Mineral deposits may create clogs.

Bathtub faucet pipes rarely ever get clogged, but when they do you know it. Small trickles of water may come out of the spout, or none at all. Excessive buildup of minerals in the pipe may be the cause, or sediment from the water in your area. Either way, the clog must be removed so you can enjoy a relaxing bath. Luckily, removing the spout from a tub, as well as clearing out the clog, does not need professional guidance.

Step 2

Inspect the underside of the spout for an Allen screw. Turn the screw with an Allen wrench, if present, and slide the spout off the unit. Unscrew the spout by gripping firmly and turning counterclockwise if no is screw present.


Step 3

Insert an internal pipe wrench into the pipe coming out of the wall and turn it counterclockwise with a wrench. Remove the pipe and inspect it for clogs by holding it to the light and looking through. Stick a stiff wire brush into the pipe to remove the clog then replace. Reinsert the pipe if no clog is present.

Step 4

Insert the end of a thin closet auger into the end of the pipe. Turn the handle of the auger to extend it into the pipe until you feel it hit the clog. Reverse the direction and reel the auger in a few feet, then move it forward again. Continue until the clog is broken free.

Step 5

Replace the spout in the reverse order of its removal. Turn on the water supply to the bathroom.
