Kitchen sink leaking, kinds and a solution to the problem

Water leaks from under the sink are usually easy to find and solve, but still, a leak can cause a lot of damage. Water that damages the body or floor may come from drainpipes, feed hoses, or even from the tap itself. To find the source of water leakage, you need to look under the sink with a flashlight and a dry cloth. If the leak is large – it is immediately visible, but because the place of joints of the gate or tap may slightly drip, try to lean a dry cloth if it is instantly wet, then there is a leak. Repairs in most cases are based simply on tightening the fastening, but there are cases that are more complex.

Assessing the scale of the problem

How to fix a kitchen sink leak

The first sign of a kitchen sink leak is often a water-soaked locker or water on the floor. If a leak occurs from the water supply hose, under pressure, the spray will be instantly noticeable. However, if a leak is coming down the drain line, you may not notice it until you use the sink. In addition, if the problem is a faulty seal around the drain sink, in order to notice a leak, you will need to fill the sink with water before the water flow is obvious. In most cases, a leak can be detected by a damp wall near the sink or by a puddle on the floor.


How to fix kitchen sink leaks from the water supply hose


water supply hose leak under the sink

If you notice active splashing of water under the kitchen sink or drops of water from the connection points of the water supply hose, then they are the problem. Since the water in the hoses is under pressure, if there is a leak, it is immediately noticeable. A common source of leakage is shut-off valves with compression fittings that are not tightly screwed. The best way to tighten them is to hold the valve with one spanner, and you turn the coupling nut with the other. There may also be leaks from the tap connections, which are difficult to tighten because they are located in an inconvenient place behind the sink. They are best tightened not with a wrench, but with adjustable or locking pliers.


How to fix a leak in the sink siphon

Looking for a leak in the siphon

It should be borne in mind that the correct installation largely depends on the serviceability and durability of such plumbing equipment as a siphon for a sink or sink.

Why is the siphon dripping? There may be several reasons for this:

  1. Low-quality installation. It may include loose joints, skewed threads, loosely tightened cap nuts, and unsuitable gaskets.
  2. Clog.
  3. Hardening and compression of rubber gaskets (unfortunately, this is inevitable over time).
  4. Cracks or chips.

The first thing that catches your eye is always a blockage. You turn on the tap, and the water, instead of going down the drain, comes back. If there is no blockage, simply inspect the siphon from all sides. This way you can see cracks or chips. If nothing like this is found, it remains only to disassemble the siphon. During the analysis, you will notice all the disadvantages of the installation, if there were any. If everything is in order here, the last thing to do is to check the gasket. It should fit the size, be soft and flexible, and not have cracks. If there is a blockage, it is enough to Unscrew the lower part of the siphon and clean the sewer with a cable or wire. Also, chemicals for cleaning pipes (you can buy in any store of household chemicals) also help quite well.

removing a blockage in the sink

The old gasket can be smeared with a thick layer of sealant or silicone gel and returned to its place. So it will serve for another couple of years. But it is still recommended to replace it with a new one, it will be more reliable and durable. When replacing, you can only cover the joints with sealant, and it is enough to apply liquid soap a greasy cream or to the gasket itself.

With cracks and chips, the same story. It is better to replace the entire siphon. If it is not possible to do this immediately, you can try to seal it, so the siphon may work for some time until you replace it.


If the faucet leaks?

If the faucet leaks

The situation when the faucet flows in the kitchen, in everyday life happens quite often, and it is not always convenient and profitable to call a repair master. Almost all failures in plumbing can be eliminated by yourself, if you correctly determine the reason why the faucet drips, leaks or is generally faulty. If there is a leak in the kitchen tap under the sink, the water supply hose may have leaked due to damage, or the gasket was worn where it was connected to the housing.

When the kitchen faucet flows at the junction of the spout with the housing, the leaky base has damaged gaskets or they are severely worn. To fix the problem, you should purchase new rubber gaskets and replace the old worn rubber rings with a new seal.

In this case, you can run to the store for a new hose or seals. Repair consists of replacing the entire hose or the rubber o-rings on its outlet pipe at the connection point. Spillage of the mixer can occur if its body is damaged, the main reason for this defect is clogging of the filter at its outlet, as a result of which the water pressure leads to cracks in the metal tube. If the fault is found in single-lever models with a built-in non-removable cast, you will have to completely change the mixer with the exception of the cartridge. In a design with two fans, the gander can be easily removed and replaced with a new one.


Sometimes the faucet starts to work poorly after a while for no particular reason, and it is not immediately clear what to do if the faucet drips. The main reason for this failure is the formation of lime salt deposits on plumbing parts.


In this case, you need to disassemble and clean the faucet, using special household chemicals to clean sanitary equipment from lime plaque.

Water leak in the sink itself

It is necessary to install the sink tightly and hermetically so that there are no leaks

If you have checked all possible leak options, and everything works fine there, then the problem is in the sink itself. If it is a sink leak, you need to Unscrew and remove the sink, and replace the plumbing putty, usually this will solve the problem.

These are some of the most common types of leaks. If you put a little effort, you will most likely easily determine the cause of the leak of the sink, and our advice and your clever hands will help to eliminate them.
