Frequently Asked Questions

How do I know if my supply hose needs replacement?
Look for visible cracks, splits, or discoloration in the hose. If your toilet bowl isn't filling properly or you notice water pooling under the toilet, the supply hose may be compromised. Any kinks or hardening indicate it's time to replace.
Will this hose fit my Dometic toilet model?
This 9.75" kit is designed for standard Dometic gravity-flush and vacuum toilet models. Check your toilet's documentation or compare the hose length to confirm compatibility. If unsure, contact our expert support team with your RV model and toilet type.
Is installation difficult?
No. The pre-assembled hose features simple push-fit connectors that connect to your freshwater inlet valve and toilet bowl inlet. Most RV owners complete the swap in under 10 minutes without special tools.
