Most clogs that form in the “trap” (the second, U-shaped, horizontal section) are caused by foreign objects that clog the drain pipe. In this case, eventually the object will have to be physically removed. Here’s how to clean a trap yourself to clear the clog, and remove that toy car (or clump of hair, or whatever!) without calling in a professional!

First, before you start unscrewing the pipe, be sure that there is not residual drain product left in the pipe. If you used a drain product, flush with at least three gallons of water, but still be very careful with handling the pipe since there could be residual pipe cleaner. (If you experience a total blockage with drain product in the pipe, you should call a plumber.)

Next, put on rubber gloves. Then place a bucket underneath the pipe to collect water. Now you’re ready to unscrew the slip nuts on each side of the trap (or simply remove the clean-out plug if you have one). Let water drain into the bucket as shown.

Sometimes a toilet can unclog itself without the need for intervention. If it looks like the toilet water is draining, then there’s a good chance that the clog will dissolve on its own after 30 minutes or so. If there’s no improvement, try the methods above and wait for them to take effect.

However, if you’ve exhausted all your options and there’s no sign of the blockage budging, it might be time to call a plumber and obtain some professional advice.
