Probably everyone knows this except me, but just in case!
We are away in our new (to us) caravan and the on board Ultraflow water pump refused to turn off and air was getting in to system. Went through all the possibilities: looked for leaks, inlet hose split or adrift from assembly. Checked the O rings were not split. Started worrying about the pump diaphragm, whole pump, non-return valve and how to get it fixed while away without buying expensive parts which may or may not fix the problem. Decided to try a spare O ring on the intake hose assembly - cured!
Looking more closely, although intact the O rings are hard and have lost their elasticity and so are no longer sealing. Off tomorrow to buy a replacement for the second one and some spares.
Out of curiosity, why have the manufacturers stopped fitting filters?
