How to Replace a J-Bend at a Bath Sink

The J-bend under the sink is also known as the P-trap, the U-bend and at times even only the drain trap. When there are a number of subtle differences between each of those fittings, they essentially mean the specific same pipe in a drain pipe system. Typically you’ll need no tools to get this repair since the joining nuts have been made to function as hand-tightened. In some cases, however, hand-tightening may not seat the drier correctly, particularly if your drain pipes are metallic, so slip-joint pliers may often be convenient.

Place a bucket under the J-bend pipe. Unscrew the compression nuts together with your hand, or if they don’t come loose, use a slip-joint pliers, turning them counterclockwise. As this is a drain trap, water is likely to be found inside the pipe. When the nuts are loosened, tip the J-bend upside down and drain the water into the bucket.

Inspect the compression washers as well as also the compression nuts. Generally, the compression nuts will be sound and are reusable. The compression washers can at times be reused; nevertheless, if there aren’t any cracks, pits or tears in the compression washers, they can’t be reused and must be replaced. Metal pipes will be fitted with rubber washers. These must also be examined and replaced if needed.

Acquire the exact copy of this J-bend you’ve eliminated. This is vital because the pipes under the sink were plumbed to match that specific size and style of J-bend. If any other sort of J-bend is employed as a replacement, you’ll have ill-fitting drain pipes that will be prone to leak. J-bends are available at hardware stores or garden and home or pipes shops. Generally, they are sometimes discovered in kits that have a new pair of washers and compression nuts.

Remove the J-bend in the bundle and dry-fit the pipe. It has to match up exactly. Then set the washers into the beveled edges of this J-bend and attach them in to place together with the compression nuts. Turn the nuts hand-tight, then check to see whether they leak from running water in the tap down the drain. If there is a slight leak, tighten the compression nuts 1/4-turn with slip-joint pliers. For alloy connecting nuts, dab plumber’s pipe dope onto the threads before tightening them down.
