  Bathtub drains can suffer from a number of different problems that prevent the water from flowing correctly. Slow or stopped drainage in a bathtub leads to problems with keeping the tub clean or even using the tub. Identifying the issues related to bathtub drains is the first step in solving them. There are several how-to books that include bathtub drain issues.
  
  

Clogs

• Most bathtub clogs are caused by hair. As you wash your hair, loose hair becomes clogged in the drain and prevents the water from flowing freely. Bits of soap can also cause the hair to mat, making it even more difficult for the water to pass through. The hair can be removed by reaching down with your fingers, or by unbending a coat hanger to use to dislodge the clog and drag the hair back up. If those methods prove ineffective, use a plunger on the drain the same way that you would use it on a toilet. The suction will dislodge the clog and allow you to bring it back up. To prevent hair from going down the drain, brush your hair before taking a shower, and remove hair from the tub immediately after showering.
  
  

Leaks

• Bathtub drain leaks allow water to enter the space near the pipes, and it is important that they be taken care of as soon as they are noticed. A common cause of bathtub drain leaks is aging plumber putty near the drain lip. When the putty ages or cracks, the seal of the bathtub drain loosens. This allows water to get into the area surrounding the pipe. If you notice a bathroom drain leak, it is wise to call a professional to do a thorough check of the piping in the area, as the water may have damaged other areas.
  
  

Frozen Pipes

• In very cold weather, water can freeze in the pipes of your bathtub drain. Not only will this clog the drain, the frozen water swells, putting more pressure on the pipes. If left untreated or if the temperature drops suddenly, this can lead to the pipes exploding and flooding the home. Prevent the pipes from freezing by wrapping any outdoor pipes or pipes in unheated indoor spaces with fam rubber or insulation.
