What to do when your sink is backed up!
Since the dawn of indoor plumbing, it’s well-accepted that water is to flow down the drain. When water does the opposite and flows back up through the drain, it’s a pretty good indicator that you have a problem. But where to start? If your sink is backed up, there are a number of contributing factors that could be causing the problem.
Something lodged in the p-trap
Hair caught in and around the drain stop
The buildup over time of soap, lotions or grease
Clear the Drain Stop When Your Sink is Backed Up
When a sink is backed up, there are a few things to check before calling a professional.
Check the area around your drain stop. The least invasive method to clear the drain is to check and see if the drain stop has hair or another foreign object clogging it.
When hair or other materials start to build up in the drain stop area, it can also start accumulating other debris, making the clog worse. Clearing the drain stop, and keeping it clear, is imperative when the sink is backing up. Once cleared, run some water into the sink.
If it is still backing up, then it is time to move under the sink.
Clearing the P-Trap
The next place to check when your sink is backed up is the p-trap. The p-trap is the name given to a plumbing device designed to prevent sewer gases from coming back up the drain. The bend in the pipe fills with water that forms a barrier keeping those noxious gases from re-entering your home.
The p-trap has a secondary purpose of trapping any items that may mistakenly fall down the drain. The device gets its name from its similar appearance to a sideways letter “P,” and you’ll find it directly below your sink’s drain.
When your sink is backed up, the p-trap is a good place to start. It’s easily accessible, and items or debris stuck in the p-trap are the most common cause of backed up water. No matter if the pipes under your sink are PVC or metal, the p-trap should be easy to remove by unscrewing the slip-nut joints on either end. Take care when removing the p-trap so as not to spill the water trapped in it.
Once you have it removed, check it for items lodged in it. Check it also for build-up that may be restricting the flow of water through the p-trap. Once you have it cleaned out, reconnect it and check to see if the water is flowing freely.
Buildup in the Pipes
If cleaning both the drain stop and the p-trap doesn’t resolve the problem when your sink is backed up, the problem may be deeper. It may be a
