Identify the source of the leak

wake forest nc plumberIdentifying the source of a kitchen sink leak can be tricky, as it is often located beneath the kitchen counter and out of sight. Nevertheless, it is an essential step in fixing the issue. To start the process, first inspect any visible connections between the kitchen sink and its pipes; check for cracks, loose bolts or other evidence that something isn’t quite right. There may be gaps in the kitchen sink’s sealant too, which must also be inspected since they can be an indication of a bigger problem. The most common point of connection is a faucet-mounted supply valve — if you find water pooling around this valve, it’s likely that you need to replace the gasket or you may need professional service to diagnose further damage.

If you cannot spot any obvious signs of wear and tear or damage from around the kitchen sink itself, it is likely to stem from further along within the internal piping system. You should then seek professional help from a plumber to assess and repair any issues with kitchen pipes.

Why would a sink drain pipe leak at the connection?

Although kitchen sink leaks can occur due to many reasons, faulty connections are one of the major culprits. A kitchen sink’s drain pipe can leak at the connection due to a multitude of issues. In most cases, the source of a kitchen sink drain pipe leak begins with an improperly sealed connection between two pipes. Depending on the supply lines that have been connected, one of them could have a faulty O-ring or nut and washer assembly, causing a water leak only when the faucet is turned on. Additionally, if the sink has recently been installed, improper caulking during the installation process can now be allowing water out at the connection. Many kitchen sinks are made of materials such as stainless steel, steel and copper alloys; further corrosion and rusting might be playing a factor as well in underlying causes for leakage at the connection point.

Fixing a leaking drain pipe connection

Repairing a kitchen sink drain pipe connection can be a daunting task, but with the right approach and materials you can easily get the job done. Before starting the repair, it is important to identify what is causing the leak.  Is the connection too loose?  Is there debris blocking the connection?  Has a washer worn out and needs to be replaced? Sometimes, you just need to tighten the connection further if it has come loose.

Once you locate the point of leakage, start by cutting off power to any electrical fixtures near the kitchen sink, so nothing will happen if water gets on them. Next, unscrew and remove any old clamps or fasteners holding the broken pieces together. Finally, once all old parts are removed from their original locations, replace them with new ones that match up properly with other components before reattaching each component in place where they belong.  If there is debris blocking the connection, make sure you clear that out.  When you’re finished, secure the bolts and screws until they fit snugly.

Once this is all completed and nothing around the sink area is wet, you may restore power to the area.
