We took our 2008 Jayco PUP 1006 camper out this weekend for the first time this year. I thought I had fixed the sink before putting it up last year, but it ended up leaking still. The original pvc piece that goes from the sink hot water knob to the water line broke last year and I was not able to find the exact replacement. I found something I thought would work, but it still leaks. In the picture, the attachment without the metal connector is the one that leaks. Can anyone let me know how I can find this exact part? My other thought is that we don't use the hot water heater, so I can simply cap this line under our seat and that should be good enough. Is that a good/bad idea?
