Why is my Kitchen Sink Clogged on Both Sides? 

Double sinks in your kitchen are super handy, one to wash and one to rinse the dishes or prepare food.  Problems start when your sinks starts to drain water slowly.  It might be one sink at first and then both.   

Dealing with the problem right away will prevent larger problems like clogs, overflowing sinks, and even floods!  If you don’t have a drain auger, we will go over a few ways to unclogs your sink with things you have around the house. 

Why are Both Sides of My Sinks Clogged? 

Each of your sinks has its own drain and pipe located underneath.  Those 2 pipes however, join into one larger pipe before they go into the wall.  That means that all of the junk that goes down your drain can collect where the two pipes join together. 

That junction will collect gunk, food, debris, and anything else that gets washed down your 2 sink drains.  If the kitchen sink main drain pipe clogs up, you will then have a problem with both sinks, not just one. 

Double Bathroom Sink Clogged on Both Sides 

Are your bathroom sinks not draining but the pipes are clear? See above, both sinks drain into the same pipe underneath your bathroom counter and this can cause clogs in the main pipe and at the joint where the 2 pipes come together into one pipe.  The solution for unclogging is the same when you have a double kitchen sink clogged on both sides.

Kitchen Sink Main Drain Clogged 

If you’re main kitchen sink drain is clogged, that won’t be a problem.  Below are a few solutions you can try to quickly and easily get your drains running clear again. So, how do you unclog a double sink with standing water?

Double Sinks Clogged at the P Trap

If you’ve got a double sink that is not draining and there doesn’t seem to be a clog…new flash…there probably is a clog, but it could be in the P Trap. Your Kitchen sink could be clogged at or past this u bend in the pipes.

What is a P Trap?

P Trap Under My Bathroom Sink

A P trap is the big main elbow in your drains that you can see when you open up the kitchen or bathroom cupboards under your sink.  The P trap is built that way so that is hold water in it.  

P traps are a building code requirement.  The water in the P trap blocks any gases from coming up from the main drains and getting inside your house.  

Once you see how big of a corner the P trap is, you’ll understand how gunk and debris can gather there.  Do yourself a favor and place a drain catcher in your sink to catch any weird stuff.  This way it won’t find its way into your drains and P trap.

Also, don’t put any food or grease down your drains.

Easy Fix: How To Unclog a Kitchen Sink Clogged on Both Sides 

What to do if both sides of your kitchen sink are clogged? How do you fix a double clogged sink? We have 4 quick and easy methods to unclog your kitchen sink drain.  Be aware that clogs happen not just because something random is in your pipes.  Clogs happen also because of built up gunk and grease  

  1. Plunger 
  2. Hot Water 
  3. Talon Drain Cleaner
  4. Drain Auger 

How do You Unclog Both Sides of a Kitchen Sink


Using a plunger on the drain should be enough pressure to get your drain flowing again.  Plunging the sink drain will dislodge any small things stuck in your pipes.  For sinks, you use what’s called a standard plunger, which is totally flat on the bottom.

Don’t use your toilet plunger, it’s got a special flap on the end that will stop you from getting a seal on your sink drains. Helpful in the short term but this is not a long term solution.  There is probably gunk built up in your pipes that needs to be removed.  Only a drain auger can do this. 

How do You Plunger a Double Kitchen Sink

Place your plunger right overtop of the drain on either side of the sink until it forms a seal over the drain. Then you use elbow grease to push the plunger up and down creating suction that should dislodge the clog. Run hot water down your sink to wash the clog away and confirm its gone.

Hot Water 

You can use very hot water to melt away some of the gunk and grease that has built up inside your pipes.  I recommend you plunge the pipes first THEN use hot water to attack the build up.  A drain auger is really the only thing that will solve your problem with build up long term. 

Talon Drain Cleaner – Professional Grade 

Like a rocket ship blasting through your pipes, Talon Drain Opener is what the Pros use. Because it’s Pro Grade it does cost more than your standard liquid drain opener.  BUT, you’re getting some kick butt results for the price.  It’s worth it.

We had a slow running sink drain, clogged up with hair and decided to test it out.  It’s not liquid like other chemical drain openers.  Talon is grainy, flakey and powdery and you put it into your drain and wash it down with water.

Our test showed that our drain ran like new after using Talon Drain Opener.  It’s also safe for septic systems and won’t wreck your chrome, plastic or brass sink fittings.

Exactly what you’d expect from a professional grade product like this.

You can grab Talon Drain Opener in either 1 pound or 2 lb containers. The bottle pictured here is the 2 pound container, which we always have on hand.  And the 2lb container is a great deal, costing only about 10$ more than the 1 pound container.


Drain Auger 

The best drain augers are built with sturdy rust resistant metal cords with a bulb on the end.  When you put an auger down your pipes, the bulb and cord work together as you twist the handle, hitting the sides of the pipes.  This removes years of built up gunk like grease, food, and hair.   

Drain augers are super affordable and easy to use.  You don’t need to hire a plumber to get this done yourself.  

Pro Tip
Don’t ever use drain cleaner in your toilet! Why? Because most drain cleaners produce a chemical reaction. That reaction creates heat.

Heat makes your pipes expand. Porcelain doesn’t expand or contract based on temperature so using drain cleaners will CRACK your toilet. Take our word for it, you don’t want to get THAT bill.

How to Prevent a Kitchen Sink from being Clogged on Both Sides 

There are a few things we recommend to stop your sinks from getting clogged.   

  1. Drain traps 
  2. Put grease and food in the garbage 
  3. Regular Drain Cleaning with a Drain Auger 
  4. Properly Using your garbage disposal

Drain Traps 

A drain trap is a super cheap and easy way to prevent anything from getting down your kitchen sink drain.  You can buy them for a few bucks online.  Place a drain trap in each of your drains to catch anything before it gets into your drains.  Then, just dump the stuff you collected in the drain trap into the garbage. 

Put Grease and Food in the Garbage 

If you cook anything that makes fat or grease, do not dump it down your drains.  This includes bacon fat, butter, oils, anything!  Instead use an old can or bottle and dump the grease inside that. 

Once its full, you can throw the can away.  This prevents build up inside your kitchen sink drains and in your pipes, especially where pipes join together. 

Maintenance with a Drain Auger 

Using a drain auger every 6 months or so, can help to keep your pipes and drain running clear.  A drain auger will remove all the gunk that builds up in your drains, pipes, and at the pipe joints/elbows, preventing any future clogs.  This is our recommended way to prevent clogs in all the pipes in your home. 

Preventing Clogs in Your Garbage Disposal

Homes with garbage disposals have more issues with their pipes and clogging. As soon as I moved into my new house, I removed mine because of this.

Make sure you run the disposal regularly, run it for longer than you think you should, cut food into small pieces before dropping it down the disposal. Frankly, we advise you to just use your garbage can and ditch the unit all together.

Home Remedies for Clogged Kitchen pipes: Fake News?

Home remedies always add hot water (nearly boiling) to their recipes. Everything from adding bleach, baking soda, salt, pop, vinegar, etc. Don’t buy into the hype.

What’s actually moving your clog is the hot water, as you pour it into your pipes it dissolves your clog just enough to allow water to pass through. Don’t be fooled though, the actual reason for your clog is still there and will, in the long term, cause more clogs.

What is a Drain Auger?  

A drain auger is a long flexible piece of steel cable with a bulb, spring, or pear shaped head attached on the end.  It’s attached to a handle or coiled up inside a canister.   

You can either manually hand crank the metal cable in your pipe, use a battery powered auger or a cordless drill.
