Cold weather, water, what to do..

We're out camping at a KOA. It's supposed to be 25-26 degrees in the morning. The campground sent out a text saying disconnect the hose and leave their water bib dripping or, let the water drip in the RV. My plan is to disconnect the hose and let their faucet drip and use the on-board tank for water till things warm back up. My question is, if I let my faucet drip will it not fill up the grey tank and then over-fill it? I'd prefer to leave the hose connected and let my faucet drip. But, having a crisis in the wee hours does not appeal to me whatsoever.

Leaving the gray tank valve open and a faucet dripping inside would cause an ice dam in your stinky slinky - don't do it. Disconnecting the hose and letting their faucet drip while running off your fresh tank is the proper approach.

I do not know why your gray tank would overfill if you leave the valve to the tank open, assuming you have full hook-ups. If you do not have sewer, simply fill fresh water tank and use it until the temps rise above freezing. Don't forget to put your water hose in your storage so it does not freeze as well.

First off there is NO overflow on waste tanks ....it's WASTE and should be dumped according to local laws/restrictions
Grey could backup into shower
(Black could backup into toilet piping or even Vent line)
Only 'overflow' could happen if tanks were overfilled and they leaked into your underbelly

I ONLY use the fresh water tank/pump
Both are enclosed/heated etc ....I never leave a faucet dripping

IF CG wants there supply bibb dripping that's on them --- so just disconnect your hose, Drain it, Stow it and crack their bibb just enough to drip
