Thanks both, I will be tackling this next week Tuesday when I'm back at the boat so will update then.

Thanks Tracey, so even though the inlet filter was pretty clear, muck could of still got through the filter and into the pump?

Very likely! What would be the best way to inspect/clean the pump and pressure switch?

Its 6 seconds with water running then taps kick in. I have an accumulator fitted but prior to the water tank emptying the pump would cut in and cut out almost instantly. The other issue is the change in noise of the pump. Its now more of a mid/lower range chug,chug,chug rather then the higher pitch hummm

Hi All, A couple of days ago my water tank was left to fully empty causing air to be drawn into the system. I have now fully filled up the water tank and have ran the taps in the bathroom, kitchen, shower and toilet flush. This flushed out a nice bit of rusty water along with the air in the system. The only thing now is the pump hasn't returned to its normal operation. Its taking about 6 seconds for the pump to kick when an outlet is opened and again around 6 seconds to stop after outlet has been closed. I have checked the inlet filter from the tank to the pump and seem to be pretty clean. I assume there is still air in the system somewhere which is messing with the system pressure. Is this just a case of checking all points in the system and trying to bleed the air where i can? I.e undo a few nuts here and there to see if there is any trapped air? The taps and outlets are not spluttering anymore and flow seems to be pretty normal. The pumps is running with a lower hum then its usual higher pitch noise. Any suggestions would be much appreciated as will be tackling this in the coming days.
