There was a leak where the float valve went into the tank and it has made some of the artex fall off the ceiling. Wife is not happy. Another job to do. It is not too bad and I think that I should be able to repair it.
I have added an extra filter going into the main tank. I used a plastic container with some filter media in it. Not sure if it is going to work but did not cost me anything as it was just going in the bin.
I have got a manual timer that just runs during the day. Will see how this works out. Still lots more to do.
