The Comet pump, made in Germany, is a quality product with a superior specification to the Whale pump being replaced (20 litres/min as opposed to the Whale’s 16 litres/min flow capacity). It also has a 1.1 bar pressure rating. I don’t know what some of the parts cost to Whale but as an ex electronics iengineer I guess the IC a few pounds and a seals, non return valve kit etc similar money. It could be the pump but at this stage I am unwilling to spend on a new one to test. I should add, I know I am only talking about 1 dealer, but they have a ‘good’ name around here. I also feel that I read lots of similar reports on different forums. I note from some earlier posts that some of you have found Whale very helpful even to the extent of them sending replacement parts to try to solve issues.

In the end as I was getting no where and more frustrated, I ended the call suggesting I would seek guidance from elsewhere. Push new cable through guide tube; mark where it emerges.

In normal use, the water surrounding the pump in the container serves to keep it cool while operating. However, once the water container runs dry, if the situation hasn’t been noted and rectified, the pump can continue running, becoming progressively hotter until terminal failure occurs.

I’ve a 2020 year Coachman VIP Caravan fitted with the Whale submersible high flow pump (in bowser Type) and the IC controller within the van. It is very bad form to criticize a company on a forum when the company does not have the opportunity to respond in a timely manner, and only one side of the communication is available. I explained that normally on opening a tap the water flow would be good for a few seconds then slow then speed up again. To me this suggested the IC was controlling the voltage to the pump which was part of its surge prevention facility. The reply I received was no it doesn’t do that it’s your non return valve. On this you have my sympathy. When new with guarantee niggles it cost me much money and time in what seemed like continually returning my van. With the odd thing I got telephone help from a technician which was fine. For other things it was a frustrating experience. First of all, I have asked Whale Support for assistance but at the time of writing they have not responded,. This is probably due to Covid 19. I then decided meanwhile I would ask the forum. so here goes.One of the things that upset me most, was that there seemed to be zero realisation that, by not proBut viding a comprehensive service it absorbed my time, reduced my usage and enjoyment and was a cost. It was also inefficient for them and did not engender customer loyalty. Inside connector showing spade connectors. Note the polarity. Inside connector showing spade connectors. Note the polarity
