Before you change the pipes under the sink, you need to take some measurements. The height of the trap arm under the sink is a crucial factor to ensure that you get the right height. This is a long horizontal piece of pipework that slopes toward a wall outlet or branch drain. If it’s too high, you’ll have to move the drain outlet to accommodate the new pipe. If you have trouble doing this, don’t worry, you can easily fix the problem yourself with the help of a few simple tools.
Before you begin replacing the pipes under the sink, you must first check for leaks. The leak is usually coming from the joints. Old metal pipes can develop a pinhole leak at any point and in the trap. You can fix this problem by installing a new one for a reasonable price. Before you install new sink pipes, be sure to check the water supply lines to ensure that the connections are tight. Another issue that could cause leakage is loose coupling nuts, which connect the pipe sections.
After measuring the pipes, you can begin installing new P-traps. These P-traps are generally sold as a kit. It contains a trap bend, a trap arm, and a tailpiece extension. The bend connects to the drain pipe, while the arm swivels down to the sink’s bottom. You can purchase the parts separately from hardware stores. If you’re not sure about the proper parts, you can always ask a plumber for assistance.
Secondly, you can remove the old sink drain. You can do this by unscrewing the locknut that holds the drain pipe in place. Another way to do this is to have a third person help you by placing pliers into the holes of the sink’s flange. Make sure the opening of the pivot rod is facing the back of the sink. Then, tighten the locking nut using channel lock pliers.
After you remove the old drainpipe, you can replace it with a new one. This task requires the use of pliers and plumber’s putty. Carefully turn the fittings in the pipe to ensure a secure fit. Once you have finished, insert the new one into the sink. Be sure to cover the sink with plastic wrap before you screw it into place. If there are any holes, you’ll need to put plumber’s putty around them to create a watertight seal.
If the drainpipe is clogged, you may need to replace the p-trap. Usually, a p-trap catches small amounts of water and prevents sewer gases from rising into the sink’s wastewater line. Some sinks have a valve on the bottom of the p-trap. If the p-trap is stuck, it’s time to contact a plumber to fix the problem.
