You will find that some submersible pumps have ‘Do not run dry’ printed on them by way of a warning.
Problems from the outset, the IC hadn’t been calibrated by the dealer or whoever so having been either near scalded or frozen in the shower I found the issue and re calibrated the pump/IC. 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. 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. Of course, you can always use a Whale pump if you prefer, and the procedure for replacement will remain exactly the same.

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. 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.
