Bathtubs

A clogged bathtub trap is a bigger problem to fix, but not impossible. Unfortunately, it does mean some extra work.

Before you assume that it is the trap you want to make sure that you to check a couple of other things. Two common problems with bathtub drains are hair in the strainer and a stuck or broken pop-up assembly. See the articles 'Fixing Bathtub Drain Clogs' and 'Repairing Bathtub Drain Stoppers', for more information and instructions.

Locating a Bathtub Trap

Bathtub drains have traps to keep sewer gas from getting into the house. For a bathtub that has a basement or crawl space below it you may be able to see it from below. When the house is built on a slab or for an upstairs bathtub, there should be an access panel on the opposite side of the wall. This might be in a closet or bedroom wall in the room that is on the other side of the drain end of the tub.

Unfortunately, this trap differs from the ones under your sinks. Usually the fitting are glued or soldered together and do not come apart. For a clog in the trap you will have to run a snake through it. I do not recommend drain cleaners. Very bad chemicals that are not environmentally friendly is one reason. The other is that they don't work that well.

Bathtub Trap Clean Out

Some bathroom traps have a clean out plug on them. This a nice feature and makes cleaning out the trap much easier. The clean out plug will be located at the bottom of the trap. Before you remove the plug you want to have a pail underneath that will catch the water.

If the bathtub is full of water, it is not a good idea to use the clean out plug. All of the water in the tub my come gushing out. With a full bathtub, you want to snake out the trap, see below.

Using a Snake On a Bathtub Trap

The bathtub drain is usually in close proximity to the larger main line that the toilet is hooked to. This means that you don't need a long snake. Generally less than 25' in length. It should be a small snake, one that is suitable for a sink line.

Accessing the Snake Entrance

Do Not try to snake a bathtub drain through the drain in the bottom of the tub. There is no way to control which way the snake will go. In addition, the strainer opening is too restrictive to get a snake through, it will bind the snake and may cause it to twist.

Do Not try to snake a bath tub drain without removing the pop-up assembly. The snake will catch on the assembly and may ruin the linkage, the snake or both.

Take off the cover for the overflow and remove the linkage and plunger for the stopper. This is normally the spot the has the control for the drain, either a lever or a dial that causes the drain to operate.

Using the Snake

Run the snake down through the opening. The toughest part will getting through the trap. Apply pressure and turn the snake until it twists through the trap. Try to judge the distance you need to go to get to the stack behind the toilet.

Run the snake through a couple of times. If the tub has water in it, the draining of said water is a sure sign you have been successful.

Checking the Drain

If you do not have water in the tub, try running water into the tub and see if it is draining. If so, put the pop-up assembly back in and fill the tub part way. Let it drain out with the water running.

Water Running Out Slowly

If you have snaked the drain and made sure the 'Bathtub Linkage' is working correcly, then you may still have some issues at the strainer, see the article 'Bathtub Drain Clogged' for information and instructions.

Summary

Got it? Water going down? Great this clogged bathtub drain problem is solved.

Many bathtubs have a metal lever at the bathtub overflow that controls the drain. There is a metal plunger that is connected to the handle by linkage. Sometimes the pins that hold the linkage together can corrode and break. This will cause the plunger to stay in the closed position. Try the handle and see if it feels like it is controlling something. When it moves freely without any resistance, it is likely broken.

Remove the screws that hold the overflow cover in place. When you pull the cover away the linkage should be attached to it. If it is, check the plunger and make sure it is moving up and down the vertical tube freely. Has the linkage separated from the lever. Yes, then you will have to try and fish the linkage out with a pair of pliers or a coat hanger. The linkage is held together with cotter pins. You will have to obtain some replacements for the one that has broken.

Assemble the linkage and put making sure it is securely attached to the handle. Put it back into the vertical tube and put the screws back into the cover plate. Try the handle and see if the stopper moves up and down freely.

There are a couple of places a bathtub drain can leak. One is around the drain. The other place is where the vertical overflow tube and the horizontal drain come together.

Leaking Drain Pipes

There are some compression fittings there, similar to the ones under your kitchen sink. You should be able to get to the compression fittings through and access door or from the basement.

Just like the sink drain fittings, these have washers in them. You can try to tighten them and it may stop the leak. Replace the washers when it will not stop leaking. They should be 1 1/2", she same as a kitchen drain. Use the adjustable pliers to loosen the nuts to replace the washers. You will have to pull the fittings apart to get the new washers on.

Tighten the nuts back up, snug but not too tight. Try running some water and see if you have solved your leak. Did you? Good you are done with this bathtub drain repair.

Leaking Drains

A leak around the drain is another matter. The strainer is held in place by a large nut on the bottom of the tub. The flange of the strainer is sealed with plumbers putty. There is also a rubber gasket between the big nut and the tub. Whenever you disturb this connection you have to put new plumbers putty around the flange.

They make a wrench that can loosen the strainer but the average person does not have one. The handles of metal pliers will work to loosen it if you use a screwdriver for torque. Loosen the strainer and clean the old putty away. Check the rubber gasket, if it is worn or broken, you should replace it. Put a new bed of plumbers putty around the drain and thread the parts back together.

Use the pliers and screwdriver to tighten the nut. The putty will ooze out, this is normal. Get the strainer good and tight. Then clean up the excess putty. Try running some water down and see if you have completed this bathtub drain repair.

Troubleshooting Clogged Bathtub Drains

The first thing you need to do is determine if you actually have a clogged bathtub drain. When you run the sink or flush the toilet, does some or all of the water back up into the bathtub? Are the toilet or the sink running slowly? Does water from a fixture somewhere else in the house back up into the bathtub. A yes answer to any of these questions could mean one of the main sewer lines is clogged. This is where you may need some professional help. Efforts to clean the bathtub drain will be futile if the sewer is clogged.

Hair is the biggest culprit for clogging a bathtub drain, see the section below on how to remove it. It only takes a few minutes and a screw driver.

Removing Hair

Hair, especially long hair can have a tendency to clog a bathtub strainer. When my two daughters were still living at home, cleaning the hair out of the drain was a regular part of my life. The good news is that it is a quick easy job.

Use a screwdriver to remove the strainer. Pull it out and see if there is a ball of hair there. Use the screwdriver to dig it out. You probably don't want to keep it, so flush it down the toilet or throw it in the trash.

Some bathtubs have a strainer that closes with your toe to stop the drain. You use this when you want to fill the bathtub. Similar to the strainer, you want to remove it and check for hair. There are different kinds but it should have a screw of some sort that holds it together.

See if the drain works now by running decent amount of water down it. Does that water go down? Yes, Great you have successfully fixed a clogged bathtub drain. Yes, it really was that easy, just accept it.

Plunging a Bathtub Drain

Plunging a bathtub drain is not a recommended course of action. It is likely to fail.

I am not going to tell you not to try a plunger on a clogged bathtub drain. What I will say is that it has a poor chance of succeeding. The vertical tube for the overflow will diffuse the pressure too much to make the plunger effective.

You can try holding a rag over the overflow to block the opening. Unfortunately the air in the tube will compress much easier than the clog will dislodge. Try it if you want, I won't say 'I told you so'.

>

Block off the overflow and plunge several times and then try the drain to see if it helped. It probably didn't but it is possible. By this point you should have checked the stainer for hair, See Step One.

Summary

It is my hope that your clogged bathtub drain was easy to deal with. Removing a little hair, not hard at all. Did you need to repair the stopper assembly? Still not that hard. Or were you one of those unfortunate few that had to use a snake. OK, I admit it, not fun, dirty and a bit more work. Did you get through it? Are you a better person for it?

Now what do you do? As a homeowner you probably have a list of things to do. Don't feel like it right now? Take some time to enjoy the success of this project.
