Jabsco pump running on

Glad you sorted it.

Thanks, both! I'll take a look this weekend I think. Following advice from Jabsco, it's also possible that the cables are too thin and voltage is low down that end of the boat too. If you have any tips on cleaning the filters (without flooding the boat...!), I'd be very grateful.

My pump does the same occasionally My batteries need replacing so I'm not going to worry about it.

The London marathon's coming up. If Jabsco is so good at running, buy him some pumps and enter him.

There should be an isolation valve close to the water tank but it may nit have been moved in years so a bit of  force may be needed to close it. If you have any rubber/plastic hose either side of the pump then a pair of car brake hose claps will probably desolate the pump.
