Septic systems are a common way for homes not connected to municipal sewer lines to treat wastewater. With proper maintenance, septic systems can last for decades. However, many homeowners are unaware of potential issues with their system until it’s too late. Checking for certain signs regularly can help catch problems before they become expensive septic system repairs. Here are 5 key things to look out for that could indicate your septic system needs repair or replacement.
Soggy or Standing Water above the Drain Field
One of the most obvious signs is soggy or standing water above the drain field. The drain field, also called the leach field, is the area where wastewater flows from the septic tank and is absorbed into the soil. If the soil above the drain field is constantly soggy or water pools on the surface, it may mean the drain field has become overloaded, backed up, or blocked. This means wastewater is no longer properly absorbing into the ground as it’s meant to. Untreated sewage surfacing in the drain field area needs immediate attention from a professional for septic system repairs.
Sewage Odors Inside or Outside the Home
A strong sewage odor inside the home, near the septic system, or coming from the drain field indicates a serious problem. Wastewater should travel safely underground with no detectable odors. Strong odors could mean a blockage preventing wastewater from flowing properly or a leak allowing sewage to escape. Odors require tracking down by a professional to determine the source and perform any necessary septic system repairs before health risks increase. Minor occasional odors may be due to factors like temperature but consistent strong odors should not be ignored.
Slow Drainage of Sinks, Showers, Toilets or Bathtubs
When wastewater travels slowly or backs up in sinks, showers, toilets, or bathtubs, it could mean the septic system is overloaded or partially blocked. This is one of the early signs of issues as non-treatment of wastewater can then begin to occur. Check each fixture and look for slow draining over several drain cycles versus immediate emptying. Catching drainage problems early allows for less extensive septic system repairs versus a complete backup or failure.
Soggy or Wet Spots in the Yard
Like with the indicator above, soggy spots, bright green spots of grass, or depressed areas in the yard, especially near or over the septic system components could be a warning that wastewater is surfacing or the drain field is overloaded. Look for these signs, especially after rains or watering, to check for surfacing sewage before it contaminates more of the property or groundwater sources. Soggy spots require isolating the cause through a specialist or repairs may be needed.
Ponding around Structures or Driveways
Some pounding after rain is normal, but pooling of water that doesn’t fully drain away around structures, driveways, or patios over the septic system could be a sign leach lines are backing up or saturated. Check that water isn’t standing continuously in low areas as this could reflect an overload or blockage. A drain line television inspection by professionals may then be needed to locate problem spots for repairs.
