Normally I always streilise the onboard water tank, aquaroll & the whole system two days before we go away, last week we went away at short notice & I decided I would run the milton throughout the system as we were setting up & then flush it through, well I must not have flushed it for long enough ( X 3 aquarolls full ) as it could still be slightly smelled when running the taps, funny though the next day after the tank was emptied & refilled the smell had gone........
Could this be some of the problem ???
