If the hose is "frozen solid" where you can not disconnect it at the tank discharge end you have a larger issue than just the hose. Can't imagine a dripping faucet would ice up the waste hose solid. That would be a lot of water. I would try a heat tape around the end closest to the tank first. Let it run all day then give it a go. I've used a strap wrench on stubborn fittings before with success.
