Hi,
over in France at tail-end of a long rugby World Cup trip, and now no water in caravan. Here’s the detail…
The pump is an external Truma type, which sits in the water barrel and connects to caravan via a ‘pistol’ type fitting which plugs into the caravan wall socket. It’s been fine for all the trip, although on the last site we had main water hook up, so the pump was not in use.
Now it runs, but fails to pump water in. I know it pumps water, as holding an 9v battery to the terminals on the pistol, does pull water through. After extensive investigation, including separating each part of the inlet process, I now know the water fails to get through the actual wall socket. A nipple on the pistol should push and open a rubber seal in the socket, to allow water through. That’s where it fails.
So I reckon only two possibilities.
1. although the pump runs, is it doing so at too-low pressure to hold the rubber seal open?
2. the rubber seal itself is faulty in some way?
I know I may not get a spare part in France if needed, and with only 5 nights left, we may have to get used to a jug for everything, but interested to see if any other ideas or experiences of anything similar, and why/how it happened?
Thanks for any help.
