Frequently Asked Questions

Q: Will this hose kit fit my RV's water inlet?
A: Yes, if your RV has a standard 1/2" NPT male water inlet connection. This is the most common freshwater connection on Dometic-equipped RVs. Check your owner's manual or existing hose fitting to confirm compatibility.

Q: Can I use this for both fresh water fill and gray water drain?
A: No, this kit is specifically designed for freshwater supply only. Using it for drain applications may cause backflow and contamination. Always use separate hoses for fresh water inlet and waste water outlets.

Q: How often should I replace my freshwater supply hose?
A: Replace your hose if you notice cracks, leaks, discoloration, or a musty smell. Even without visible damage, replace hoses every 3-5 years as UV exposure and temperature cycling degrade rubber over time.
