I guess it will depend on the type of valve, may just be something stuck in it, poke something up when emptying next

On our Hymer we had a gate valve operated by a wire, bloody useless idea, luckily ours failed fully open and I fitted a new valve at end of pipe

Hi I’m afraid there is no quick fix on those, is it the type with the blue button on the side and lever on top.
The best thing to try is to activate the dump valve manually just in case there is a bit of lime scale stopping it seating properly.

A soaking in hot white vinegar, preferably white wine vinegar often does the trick, should get rid of any calcium build up

There's a motorhome sales and service place near you that might have spares:

Caravanas Sangar

Lat.: 37° 39' 35" N
Long.: 0° 54' 14" W

Easy access just off motorway. We've used them a few times when staying in that area.
