Report "We have a rain water tank hooked up to a Orange HT100 pump. The pump is continually running but there isn't much water entering the toilet. After the toilet is filled the pump is still going. There is not failure light showing on the pump. The water entering the toilet was starting to look discoloured. We thought that it was from the bottom of the tank. We had a look at the pump and noticed that there was a slight leak from the top connection of the pump. Not sure if this could be the problem. Can you please give us some advice Thanks Clare"
