Water ingress into caravan

‘Hello C C members, We have used our caravan frequently over the past few months, unfortunately during our last outing the water pump intake on the Truma unit failed causing water to flood the interior of the caravan around the intake unit, at this time we were on a serviced pitch and didn’t notice until we were ready to make up the beds. Has any other C C member other than me experienced this problem? The unit had cracked on the bottom side of the intake. I was informed by the retailer they had sold these units previously because of the same problem.’
