How To Install Kitchen Sink Drain

Prepare for the New Kitchen Sink Before you begin this project, read the manufacturer’s instructions and follow all local building codes. If you’re not comfortable installing a kitchen sink or related components (faucets and garbage disposers), Lowe’s can do it for you. Select the appropriate type of replacement sink. Single- and double-bowl drop-in sinks can be installed into most countertop surfaces. Undermount sinks install beneath the counter and should only be used with solid-surface and natural or engineered stone countertops. These instructions are for installing a drop-in sink. Step 1 Measure your existing sink. If your new sink has different dimensions and drain location(s) than the unit it will replace, you may need to modify the countertop opening and / or plumbing. Good to KnowFor best results, make a drawing of your old sink with all measurements including distances from the sink wall to the drain center to use as a shopping aid and reference. Or you can remove your old sink, take it to Lowe’s, and ask a Lowe’s associate to help you select a replacement unit. CautionWear safety glasses when working under the sink or cutting pipe and other materials. Step 2 Decide if you will also replace the faucet or install additional components such as a sprayer, soap dispenser, on-demand hot water tap or filtered water tap.Standard sinks have 1, 2, 3 or 4 holes on the rear lip for a faucet and additional components.Installation of a new faucet and other components is easier if it is done when you are installing a new sink, since you can easily access the hardware with the sink out of the countertop.

Remove the Old Sink Before you begin, snap a picture of your plumbing configuration. This serves as a handy reference if you’re having trouble reassembling the plumbing later. Step 1 Turn off both the hot and cold water supply lines. The shutoff valves typically are in the cabinet below the sink or in the basement. If you cannot find them, turn off the main water line to the house. Step 2 Turn on the faucet to relieve water pressure in the lines. Step 3 Use adjustable wrenches to disconnect the water supply lines to the faucet. Have a small bucket ready to catch any water left in the supply lines and drainpipes as they are removed. Good to KnowLeave the faucet attached to the sink. You can remove both the sink and the faucet as one unit. Step 4 If you have a garbage disposer, turn off the circuit, then unplug it. Use pliers to disconnect the drainpipe and P-trap from the sink drain. Keep a bucket or pan underneath the drain to catch excess water. Step 5 Then remove the dishwasher drain line. Step 6 Remove the disposer following the manufacturer’s instructions. If you don’t have your disposer instructions, check the manufacturer’s website. Have a bucket ready to catch any water. Most disposers loosen at the mounting bracket connection to the sink drain and twist off. Step 7 Locate the metal clips under the counter around the sink’s perimeter. Loosen them with a screwdriver, open-end wrench or socket wrench and swing them toward the sink bowl. Step 8 Cut the caulk around the sink with a utility knife. Step 9 Push the unit from underneath and lift the old sink away. Step 10 Use a putty knife to remove grime, caulk and old plumber’s putty from the countertop. Likewise, clean any components you will re-install.

Replace a leaky sink basket Test for the leak Fill up the sink with water and touch a facial tissue between the bottom of the basket strainer and the sink. If the tissue picks up any water, you’ve got a leaky basket strainer. Loosen the coupling nut Loosen the coupling nut at the base of the strainer basket with a slip-joint pliers and slide the nut completely off the threads. If the basket spins, hold it tight as in Photo 3 Unscrew the locknut Use 16-in. slip-joint pliers or spud wrench to unscrew the strainer locknut. If the entire basket spins, insert the handles of a pliers into the strainer grate from above and stick a screwdriver between the handles to hold it still. Reach over the front of the sink, or have an assistant hold the screwdriver from above. If you can move the drainpipe out of the way, you can insert the pliers handles up into the strainer grate from the bottom to get a better handle on it yourself. Apply putty and reset the basket Roll plumber’s putty between your hands into a rope the size of a pencil and wrap it around the lip of the drain opening. Press the strainer firmly down into the putty, add the rubber gasket, friction ring and locknut under the sink, and retighten the locknut. If you discover a puddle of water in the cabinet under your sink, it may be caused by a leaky basket strainer. Old plumbing fittings can be tricky to loosen, but we’ll show you how to tear them apart and put them back together without any strain. You can pick up all the necessary supplies at a hardware store or home center. To be sure the leak is coming from the basket strainer instead of a pipe joint, test the basket for leaks as shown in Photo 1. Once you confirm that the basket strainer is leaking, begin the removal process (Photo 2). Photo 3 shows how to remove the strainer locknut, which holds the basket tight to the sink. If the locknut is rusted in place, spray it with penetrating oil. If you don’t have large enough pliers to get a good grip, loosen the locknut by tapping the locknut &Idquoears&rdquo with a hammer and an old chisel. (If the locknut won’t move, see the next step, below.) Completely remove the locknut, friction ring and gasket, and lift the old basket out of the sink. Scrape off the old putty with a plastic putty knife so you don’t scratch the sink. Seal the new basket in the sink with plumber’s putty as shown in Photo 4. Plumber’s putty cannot be used on certain new sinks, but these will be labeled to that effect. If you can’t use plumber’s putty, use a non-water-based silicone. Excess putty will squeeze out between the new basket strainer and the sink when you tighten the locknut in place. Wipe it off with a rag or paper towel. Make sure to insert the cardboard friction ring between the rubber gasket and the locknut so the locknut spins freely, without catching on the gasket. Back to Top Drastic measures for stuck nuts Cut the locknut If all else fails, chuck a metal cutoff wheel into a rotary tool and cut the locknut. Cut until you reach the cardboard ring above the nut. Don’t cut into the sink. If the nut still doesn’t spin, fit your chisel into the cut area and smack it with a hammer to crack it open. Wear eye protection. Buying Tips You have to spend at least $50 to get a high-quality kitchen sink basket strainer assembly with a durable finish and a reliable stopper mechanism. The best strainers have either a spin-lock or a twist-and-drop style stopper. The spin-lock stopper doesn’t have any parts that can wear, but screwing it in and out can be annoying. The twist-and-drop style is much easier to use but requires occasional O-ring replacement. Avoid push-in style strainers that have a nonreplaceable neoprene stopper or a plastic knob. The plastic parts break and can lose their sealing ability if exposed to boiling water. Strainer/drain assemblies Back to Top

How To Install Kitchen Sink Drain

Kitchen drain pipes may look complicated to install and tempt you to call a plumber. Don’t. In spite of appearances, the entire assembly is actually simple and easy to install, repair or replace. What may be referred to as the “drain pipes” is actually three key pieces, coupled together — the sink drain tailpiece, which runs from the sink down to the curving pipes; the curving portion of the drain pipes, called a trap due to the fact that it captures or rather contains sewer gasses; and the actual drain pipe itself, hidden inside the walls. As long as you have a few key tools, almost any homeowner can handle hooking the kitchen sink to the home’s drain system.

Step Two // How to Install a Kitchen Sink Lay out Sink Location Photo by Keller & Keller Mark the counter’s back edge to center the sink within its cabinet. If sink has a template, align it with the mark on the counter. Place its back edge 1½ inches from and parallel to the counter. Trace around it; proceed to the next step. If there’s no template, use 2-inch tape to outline the sink location. Mark the center of the sink on its back lip. Lay the sink upside down on the counter. Align the mark on the sink with the one on the counter. Adjust the sink to leave 1½ inches between its back edge and the backsplash. Be sure sink is parallel with the counter’s edge. Trace around the sink, then remove it. Measure the width of the sink lip, subtract 1/8 inch, and mark inside the sink outline by that much. To make the cut-out lines, connect all the marks with a straightedge.
