How hard is it to reach the valve itself?
You could get a replacement from amazon and change it with just small wrench and maybe pliers. Literally a 5 min job ASSUMING THE TANK IS EMPTY!!!
I don't know about the cable connection but you could change the valve and scramble under there to pull the handle for now when you need to dump. https://www.amazon.com/Valterra-T100...2-d605505c9d1e
