Water pump failure on site now - help!

Hoping for a quick response as on site right now….

the water pump 12v fuse has blown, and did so again on replacement. On checking the submersible pump (plugs into inlet on side of caravan), it seems to me the tiny rotating blades at the end of the submerged (in the water barrel) pump are stiff. I can turn them, but there seems a lot of resistance. Having never had this problem before, is this correct action, or should they spin freely? Would their stiffness have caused the fuse to blow?

If they should spin freely, easy solution is to buy a new pump. But other thoughts welcome.

thanks

Ian

I must admit, that even though I'm lucky enough to have a frost proof on-board tank I carry a spare pump. I think the drop in type I need are only about £15/20.

I had a spare and used it on our last trip. It's an onboard tank and the problem was nothing todo with frost or cold. This thread reminds me to replace the spare.

We have always carried a spare ,which is a big upside with most submersible pumps much cheaper and far easier to replace ,than the noisyer inboard typecool

Do any manufacturers still design vans for 'outside' pumps these days? These toy town ones on the length of a hose always seem a bit flimsy to me.

Not at all, ours was purchased in 2008 when van was new, replaced last year, bought the Whale x 2 which is Truma compatible, but looks to be better engineered. You can buy them for approx £65 and dont have to faff around to fit, bit of vaseline on the contacts and away you go laughing

Perhaps you could carefully dismantle the faulty pump to find the cause? It would be good to know if it can easily be rectified should another member have the same problem.  It might be lack of lubrication in motor.  And if you fix it you save the £59 for a spare.

I always carry a spare pump, and when I changed van 3 years ago needed a different pump. Found one on EBay for about £30. Been carried as a spare and never used, worth a look.
