How to unclog a bathtub drain with standing water using a plunger
If you can’t get any water down the drain because the bathtub is clogged so badly no water is getting through, it’s time to use some force.
Your next step will be to use a plunger to try to suck out and dislodge any clog in your bathtub. There are specific sink plungers you can use on sinks and bathtubs, which are smaller than a toilet plunger.
This is a good one because the size of the mouth will fit over most drains, and the accordion style of the plunger is better for unclogging sinks and for unclogging a shower drain.
- Fill the bathtub with water up to a few inches. You will need to do this so that the plunger can get proper suction on the drain.
- Plug the overflow hole. To do this, you may need to unscrew the overflow plate and set it aside. The overflow hole needs to be plugged or covered up with a towel to keep the air pressure tight.
- Use the plunger on the drain. Spend some time plunging the drain but beware that if something does get dislodged, it may come up and into the bathtub. Give it a few plunges (10-15 times) and see if anything comes out.
- If nothing is coming out of the bathtub, apply a little more force to see if anything can be dislodged.
- If you dislodge the block, the dirty water will begin to drain.
- Run some water down the drain to make sure it is flushing properly.
- Replace the overflow plate.
- If this doesn’t work, move on to the next method.
At this point, it’s looking like whatever is clogging your bathtub is in there pretty good, so we will need to use some more tools to see if we can get the blockage out.
How to unclog the drain using a drain claw or a plumber snake
If you have a stubborn clog in your drain, using a claw or a snake can help you. These items are fairly inexpensive, and you can buy them at any hardware store or on Amazon. The drain claw tends to work better as it is easier to use in this situation. However, it is always good to have a plumbing snake as a household tool. Here are the steps to unclog a drain using a drain claw.
- Removed the tub drain stopper and the strainer to get access to the pipes.
- Insert the drain claw as far down into the drain as possible. Remember that your drain pipes will bend, and there will be a drain trap in the curve. So you will need to push through the resistance.
- Keep pushing through the trap to ensure you get a thorough clean.
- Once you have successfully pushed the claw through the trap, you can start to extract the claw from the drain, and it will grab any blockages that may have happened with its hooks.
- Once you have removed the debris, make sure to clean the snake or the claw thoroughly; otherwise, it may not work for you next time.
- Test the drain by running water down it to see if the water is draining faster. If the water is draining smoothly, you are done.
- If the water is not draining any faster, keep reading.
How to unclog a bathtub drain using chemical cleaners
Since you have now tried a natural way and the physical way removed the block, the next step is to purchase a chemical cleaner to try and dissolve the blockage.
*Warning: When using chemicals, it’s important not to mix different types together as they could cause an unwanted chemical reaction. These chemicals can release toxic fumes into your house, so please make sure to follow the guidance of the manufacturer.
Step 1: Put on your protective gear.
You should be wearing protective goggles and gloves and even a mask. Inhaling these chemical cleaners can cause you to choke, speaking from experience. Since this is going to be causing a chemical reaction, it’s a good idea to keep the room properly ventilated by opening windows in the area to get airflow.
Step 2: Read the instructions of the product.
When purchasing a chemical product for your plumbing, it’s good to know what type of plumbing you have. Is it plastic piping, copper piping, or something else? Make sure that the chemical cleaner you were using is the right one for your types of pipes otherwise;, you could cause damage and have a bigger issue on your hands.
Step 3: Follow the Instructions
Assuming you’ve already removed any standing water (make sure to do that first!), follow the instructions on your chemical cleaner using the right amount of product in the drain. Do not assume that using more is better or by using less will give you more chances to do it. You want to make sure you are following the instructions of the manufacturer to a tee because you are working with harsh chemicals, and it’s important to get it right.
Step 4: Wait
Once you put the chemicals in the drain, it’s important to leave it for the amount of time suggested. You need to make sure you are giving enough time for the chemicals to do their job. Giving it less time than the manufacturer’s suggestion can prevent it from having the right effect.
Step 5: Flush the drain.
When the wait time is finished, you will want to run cold water down the drain (unless the product specifies otherwise in the instructions) and take note of how fast the water is draining out of the tub. If there has been no significant improvement in the water draining, there could be a bigger issue, and it’s time to move to the last step.
