Use Baking Soda and White Vinegar

Oftentimes you can fish out the clog or force it down the drain and into the PVC pipes.

Check your work with some water after clearing the drains to ensure the clog has been removed.

Ways to Prevent Clogged Kitchen Sinks

A little routine maintenance can go a long way to prevent any standing water in your kitchen caused by clogs. Do these things on a regular basis to save time and money.

Clean Your Garbage Disposal

Although it’s not a pleasant task, cleaning your garbage disposal out several times a year can help prevent clogs. Remember to use a pair of gloves, no one wants to put a hand in gunk and debris.

Depending on your setup, your garbage disposal might be located on the side of the sink.

Tip:

  • Don’t forget to clean the bottom of the unit.

Use Boiling Water

Using water to unclog a drain might not seem practical, but it can be quite beneficial to pour boiling water down your drain pipes occasionally. Doing this several times a year can help clear the drain lines.

You don’t need to fill the sink, but at least use a few gallons. It’s as easy as 1 2 3.

Clean out Your P-Trap

The p-trap, not a shortened version of Parent Trap, is the u-shaped pipe that is designed to hold a little water and prevent gases from the sewer and the likes from traveling up the drain pipe.

Another function of the p-trap is to help prevent clogs, so it’s important that it’s in proper working order.

Water should only be flowing in one direction when it comes to your drain pipe. You don’t want the path of least resistance to be back up the kitchen drain.

Tip:

  • A bad smell around the sink can be an indicator that you need to service your p-trap.
