Where’s this water coming from… What’s leaking in my house?

When there is frequent water damage in a house, homeowners must determine what is causing the problem with an inspection from professional plumbing or water leak technicians. There are other reasons for moisture or water leak problems in a house besides a natural disaster such as a flooding river or lake. After flood water removal is completed due to tsunamis, heavy rainfall or flash flooding, the moisture from a home should not reappear unless there is another problem in the house that requires repair. Hiring an expert water leak detection service is the best way to determine where invading moisture is coming from before a home’s structures are destroyed completely. Water leak detection requires using state-of-the-art equipment designed to measure water usage in a house after all interior and exterior faucets are turned off for a certain amount of time.

Groundwater Seepage into Building Foundations

Common water leaks in a homes foundation can be caused by several factors, depending on the geographic location of the home. Natural causes for excessive moisture inside a home include groundwater seepage due to water sources nearby such as underground streams. Homes located along coastal areas are more likely to have groundwater seepage, but houses near other waterways are also susceptible. Newer homes are typically built using standards that prevent damage from invading moisture. The water from soil around the home enters lower levels such as cellar or basement walls to trickle down into a building’s foundation where it erodes wood and cement slowly. In many cases, the water entering the structure due to groundwater only occurs seasonally, allowing a massive amount of damage to happen before it is noticed by homeowners.

Slow Running or Clogged Sewer Lines

An additional reason for moisture problems in a home is from plugged or slow running drains or sewer lines, especially older systems. The raw sewage and filthy water from damaged sewer drains frequently goes unnoticed for long amounts of time, allowing moisture to decay wooden frames and cement foundations that support a building. Because the water is runoff from the house, homeowners do not notice any changes in utility bills to indicate there are leaks occurring. It can take years before the problem is noticed due to standing water in crawl spaces or on lawns. Not only are homeowners faced with the problem of correcting damage from invading moisture from this type of leak, there is also a danger from contamination such as viruses and bacteria that are in raw sewage.

Corroded Plumbing Fixtures

A house has a wide assortment of plumbing equipment that is mostly hidden inside walls and foundations instead of under bathroom and kitchen cabinets. Homeowners should inspect visible pipes, connectors and faucets located on the exterior or interior of a house for drips, corrosion or worn parts that indicate a repair is needed. Common water leaks in house plumbing that is frequently not noticeable occurs in pipes located in difficult to reach places such as behind bathroom walls near sinks, toilets or bathtubs. Homeowners may fail to inspect plumbing in dirty crawl spaces where pipes often split due to freezing temperatures in the winter. Failure to inspect and repair slow leaks from plumbing fixtures can lead to extensive water damage, including degrading cement house foundations.

Heating, Cooling and Ventilation Devices

Heating, cooling and ventilation systems in a home can also cause water leaks due to faulty drains and reservoirs that overflow slowly for many years. A worn valve that fails to close on swamp coolers or evaporative air conditioners can cause a stream of water to fill a plugged reservoir, leading to a leak in the wastewater system that causes moisture damage in unnoticeable areas. Central heating systems using forced air are often equipped with whole house humidifiers that are attached to ductwork and water lines to supply moisture in dry atmospheres. The water supply line’s valves may have defects that lead to moisture leaks inside walls of a house.

Water Meter Tests

In addition to flood water removal from homes, remediation professionals are able to detect leaks in a home with specialized tools such as meters. A water leak detection technician will turn off all water using appliances such as water heaters, dishwashers and clothes washers in addition to interior and exterior faucets before conducting a usage test. With sensitive meters, the technician determines if water is still leaking somewhere inside or outside the home. When water is leaking somewhere inside the walls or foundation, a home is in danger of having structural issues in the future such as corroded slabs, rotten wood frames or moldy drywall. In addition to checking for water leaks inside, there are often problems outside near water supply lines located deep underground.
