Conclusion
There are a few things you can do to help clear a slow drain. Pour a pot of boiling water down the drain to help loosen any build up. Use a plunger to help dislodge any blockage. You can also try a drain snake to help clear the drain.
If the drain is still slow, you may need to call a plumber to help clear the blockage.
