3.     High water bills

Retrieve your water bill receipts from previous billing periods. Then, put each one side by side to see if there are significant increases in your water consumption.

Even small drips from a leaky faucet can waste more than 3,000 gallons of water in a year. When you multiply that loss by slow leakage from a burst pipe, you will notice significant spikes in the monthly water bill.

4.     Puddles under the sink

Another clear sign of a burst pipe is standing water or puddles under the sink. Puddles may form away from the actual source of a water leak, but they are usually due to an obvious pipe burst. These puddles can grow bigger and get through to other areas, such as the kitchen floor. Call a plumber immediately if you notice any puddles in or around your home. Even small puddles can indicate a serious plumbing problem. 

Aside from that, having puddles under the sink can cause a lot of problems. They range from these stagnant puddles being the home of mosquito larvae to other house pests. These pests bring diseases with them – posing a health hazard to you and your loved ones. What a headache indeed. 

5.      Fluctuating water pressure

Have you noticed varying water pressures at different points of your house during different times of the day? Observing fluctuating water pressure at home may be a sign of a pipe burst underground.

A burst pipe can cause a drop in water pressure, leading to a significant decrease in the amount of water coming out through your taps or shower head. While a fluctuation in water pressure could be due to the city’s fault, it might also be a sign of a plumbing problem. Get the issue fixed to prevent further damage when you notice a significant drop in water pressure.


A burst pipe can cause serious damage to your home if not identified and fixed on time. Reach out to a licensed plumber as quickly as possible and schedule an inspection for your plumbing system when you notice any of these signs. Besides fixing a burst pipe, an experienced plumber can advise on what might have caused the damage.
