Hello
Have just started to commission a new to us 1992 Hymer S 670, and are at the water system cleaning and filling stage.
On re-connecting the Fiamma Aqua 8 (10LPM) pump after leaving disconnected for the winter I ran the pump dry for 3 - 4 seconds to check on operation (researched it can run dry without problem). It ran very quietly and instantly.
Half filled tank with water and ran for bursts of 10 - 15 seconds with hot and cold taps open, at that point it was sounding like a small Kango hammer.
On re-fitting the pump I took trouble to make sure the 4 rubber feet were not compressed to enable the sound and vibration insulation, so a rigid connection to the MH body is not the problem.
Once all taps supplied water without air just ran the taps for short bursts to listen to the pump, very noisy but functioning. The pump runs for 20 - 30 seconds once the tap is off even though a Fiamma accumulator is fitted, think that is too long?
Do we have a knackered pump, a problem I can't see, or is this normal for a ' whisper qiete ' pump?
Any help appreciated
