fresh water, grey water, and black water applications in most Dometic plumbing systems. Always verify compatibility with your specific RV model before installation.

Q: How do I connect the hose barb side?
A: Slide your tubing onto the barbed end and secure it with a hose clamp. The barbs grip the tubing and prevent slipping under normal water pressure.

Q: Can I use this to replace a metal adapter?
A: Yes. This PVC adapter is a direct replacement for OEM Dometic metal or PVC adapters with matching 0.75" FPT x 0.75" HB dimensions. PVC offers excellent corrosion resistance in RV environments.
