Shut Off Water Supply Before Repairs
Before doing any work under your sink, it's crucial to shut off the water supply. Start by locating the main shutoff valve for the house and turning it off. This will prevent water from entering the pipes.
There are also hot and cold supply line shutoff valves located under the sink. Turn these valves clockwise to shut off water to the faucet. Test to make sure the water is fully off.
Removing Drain Pipes and P-Traps
The p-trap is the curved pipe that connects the sink drain to the wall outlet. P-traps hold water, which prevents sewer gases from entering the home.
To remove the p-trap, use a wrench to loosen the slip nuts on each end where it connects. Place a bucket underneath to catch any water. Inspect the trap and remove built up gunk and debris.
The trap can then be replaced if cracked or corroded. Reattach using the slip nuts, making sure to keep it secured in place.
Unclogging Slow Drains
If your kitchen sink is draining slowly, there are several DIY methods to try before calling a plumber.
First, use a zip-it style plumbing snake to remove hair and debris that may be clogging the drain. Or apply a chemical drain cleaner and let it sit to dissolve buildup.
Taking apart the p-trap may reveal a stuck clog that can be removed manually with tongs or a coat hanger.
Fixing Leaky Pipes and Connections
Leaks under the kitchen sink often come from loose slip nuts on the pipes or worn out gaskets and washers.
Check for drips and tighten any slip nuts that may have vibrated loose using pipe wrenches. Replace any corroded piping with new copper or plastic pipes.
If the leak is coming from the faucet itself, you may need to reseat washers in the faucet valve or replace the cartridge.
Installing New Faucet Supply Lines
When installing new supply lines, apply teflon tape to prevent leaks. Connect the lines to the shutoff valves and faucet using wrenches to tighten.
Slowly turn the water supply back on and check for any drips or leaks at connections. Tighten further if needed.
To keep your under sink plumbing in good shape, remember to periodically clean out the p-trap and drain pipes. Inspect for any leaks or damage regularly as well.
Using sink strainers can also help catch food and debris before it goes down the drain.
With the right tools and know-how, most under sink plumbing repairs can be DIY jobs. Follow these tips and enjoy the satisfaction and cost savings of doing your own home plumbing work.
