Leaking Toilet supply line

[Tkaufman50]

HI, We just picked up our new 312MLS Sprinter and I have a drip at the waterline connection to the toilet. I've tried to tighten it some being careful not to over tighten being that it's a plastic part. We have it at an RV Park about 160 miles away for the summer and I don't really want to haul it into Camping World for them to have it for two weeks. Any ideas on an easy fix? I'm also thinking we want to upgrade to a porcelain Dometic toilet so now might be a good time to make the switch.

Thanks, Tony

Welcome to the forum
If the leak is at the supply line fitting, then the cone washer inside has failed. Since it’s 1/2” pex, you can probably get a new washer at any big box hardware store. If your near any RV parts store, it is a very common part and cost is less than 50 cents.
