<human>:  How do I fix a clogged drain?
<bot>: To fix a clogged drain, start by using a plunger or a pair of pliers to remove any debris that may be causing the clog. If that doesn’t work, use a drain cleaner or a drain snake to break up the blockage. Finally, if these remedies don’t work, it may be necessary to call a professional plumber to come in and use a hydro-jetting system to clear the drain.
