The 6 Areas of Your Home Most Likely to Have a Water Leak

Tuesday, January 8th, 2019

water leakWater on the move inside a structure often seeps far from where the leak actually occurred. While no room is therefore totally immune to water damage, some spaces are definitely more leak-prone than others. Here are six locations most likely to be the point of origin for leakage.

Roof leakage into the attic often goes unnoticed. By the time it’s obvious, mold growth is established and wooden attic structure as well as insulation may be permanently damaged. Inspect the attic regularly and don’t ignore signs such as dark spots appearing on ceilings in rooms below.

All water supply lines eventually lead to bathrooms. Leakage may appear as dripping or seepage at under-sink or toilet valve connections. Leaky shower stalls gradually rot the subfloor beneath and penetrate ceilings below. A clogged, overflowing toilet is a costly damage clean-up—make sure flushing is complete before leaving the bathroom.

Chronic leaks under the sink and disposal cause ongoing damage and may precede a more major failure that includes severe water inundation. Remove the dishwasher kick plate, too, and look underneath for chronic leakage from the pump or connections that may rot the floor. Check the icemaker water line connection on the rear of the refrigerator.

Laundry Room
If the washer utilizes rubber hot/cold water supply hoses, be aware that these can rupture without warning and flood the house. Replace with braided stainless steel lines, ASAP. Always monitor the unit in operation—never leave the house or go to sleep while the washer is running.

Utility Room
Typical water heater lifespan is less than 10 years. Leakage is usually the first sign of a failing unit and, potentially, an impending tank rupture that could cause severe water damage. Call a plumber immediately if you note leakage or pooling around the unit.

Many water supply lines are routed through the basement. Dripping pinhole leaks and/or more subtle signs like mineral residue on pipes caused by seepage isn’t “normal.” Consult a plumber. In certain locales, rising groundwater infiltrates the basement through the foundation. Installation and maintenance of a sump pump is critical.
