Place a washcloth on the faucet aerator at the bottom of the faucet where water exits into the sink.
Place adjustable pliers on the faucet aerator and turn it counterclockwise to loosen.
Pull the aerator straight down to detach it from the faucet.
Turn the aerator upside down and make certain that the screen and rubber washer are inside the tip.
Place a small piece of tape over the opening in the aerator to hold the washer and screen in place. Set the aerator aside.
Hold the faucet adapter up to the end of the faucet and screw it on in the aerator's position. Turn the adapter clockwise and tighten it completely.
Screw a garden hose onto the adapter in the same manner as an outside water faucet. Turn the hose clockwise to tighten fully on the RV sink. The hose has a female end that fits onto the threads of the faucet adapter's male fitting.
Turn the RV sink on and direct the loose end of the hose at any area to obtain water.
