That's an extraordinary bit of luck. You can check it easily then. >What I have noticed is that for a number of > years there has been a small pocket of air at the top of the clear plastic > filter housing that is screwed on to the pump inlet at the same level as the > pump, this 'bubble' stays constant, pump on or off, is that a problem > perhaps? No probs. You cannot rid the system of air completely in pockets caused by the top of something such as a filter housing. That will not be your problem. Look for air bubbles in your clear pipe as a first step. > I did not mention that the pump and accumulator are about 30 feet apart and > I know that it is advisable to have them adjacent when space permits. > There isn't room to relocate the accumulator, but I could possibly move the > pump to under the sink next to the accumulator. I wouldn't bother. While it may be desirable to have them adjacent it hasn't caused you a problem in the past so why should it have suddenly started to cause a problem now?. I'm pretty sure the clue lies in something that has happened over-winter or during de-winterising. Roger
