Grey is the colour. Gray is the surname. 😄
We also had problems similar to this with our black and grey tanks/valve handles. Our dealer gave us the supplementary valve that twists on to the end of your drain outlet. Now I simply attach the clear plastic fitting and then the regular hose to the supplementary valve and I can see when everything is running clear. We also had the dealer fix the factory fitted valves but due to the length of run on the pipes we still had some waste water that collects at the outlet valve after we had travelled a short distance. The twist on valve has cured that.
Something else to bear in mind (you may have known or thought about this already) but on the 38FL, your shower drains in to the galley tank. Only your bathroom sink and the washing machine (if you have one fitted) drains into the other tank. On ours I believe that tank 1 is the washing machine/sink while grey 2 is the galley/shower. I always leave our grey tanks open when parked up at a site. Never had any problems with sewer gasses coming back up but I do tend to create a trap in the flexible sewer pipe which may help.
I hope you enjoy your 38FL as much as we enjoy ours.
