Septic Tank Repair Cost

If you run into a serious problem with your septic tank, one of the first things that come to mind might be the cost. Unfortunately, most septic tank issues will be a minimum of $1,000 to resolve, although there are some exceptions to the rule. For any type of professional septic tank repair, the cost to repair a septic tank is between $891 and $1,434. The average septic tank repair cost is $1,397, but will vary from state to state.

Common Repairs

Price

Drain/Leach Field

$2,000 - $10,000

Baffle

$300 - $500

Tank Lid

$30 - $70

Drain/Leach Field

The drain or leach field is a section of your septic tank that carries the waste water back to the soil. The most common sign of drain field problem is your lawn becoming swampy and holding a sewage stench. The average cost to replace a drain field can be anywhere from $2,000 to $10,000, depending on your tank size and area your tank is placed.

Baffle

The baffle is the part of your septic tank that prevents scum and grime buildup in the inlet or outlet pipes connected to your system. Sometimes, replacing the baffle can fix the problem and won’t require the replacement of the tank itself. The average cost to replace a baffle is between $300 and $500.

Tank Lid

The lid of your tank is a very important part of your whole system, covering and allowing access to the tank itself. If you have a metal septic tank, the lid can rust over time and may need to be replaced. Replacing this part, compared to others, is one of the least expensive, ranging from $30 to $70. If you own a concrete lid, this will increase the cost to replace or repair, because special equipment will be necessary to remove the old concrete lid.

Septic tank repairs can be a complicated job depending on various factors, with materials and labor being the main influences. If your septic tank was installed on a slope instead of flat land, this will increase the cost of the overall job. Like the placement of the tank, if the ground in your area is frozen due to outside temperatures, this will also increase the cost. The harder the ground is, the more time and equipment will be needed to complete the job correctly. If the repairs become intensive and require more work, like digging up a large area of ground, the cost of the repair will go up.

Identifying Problems With Your Septic Tank

One of the biggest problems with septic tanks is that some homeowners don't actually notice the small problems until they have turned into much larger ones that become emergency fixes. Things to look for include:

  • Strong and unpleasant odors coming from toilets or showers in your home
  • Low water pressure or standing water above the septic draining field on your property

Importance Of Regular Inspections & Pumping

Although simply being on the lookout for problems is crucial, as mentioned above, it’s also important to have regular inspections for your septic system. We recommend hiring a plumber to inspect your septic system roughly once each year. In addition, you should have your septic tank pumped every three to five years or more frequently if you have a smaller tank or a larger family. Doing so can reduce the sludge and solids that can cause blockages and serious problems in the future.

When comparing the cost to maintain your septic tank and repairing your septic tank, you’ll find that maintaining your tank is the most cost-effective way to keep yours clean and running properly.

You’ll be able to tell due to the tank being full and the liquid level being higher than the outlet in the leach field. Also, another common repair is a broken pipe, which will need to be replaced to eliminate any standing and unhygienic water. If you notice any signs of a broken pipe, contact a sewer repair contractor and get an estimate today.
