The water tank was not supplied with the correct fittings as per the listing on their website. I have tried twice to get them to sort it out and both times they have fobbed me off saying they have referred the issue to the manufacturer. I'm a couple of months down the road and still no resolution so I've sorted the issue myself. Great item but very poor customer service. I would not use them again as customer service is as important as product quality if not more so.
