water over flow

Well we are leaving next Monday for Indiana (one week from today)
We had just parked the camper by the house 2 days ago.
We went out today, the shower gray water had overflown and the carpet
in the bed room in the 5th wheel is flooded.
What is the best thing to do to clean it?

(and to avoid it happening again) grrrrrrrrrr

Use a shop vac with water attachment to remove excess water.
Clean with standard carpet cleaning equipment.

What caused the water to overflow? Is the unit connected to 'city water', perhaps there is a leaky faucet in the galley or in the bathroom.
