I'd consider removing all of the poly line and the drain valve too and replace with upgraded braided line. I just did this on my Landmark based on number of leaks others had experienced with their rigs over time. Took ~30 min to remove the fridge, pull the new line through, and move fridge back into place.
Put down 2 x 4 with plywood and rolled the fridge right out of the slide onto the makeshift deck. Made it super simple to get it back into the slide. I was the only one moving the refrigerator. Be sure to remove screws at the base of the refrigerator behind the kick plate and the fascia and framing on top of the refrigerator too. It will roll right out once you have all the screws removed.
I used a 20' and 10' piece of braided icemaker lines to run from the back of the fridge all the way back to the shutoff valve under the sink. Taped the braided line onto the end of the poly under the slide to pull through bottom of the slide to the refrigerator to start. Then I did same on poly through the frame to valve under the sink. Only hole I had to work on to get the fitting through was the floor of the slide up to the refrigerator. Difficult area too because the water line and the propane line run through the same opening...so be careful if you have to ream it out.
Drain valve was a waste IMHO, so I didn't replace it. I blow out the lines with the compressor whenever I need to have it empty.
On a recent camping trip after setting up I noticed water on top of my left rear stabilizing pad. I looked under the frame and there is a slight water drip coming from the drain valve on the ice maker water line. The water is coming from around the rubber seal where the line goes into the valve.
Can I replace the rubber seal or do I have o replace the entire valve? Do I also have to replace the entire waterline in order to get it through the valve or can I splice in w I need?
Any advice or help would be appreciated-
