Leaks under sink can create a lot of damage. Most homeowners just simply call a handyman to fix it. Well, it needs budgets of course. Actually, you can fix this problem by your own hands. Some problems can be easily seen just when you open the cupboard and use a flashlight. Some problems also just need some tightened connections. However, you need to find the problem first then find the ways to fix it.
Assessing the Problem
You need to find the problem first. The first indication of the leak can be a water soaked floor or cabinet. If you see the leaks come from a pressurized water hose, then you will see spray. If the leaks are from a drain line, you cannot find the problem unless you use the sink. If you still cannot find the problem, you can try letting the water stand until you see the leak. Standing water or dampness can be the cause too.
Fixing Leaks in Water-Supply
The water in faucet supply will spray from defective pipes or loose connections when it is under pressure. Drips are commonly from shut-off valves that are not as tight as it should be. Tight the valves to fix this problem with one wrench. If the problems or the leaks are from faucet connection, then it will be more difficult to tight as it is located in the cramped spaces right behind the sink. You need locking or adjustable pliers to fix it.
Fixing Leaks in Drain
Leaks you see in a P-trap can be caused by loose connections or a blockage in drainpipes. In a metal trap, it can be corrosion. If you have tightened and you still trap leaks, then it is good to remove it then clean it. At the same time, use an auger to clear the drain if you think it is caused by a blockage. For plastic P-traps, you can tighten the compression nuts and for metal traps, you need pliers. If you see the metal trap nuts are quite hard to run, it can be corroded. It is the time to replace it with new trap.
Fixing Other Leaks
If you cannot find the leaks from those above, then you can suspect sink drain. It will only leak when you see the sink or faucet is full of water. Well, usually you can notice the faucet leaks from above the sink, but sometimes water will flow down of your faucet, then it drip underneath your sink. In this case, it will not be visible. To fix it, it depends on the faucet type you have. Sometimes, it needs disassembly as well as replacement of one or more washers or gaskets.
Well, if you have tried hard to find the source of the problem or the leak and you still cannot find it, may be it is the right time to call a professional. But, try to fix it by your own hands first since sometimes it just needs very easy and simple reparation that you can do in minutes.
