Hi we have a new (2007) Adria Altea 462PS and since we bought there has been a starnge noise coming from the water pump which happens every 20 mins or so which is quite annoying during the night. It sounds like air is escaping the system back into the aqua roll. Our van has a micro switch system not a pressure system.
One obvious solution is to unplug the pump during the night but this isn't ideal as toilet flush operated off the water system.
The system is always bled ok and taps are all working and shutting off fine.
Any solutions or advice would be gratefully received. The van will be going for a service later in summer with the dealer but to take the van out of storeage to get this looked at would be a real pain for something so minor.
