Sounds bad but you might be alright.
A few years ago my hozelock connector came adrift from the water tank and started pumping out water into the back of the van and then into the footwells, while I was driving.

I had to pull over and try and scoop most of the water out best I could.

When I got home I used a carpet cleaning machine to suck all the water out from the carpets, it worked well and all was ok.
If you are having a day off try and get as much water out as you can and if van is in a safe place leave the windows or doors open to help dry.
Good luck.
