Warning Signs of a Slab Leak
A Significant Increase in Your Water Bill
In many instances, our customers don’t realize they have a leak until they are shocked to find their water bill has increased by hundreds of dollars. While water consumption in your household may fluctuate from month to month, you should investigate for signs of a leak any time your bill increases unexpectedly above 15 % of your average. If you’re not seeing any signs of leak, and still have a high water bill it may still be a good idea to call us. Our licensed plumbers can inspect your lines with our top-of-the-line plumbing line locators and geophones to pinpoint the exact location of a leak. Remember, it is important to act with urgency when dealing with water leaks. Do not ignore a high water bill if you do not see a leak yourself. It could end up saving you tens of thousands of dollars if you call Reliant Plumbing right away.
Warm Spots on Your Floor
A telltale sign of slab leak is a persistent warm spot on your floor. This means a hot water line is leaking or busted. Oddly enough, your pets can actually be a great first indicator of slab leaks. We’ve seen that cats and dogs often enjoy laying on top of warm spots on the floor. Even if you aren’t finding any warm spots in your home, don’t write off a slab leak just yet. You could still have a leak in your cold water lines even though it is still 25% more likely to happen in your hot water line. A quick way to diagnose yourself, if you have a slab leak on your hot water lines would be to start at your water heater(s). Find the water heater supply line, turn it off for 5 minutes and do not use any hot water appliances in the interim. After 5 minutes, turn the water back on and if you hear a significant amount of running water then there is a good possibility you have a slab leak.
Swampy Areas in Your Yard by Your Concrete Foundation
When you’ve got a slab leak, the water has to go somewhere. If the leak is severe, water may begin to accumulate in your yard or around the edges of your home’s exterior. Any time you notice unexplained wet spots in your yard, you should call Reliant Plumbing to identify the cause. Do not confuse a swampy area caused by a water main break to a slab leak caused in your home. Often, the ground can shift where your water supply line is entering the home causing a break in the line underneath the foundation. This is a very common problem and a good indicator to tell the difference of what type of leak you have is to look for mold growing on the outside of your concrete foundation or finding visible wet spots on the soil or concrete. If you are experiencing this problem, call Reliant Plumbing to accurately detect and repair your leak today.
Damp or Musty Odors in Your Home
A more subtle sign of a slab leak is a persistent musty odor in your home that doesn’t go away even after a thorough cleaning. Water from a slab leak can seep into flooring and create a breeding ground for mold and mildew. You may not visibly see any damp spots or mold, but the odor can be an early warning sign that you should pay close attention to your plumbing. Call Reliant today and we can perform a pressure test on your domestic water lines to determine whether you are experiencing a plumbing or HVAC issue.
Sound of Running Water
In some circumstances, homeowners have actually been able to hear the water running out of the water pipes typically at the meter box or at the shower valves. However, this sound can be a symptom of many plumbing problems, so it’s best not to jump to conclusions. A quick way to determine if it is your domestic water line or irrigation system is to shut off the valve closest to the water meter box, also called a RPZ (Reduced Pressure Zone Valve Assembly). See the photo below for reference.
If you turn off the RPZ and your meter is still spinning, it is an indicator that you have a leak on your domestic water pipes. On the contrary, if your meter stops spinning then your water leak is coming from your irrigation system. Whichever side your leak is on, call Reliant Plumbing today and we will take this matter seriously.
Shifting Foundation or Ground
Major shifts in your home’s foundation can be a cause of slab leaks, but it can also happen in the reverse. Water is surprisingly powerful. As the ground beneath your home soaks up water from a slab leak, the ground expands and can cause severe damage throughout your home. If you notice new cracks in the walls or floors of your home, it can be a big red flag for a severe slab leak.
