Why Is There Water Leaking Under My Sink? A Citrus Heights Homeowner’s Guide

One common cause of water under the sink is a loose or damaged drain connection. The drain assembly includes the sink drain, P-trap, slip nuts, washers, and connected piping. Over time, these parts can loosen, shift, corrode, or wear out. When water drains from the sink, it can leak through weak connections and collect inside the cabinet.

Another possible cause is a leaking P-trap. The P-trap is the curved section of pipe beneath the sink. It holds water to prevent sewer gases from entering your home, but it can also develop leaks at the connection points. If the trap is cracked, misaligned, or improperly tightened, water can drip every time the sink is used.

Water supply lines are another common source of under-sink leaks. These lines bring hot and cold water to the faucet. If a supply line is loose, cracked, corroded, or damaged, it may leak constantly or only when the faucet is turned on. Supply line leaks can be especially concerning because they may continue leaking even when the sink is not being used.

The faucet itself may also be the source of the problem. Water can leak from the base of the faucet and drip down through the sink opening into the cabinet below. This type of leak is sometimes mistaken for a drain leak. If the cabinet only gets wet when the faucet is running or when water splashes around the base, the faucet may need attention.

For kitchen sinks, garbage disposal leaks can also occur. A disposal can leak from the mounting ring, drain connection, dishwasher hose, or bottom of the unit. If the disposal is leaking from the bottom, it may be failing internally and could need replacement. The Plumbing Pros can help with faucet and fixture repair as well as sink, disposal, and supply line issues.

Homeowners should not ignore moisture under the sink. Dark cabinet interiors can hide leaks for weeks or months. Over time, moisture can lead to warped cabinet materials, mold growth, unpleasant smells, and damage to nearby flooring. A small drip can become a much bigger repair if it is not addressed early.

If you find water under the sink, remove stored items from the cabinet and dry the area as much as possible. Then run the faucet and watch carefully to see where the water appears. Check the supply lines, drain pipe, P-trap, faucet base, garbage disposal, and dishwasher connection if applicable. If water is actively leaking from a supply line, shut off the valve under the sink.

Citrus Heights homes may have older plumbing connections, especially in kitchens and bathrooms that have not been updated in years. Older shutoff valves, supply lines, and drain fittings can become brittle or corroded. Attempting to force old parts loose can sometimes create a larger leak, so professional repair is often the safer choice.
