Please choose the correct ending to complete the given sentence: Home and Garden: [header] How to remove a tub faucet [title] Look on the underside of the faucet to locate the screw. [step] Slip-on spouts will have a set screw under the spout, near the tub wall. The set screw secures the spout onto the water supply pipe.

Ending1: Feel and look at the faucet for a screw hole on the underside of it. If there is no screw under your faucet, you probably have a screw-on faucet. Ending2: [title] Use a small razor blade (kg) or any other flat edge tool to mark a notch or recess on the underside of the spout. [step] An unused knife will work for removing the screw head from the tub. Ending3: [title] Remove it with a blunt, easily removed screwdriver. [step] If a screw is underwater, do not attempt to remove it with a knife or a heavy object. Ending4: This screws the faucet into place. If your plumbing kit does not have a set screw, you should still twist a corner of the faucet to take it out.
