I had an airlock in my Autoquest180,I managed to clear it after 5 hours, however, the shower mixer pipe blew off, but, it has gone under the vanity unit on top of the wheel arch, but, there is no way of getting to it that I can see, I have taken the sink unit off, but, the hole that is left into the wheel arch is not big enough to have a look into to retrieve the other end? The only way I can see of getting to it, is to remove the whole toilet and bathroom floor? Can anyone help please???
