How to Replace a Bathtub Spout - The HomeDepot

Replacing a corroded bathtub spout can give an immediate fresh new look to your tub, fortunately, it's one of the easiest of plumbing chores.

You'll need water pump, pliers, a sturdy screwdriver, Teflon tape, and perhaps a set of hex wrenches, before you purchase the new spout, it's best to remove the old one, take the old part with you to the Home Depot, and use it for comparison, that way you'll get a new one, that's a perfect fit for the connection pipe, your existing spout may be attached by set screw or by threads, first check on the underside for a hexagonal set screw, use a hex wrench sometimes called an allen wrench to loosen the set screw completely, pull the spout free of the wall, if there is no set screw, then your spout is the screw on type, if it's not in place, too tightly, you may be able to unscrew it by hand, if it's on too tight, just insert a screwdriver into the spout opening, and use it as a lever to loosen the spout until you can rotate it off with the spout removed, measure the length for the connection pipe protruding from the wall, it usually will be either about six inches in length or will barely protrude from the wall, whichever it is, purchase the new spout of the same size and type for a set screw spout, simply slip it into place and tighten the set screw underneath.

For a threaded spout, first wrap some Teflon tape around the threads of the connection pipe, then twist the spout onto the pipe in a clockwise motion, use water pump pliers to tighten it, note that the jaws of the pliers are covered with tape to prevent scratching the spout.
