A Plumber Repairs a Leaking Kitchen Sink.

Why is my kitchen sink leaking underneath?

A leak underneath the kitchen sink is a common plumbing problem, although it might go unnoticed for some time. Several possibilities exist that might be causing the leak. When a plumber provides kitchen sink repair, they’re going to check several possible issues that include:

  • A loose or damaged water line or water supply valve. Even when the faucet is turned off, water can still leak under the sink if this is the problem.
  • If a water line leak for the hand sprayer is far enough down the line, water might drip under the sink.
  • Corroded brass, copper, or galvanized steel drain pipes may cause a leak or connections that could come loose and create a leak under the sink.
  • A clogged P-trap, the clog could cause water to build up to drains and create a leak.

How do I fix a leaky kitchen sink drain?

Whether you have older pipes or a loose connection, a common reason for leaks under the sink is a leak in the drain. For this type of kitchen sink repair, try these solutions:

  • Check the drain basket for clogs.
  • Use a wrench to detach the drain pipe from the drain basket and check for cracks on the seals and pipe as well as damage to the washer. You’ll need to replace the pipe and washer if damaged. If there is no damage, check the parts under the sink basket.
  • Use pliers to remove the sink basket, and remove the drain basket.
  • Use a caulk gun to apply sealants under the drain basket and top of the water basin. Allow the sealants to dry. 
  • Reassemble the parts and make sure the screws and washers on the connections are tightened.
  • Let the sealants dry for two to three days to make certain all the connections are secured.

Kitchen sink repair kit

There are several kitchen sink repair kits on the market today, although some of the main tools and materials you’ll need are a wrench, pliers, a caulk gun, and sealant to repair cracks and keep parts held together securely. You can also find kitchen sink installation kits that will have all the parts necessary to install a new sink. As with any plumbing repair, if you are uncertain about the best way to make the repair, get in touch with a professional. You don’t want to cause any serious damage to your plumbing that could lead to even more costly repairs. 

Kitchen sink crack repair

If you have a ceramic or porcelain kitchen sink, cracks may develop in the basin. Those cracks need to be repaired as soon as possible to prevent other serious problems from occurring. Fortunately, cracks are fairly easy to repair. 

  • Clean the sink thoroughly, removing all dirt and grime using an all-purpose cleaner and sponge. Allow the sink to dry.
  • Sand the chipped area lightly using 400-grit to 600-grit sandpaper. Roughen the chip’s edges slightly so the paint will adhere better.
  • Apply porcelain filler to the chip in layers until it is completely filled in. Allow each application to dry and lightly sand it before applying the next layer.
  • After allowing the filler to dry, apply porcelain touch-up paint. Follow manufacturer instructions when applying the paint.

Kitchen sink disposal repair

When it comes to kitchen sink repair, outside of leaks and repairing faucets, garbage disposals often pose problems, especially if they are clogged. Whenever you’re checking your disposal, never stick your hands or fingers inside it. Although the blades aren’t razor-sharp and are unlikely to slice your fingers, they can still bruise and otherwise harm your hands. 

Sometimes a disposal repair is a pretty simple fix. If you flip the switch and the motor doesn’t begin humming, this usually means there is an electrical problem. Make sure the disposal is plugged in, first. You can also try resetting the unit. The reset button at the bottom might have tripped a circuit. If it’s sticking out slightly, this is probably the case, and you can push it in to reset it. Other electrical problems should be handled by a professional. 

If you turn the disposal on and it hums but does nothing else, the flywheel inside is probably jammed. Often the clog is caused by something large like a bone or utensil. If you can see the cause of the clog using a flashlight, you may be able to remove it with pliers. Leaks and similar problems are best left to professionals.

How do I replace the plumbing under my kitchen sink?

Replacing the drain pipes under your kitchen sink is actually fairly simple, especially the curved pipes, or P-traps. To make this kitchen sink repair, before removing the old plumbing, you’ll want to put a bucket under the P-traps and shut off the water valves.  

  • Measure the pipes with a tape measure so you can get the right-sized replacements.
  • Unscrew the P-trap connections from the sink tailpiece, twisting the nut counterclockwise with your hand or a pair of adjustable pliers.
  • Once loosened, you can pull them from the connections and turn them upside down to drain them in the bucket if any water remains in them.
  • Traps connected to a common tee are removed, along with the tee.
  • Begin installing the new pipes (PVC preferably to avoid corrosion) by screwing in the new tailpieces.
  • New pipes are cut with a hacksaw to match the old ones you are replacing. The pipes should be the same diameter.
  • Use compression fitting to assemble the pipe and tighten the nuts by hand, until ready to install the P-traps. 
  • Each trap is slid onto the tailpiece and the nut tightened. The trap is swiveled to meet the pipe going to the drain. Assemble that end and tighten the nut.
  • Finally, fill the sink, and then open the drain to check for leaks. Tighten leaks with pliers.

When should you call a plumber for a clogged drain?

While some clogs might be easy to clear, other clogs are serious business and best left to a plumber to clear. If you have a clog that’s created a big mess, and the mess is spreading, it’s usually best to call a plumber. Clogs that affect every drain in the house should be cleared by a plumber. If clogs are affecting major drains like the kitchen sink, you should probably let a plumber take a look at it.
