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

You probably won't get the quick response you're expecting at seven in the morning ITGundecided. As above could be cold weather. Try taking the pump indoors and pour a kettle of hot water on each end, if that doesn't work I'd say new pump. You could always see if you have a neighbour with a similar pump who'd lend it to you for five minutes just to check? 

If there isn't a caravan shop nearby, get one off of amazon as they always deliver next day.

Check with site staff if on a club site to ensure they will accept amazon parcels

Highly likely a frozen pump. Cure is to take it in at night, put back in morning. Lagging your barrel, get it up off the ground, and that will help. Old trick is to use an unwanted old coat. Put the pipe down the sleeve, wrap the barrel in the jacket. Fingers crossed for you that’s all it is🤞

Amazon uses W3W for precise deliveries. I’ve had an order delivered 200miles from my home to a sainsburys car park. It works, Amazon works well remotely JK👍🏻

Thanks all.

As I had to go out, I didn’t get to resolve this until this afternoon. Replaced the fuse again but I doubted if the cause was ice, as although there was a ground frost this morning, the water in the barrel was not frozen, but I did follow advice to immerse the pump in warm water - no different. The (temporary relief) warden did have a used identical pump, but couldn’t say if it worked or not. So I tried it, and it didn’t work, but interestingly did not blow the fuse. 
A fellow camper I approached of course had a pump of a different make and fitting, and in the cold early dusk, not too many others strolling around who I could ask. This led me to take a risk to pop down 5 miles to the nearest caravan dealer who supplied a new pump for £59. He did assess the blades in my faulty one as tighter than they should be.
Fitted it, and bingo, first time ok. So don’t know what the underlying problem was, but at least we have running warm water again.

Thanks again all.

Ian, that's good to know.  If you take my advice, the next thing I'd do, is pop back to that dealer and buy another pump!  Yes, I know it's another £59 - but you will have the peace of mind that if it should happen again, you've got a spare to hand.  I've always carried a spare because although you can get by if the pump fails, it's a bloomin' nuisance and it's always going to happen at the most inconvenient timeundecided

That way,  you'll make sure it never fails againsmile

Glad you got your problem sorted eventually Ian.  They are flakey pieces of kit, water pumps,  we have one that works fine every trip, we also have a spare that works after fiddling with the pressure valve no reason why as nothing changes.  Anyway, as Richardandros suggests always carry a spare.
