Water lines run at a minimum of 6 feet underground to prevent the pipe from freezing. Because of this, the waterline always enters the home at the lowest level. If this is a crawlspace, then enter the crawlspace and scan the side of the home that was determined in the previous step.
The only sure way is to drill or dig a well to find out. There's virtually always a little bit of water available if you go deep enough, but the amount that will flow into the well may be so small as to be entirely useless for all practical purposes.
Your water line must be buried at least 12 inches below the frost line to meet local code requirements. However, a minimum depth of 6 inches below the frost line is often recommended for extra security against freezing.
The reasons you might have standing water under your home include a clogged low-point drain, leaking pipes, cracks in the foundation of your home, issues with foundation vents, and moisture from the ground.
Professionals and plumbers use devices to detect where the water is leaking by using electrical signals underneath the ground. Using a pipe locator device is the most common way to detect underground water leaks. This device uses radio waves to detect metal pipes, making it easy to find and fix the leak.
Under most standard home insurance policies, if water damage occurs suddenly or accidentally from a source inside your home, such as a busted pipe, it will likely be covered by your homeowners insurance. If the water comes from outside your home, it will not be covered by your standard policy.
Today, the best tool for the job is ground penetrating radar (GPR) as it accurately maps metal and PVC pipes. Traditional pipe locators use electricity and magnets to locate underground pipes.
This means that you would typically want your water lines to be at least 4.5 feet below the ground level or possibly even deeper if you live in the mountains or the foothills. The sewer lateral leading from your house out to the municipal sewer main should also be at the same depth as it could also freeze.
The Lifespan of a Water Line
The mainline provides homes, particularly within a suburban or urban housing development, with running water. Typically, main water line pipes last decades. Some experts estimate that they last around 70 years, though this can vary from development to development.
The most reliable method of obtaining the depth to the water table at any given time is to measure the water level in a shallow well with a tape. If no wells are available, surface geophysical methods can sometimes be used, depending on surface accessibility for placing electric or acoustic probes.
It is important to note that under Public Trust, water resources “belong” by the public; property owners can't “own” water, but they may have the right to use, sell, or divert water resources, depending on the laws in the state. The two main types of rights are riparian and appropriative.
As solid as you may think your home's structure is, water will find every possible crack and crevice to enter. Over time, standing water can leak into your home, causing further water damage and leading to mold growth.
Every house has at least one main water shut-off valve. Look for where the plumbing enters the home to find yours. There are a couple of main spots to check inside first before heading outside to look. You can save yourself some time by checking your property inspection report if you know where that is.
You'll want to find where the service line enters your home—typically in the basement or crawl space, just prior to the shutoff valve. The water meter may be in the same location, but in some areas, the water meters are outside the home.
Typically, water lines are buried at a depth ranging from 18 inches to 5 feet, depending on various factors such as local climate, soil conditions, and the type of water system in place.
Perhaps the water pressure in your house isn't great or your water supply isn't healthy. If you find yourself in either of these situations, know that it is possible to replace a water main – the main pipe that supplies your water – entirely by yourself. You can also save yourself a lot of money in the process.
The line varies by latitude, it is deeper closer to the poles. The maximum frost depth observed in the contiguous United States ranges from 0 to 8 feet (2.4 m). Below that depth, the temperature varies, but is always above 0 °C (32 °F).
If your home has a basement or crawlspace, check there first. For homes built on a slab, check in the garage or near your water heater. The incoming water line usually comes through the foundation near the front side of your house. Follow this line up to the water meter.
What Will 811 Locate? When you call 811, the utilities that are publicly owned, operated, and maintained by the local municipality and or the utility company in your dig area will be located, including telecommunication and fiber optic lines, water lines, gas lines, power lines, electrical lines, and sewer lines.
Sand or gravel areas in the bottom of valleys will often be home to groundwater. These layers can be covered by clay or silt, so it's prudent to check these areas thoroughly. Natural springs usually indicate groundwater is nearby. A spring that flows year-round will likely reveal a productive aquifer.
If the break or hole in pipe occurred within your home's foundation, it may be covered., however, it is not likely that your policy will cover pipe bursts or breaks that occur outside of your home's foundation “footprint”.
As a general rule, water damage is covered by home insurance if it is sudden or accidental.
Dwelling coverage, on your condo or homeowners policy, may pay to repair or replace your floors and carpet if they're damaged by a covered peril. For instance, if your home's floors are damaged in a fire, your home insurance may pay for new flooring, up to your policy's limits and minus your deductible.
