A busted or leaky kitchen sink drain pipe can be a pain. Because all the water that comes into the kitchen sink has to go out through the drain pipe, a leaking pipe will continuously drip water in the cabinet below. This can cause wood damage or make the floors slippery, creating a hazard. Luckily, there are a few methods you can use to repair a kitchen sink drain pipe.
- Skill level:
Things you need
- Repair tape
- Repair glue
- Silicone caulk
- Caulk gun
Clear out the area underneath the kitchen sink. This will give you more room to work and also allow you to more easily pinpoint the problem.
Locate the kitchen sink drain pipe you need to repair. Look for cracks or leaking water to help you find the exact spot that needs fixing. It may help to turn the water on so you can more easily see a leak. Use the flashlight to illuminate any hard-to-see spots in the plumbing.
Dry off the area around the leak with the towel. This will help your repair adhere better.
Wrap the area with plumbing repair tape. There are different products available on the market. This tape is wrapped around the leak, and then a special adhesive is applied to the tape. The tape then cures and seals the leak tightly. This method is good for use on hot water pipes.
Apply plumbing glue. As with the repair tape, there are a number of solutions out there. The glue is applied over the leak and, after drying, seals the leak tight.
Seal the leak with silicone caulk. Insert a tube of silicone caulk into your caulk gun. Trim off the end at a 45-degree angle at the 1/8-inch mark. Apply the caulk directly over the leaking area. Allow it to cure, then apply a second coat. This is useful for quick emergency repairs when you have nothing else on hand.
