Repairing a Sink Water Supply Line Leak in 5 Easy Steps
Leaks under the sink may wreak havoc on your cabinet and flooring. The majority of under-sink leaks, on the other hand, are simple to find and repair. The water could be coming from the faucet, the supply hoses, or the drainpipes. You can save a lot of money by doing the repair yourself instead of hiring a plumber. We’ll provide you with a step-by-step instruction to repairing a leaky water supply line to your sink here.
Materials and Tools Needed:
- adjustable crescent wrench
- a hose for the water supply
- Teflon tape used by plumbers
- an empty bucket
Step 1: Figure out where the leak is coming from.
Since most sinks have both hot and cold water supply lines, turn on one faucet at a time to figure out which one is leaking. You can capture any water that spills out throughout the assessment in an empty bucket.
Step 2: Disconnect the dripping water supply line.
The faulty water supply line hose can be discarded by using a crescent wrench to turn the compression nuts on the line counterclockwise. The compression nuts on the water faucet’s base and the water supply valve must be removed as well. Before disconnecting the problematic water supply line, turn off the water supply.
Step 3: Replace the Teflon tape used by the plumber on the stem connection fittings.
Wrap the Teflon tape over the ends of the connection fittings on the water supply valve and underneath the faucet three or four times. Ensure that the tape is covering the threads on the connecting fittings.
Step 4 – Install the new line hose
After wrapping Teflon tape around the threaded ends of the connection fittings, install the replacement water supply line hose. To avoid damaging the connection fittings, exercise caution when tightening the compression nuts on the water supply valve and the base of the faucet.
Step 5 – Test the new installation
Turn on the water at the water supply valve once the installation is complete to test the new water supply line and look for leaks. If you’re happy with the repair, use a towel or rag to dry any water on the lines or other fixtures.
A leaking tap can waste up to 2,000 litres of water each month, according to Clean Up Australia Ltd., a non-profit environmental conservation organization. As a result, you should halt leaks as quickly as possible.
