Frequently Asked Questions
Q: Will this swivel adapter work with both my fresh water and gray water systems?
A: Yes, this Dometic adapter is designed for use with both fresh water supply lines and waste water systems. The swivel design and durable construction handle the demands of either application.
Q: What does the swivel feature do, and why do I need it?
