How do you know if you have a slab leak?
10 Tips to help you determine if you might have a slab leak.
By their nature slab leaks may not become apparent for quite some time. Slab leaks do however have signs that you can see, feel or detect without playing whack a mole with a jackhammer to your foundation.
1. If you have started to notice moisture or mildew underneath your carpeting or if you see cracks in your tile floors or bubbles in your linoleum floors, this could be a sign of a leak. As the water from a leak starts to collect, it has nowhere to go but up.
2. Usually, hot water line leaks are discovered sooner, because you can feel them right under your feet! If you start to notice that one particular area of your floor is warm, it could be a sign that a hot water line is leaking underneath your slab.
3. If you have better ears than mine and listen carefully, you may be able to hear the hissing or splashing sound of running water.
4. If you see cracks in your baseboards or walls, it could be a sign of a slab leak. Since your slab is one single piece that’s made of concrete and steel, it doesn’t give at all. A leak can cause the entire thing to shift. As your foundation shifts, it will start to impact your entire home – even walls and floors that are nowhere near the leak.
5. If it seems like your pool is constantly losing water, you may have a leak.
6. If your water pressure has suddenly gotten very low, it could be a sign of a slab leak. Many slab leaks occur in the main water line – or where the water flows into your home from the outside. If there is even a tiny leak in your water line, your water pressure will drop significantly.
7. If your water bills have skyrocketed all of a sudden – and you have no idea why – it could be a sign of a leak somewhere. The damage from slab leaks can add up quickly; a pinhole-sized hole in one of your pipes can leak out more than 10,000 gallons of water in just one month!
8. See what your water meter is doing. Make sure that all of your faucets are turned off, that the toilet is not running, and that the washing machine or dishwasher is not on, go outside, and take a look at your water meter. The dial should not be moving. If it is, you likely have a leak somewhere.
9. Check your leak detectors. Some water meters have leak detectors inside of them that look like a small black or white triangle or wheel. If it is spinning – or moving at all – it means that you have a leak somewhere.
10. Check your water meter reading. Make sure there is no water running anywhere in your house, then go outside and read the numbers on your water meter. Leave all the water off for at least half an hour, then check the numbers again. If the number has gone up, you’ll know you have a leak somewhere. And, the higher the number climbs in that half hour, the bigger you’ll know your leak is.
