Finding the Source of a Kitchen Water Leak

Finding the Source of a Kitchen Water Leak

Have you suddenly stumbled across a pool of water in your kitchen? You’re not the only one scrambling to Google to find out why, and what to do about it. That’s why our team at POM Plumbing has put together a short list of causes to help you sniff out the source of your kitchen water leak.


The first place to check is the sink. The faucet is the easiest to rule out. If there’s a mystery puddle on the kitchen floor, unless your sink is backed up and overflowing, the faucet couldn’t have caused it. However, the drain and water line are both suspect. Open the cabinet beneath your kitchen sink. If all seems dry beneath it, you can move on to the next appliance. However, if there’s water pooled inside the cabinet and spilling out of it, it’s time to look further. 

If the water pooling is substantial, it’s most likely the water line, since it would take a steady stream of water coming in for anything more than a puddle. If the water line is broken or leaking, you need to turn off the water to the sink. There should be a knob on the wall at the back of the cabinet. Turn it as far to the right as you can. If the water doesn’t stop leaking after ten seconds, you’ll need to turn off the water main, which is likely located in the garage.

If the water line doesn’t seem to be the problem, and you can see a leak coming from your drain pipe, put a bucket or towel under it and give us a call. No matter which sink issue is leading to a leak, we’re here to help.


The first thing to know is whether your fridge has a water or ice dispenser. If it doesn’t, and the puddle is slightly sticky, it’s probably coolant leaking from the fridge. If that’s the case, you’ll need to buy a new one. Freon leaks can be dangerous, especially since it’s in the vicinity of your food.

If your fridge does have a dispenser and the liquid is almost certainly water, the next thing to rule out is the ice dispenser. Ice dispensers sometimes get ice stuck in the little trap door that opens to dispense the ice. After a short while, it will melt enough to slip out of the trap and then melt on the floor. This doesn’t happen infrequently, so you should be used to it unless you’re new to having a dispenser fridge. Check if there are ice chunks sitting in the puddle, or if the puddle comes out from under the appliance. If the water seems to be coming from beneath the fridge, you’ll need to call a fridge repairman or consider replacement if the issue continues.


If neither the fridge nor sink seem to be the obvious source of the water, it’s most likely from the dishwasher. Dishwashers leak water more often than either of the other appliances by nature of how much water runs through it regularly. If your dishwasher seems to be the culprit, check out this guide on figuring out the cause of the leak.
