Hi, the Dometic toilet in our Lunar is leaking pink flush between the porcelain bowl and the plasic cowl. It seems that that when flushing some of the pink is getting between the 2 bowls and finding it's way out via the front valve handle. Anyone else had this? Stripped it down and cleaned the rubber seal but seems not to have cured it. Anyone know the warranty? Out in France for a few more weeks and as it's a trickle and not a flood can easily manage.
