How to Fix a Leaking Kitchen Faucet
Step 1 Turn Off the Water
You want to turn off the water to the house, that way it's not flowing while you're making repairs as flowing water makes it nearly impossible to do repairs of this kind.
Step 2 Identify Your Leaks
To identify your leaks you're going to want to look at both the faucet itself, and beneath it. Sometimes leaky faucets are caused by cracks in the faucet itself that rests on the sink. Luckily this is an easy fix.
Step 3 Fix an Outer Leak
An outer leak is a leak that comes from the actual faucet piece itself, this is a remarkably simple repair to make. Just take your caulking and paste over the cracked areas. When this dries it will keep your faucet from leaking any further.
Step 4 Identify Inner Leaks
An inner leak is a leak that comes from problems with the piping. This is going to require you to get your flashlight and get underneath the sink. Turn on your flashlight and look for the leaks. If your leak wasn't caused by the actual faucet itself then this is where you're going to find it. There are two kinds of inner leaks. The first kind is the kind that's caused by piping simply not being tight enough and the second is the leak that's from holes in the actual pipe.
Step 5 Tighten the Fittings
If your leak was caused by loose fittings then you're going to want to use your crescent wrench in order to tighten them. Close your crescent wrench down on the area and move it in a clockwise motion. This will tighten your fittings; if your leak was caused by loose fittings, this is what's going to stop it.
Step 6 Use Your Fix a Flat
If your leak was caused by an actual hole in the piping then you're going to want to use your fix a flat tire seal. Fix a flat tire seal is used to seal holes in both bike and car tires and can be used to seal holes in water piping in much the same way, just be sure not to turn your water back on until it's one hundred percent dried, or else you'll get the tire seal in the rest of your pipes and it could contaminate your water.
