Hi all, away on hols & have problem with onboard tank not supplying taps. Tank has filled as normal from aquaroll but that's as far as it goes. Only got water at taps by turning off onboard tank and then drawing water direct from aquaroll. Thought it was pressure switch, no swift dealers in the area so couldn't replace the comet one so put a whale one on & still doesn't work. Flojet failure ?? Any ideas much appreciated. Regards Sir Roger
