I have a 2017 Hymer Nova caravan with a 12 volt Comet VIP Plus water pump as well as a separate in board water pump when using an in board water tank. In the last 5 years I have had to replace the external water pump 3 times. They continue to function but at a much reduced flow rate reducing the tap flow to just a trickle. Changing to the in board tank restores normal flow rate.
We average about 6 weeks caravanning a year which is hardly excessive. The specification of the Comet pump is quite powerful (1.1 bar - 20 l per min). Any ideas why 3 failures? Is there a better more powerful and especially durable alternative. I am able to swap the connectors to a different model if required. I have even wondered if installing an in board pump would be better. Is there a danger to the taps in fitting a more powerful pump?
Many thanks.
