Hi please can anyone help when I flush the toilet in our Lunar Cosmos it flushes fine but when I release the flush button the pump stops but flush water continues to trickle into the bowl for quite some time after

    Errr, mmm, never heard of that one. It's got to be something to do with the tube leading to the flush I would say. When you flush, does the flush start immediately or is there a delay before you see the water??

    Hi thanks bit of a strange one yes flush water comes through as soon as you press the button, only thing I can think it could be is some kind of syphoning action

    Our Dometic toilet does this frequently!  We have found it half full on one occasion.  It only seems to do this when the flush tank has been fully filled; as soon as some water has been used it then behaves correctly.

    When we had the Lunar clubman our flush ceased to work, dealer tried everything, in the end dometic sent a new loom, which cured the problem. It needed the toilet to be removed to fix it so why it was out l insisted on the uprated pump which they did after l had said the original was not fit for purpose and quoted heath issues. The flush was far better on the uprated pump
