3 Common Kitchen Flooding Issues Caused By Appliances

A kitchen flood is an all-too-common occurrence, largely because there’s more than one potential cause. Kitchens typically incorporate multiple fixtures and appliances that connect to water supply lines under municipal water pressure. Note that kitchen flooding doesn’t necessarily stay in the kitchen: In one recent report, an overnight kitchen flood spread water damage throughout two-thirds of an entire residence. Keep up with the status of kitchen plumbing and appliances to reduce likelihood of these incidents. Here are three common causes of a kitchen flood:

Refrigerator Ice Maker

Most kitchen floods are caused by a broken refrigerator ice maker water supply line or connection.

  • Be careful when moving the refrigerator. The supply line may become kinked or break if the refrigerator is shoved too close to the wall. Conversely, if the refrigerator is pulled too far from the wall when cleaning behind it, the water line or connection could be over-stressed and may rupture.
  • The typical OEM plastic water supply line degrades and cracks. It’s a good idea to replace the inexpensive plastic with a copper or stainless steel line that offers better durability.

Dishwasher

A dishwasher water line may slowly and silently degrade, leaking into the enclosed space underneath the appliance, then rupture entirely. Twice a year, remove the kick plate at the front of the dishwasher and inspect the space with a flashlight. Consider leaks or unexplained wetness a warning sign. Shut off the dishwasher water supply valve under the kitchen sink and call a plumber.

Under-Sink Systems

The cabinet beneath the kitchen sink may include water quality accessories such as canister filters or a reverse-osmosis filtration unit. A canister filter can leak around the seal or the canister itself may fail entirely, releasing water under pressure. A cracked plastic supply line from the sink cold water line to the reverse-osmosis filter unit and holding tank could also pose a risk of flooding. Inspect the system twice a year for signs of leakage or degradation of the plastic supply lines.
