How to Tell if Your Drain Field is Failing

How to Tell if Your Drain Field is Failing

Having well-functioning plumbing systems is essential for any homeowner or business. One crucial component of this system is the drain field. It is responsible for filtering wastewater from your home or business before it enters the soil and groundwater sources. However, drain fields can develop problems over time, leading to expensive repairs and potential health hazards. In this blog, we will show you how to tell if your drain field is failing so that you can take action before it's too late.

Slow Drains

A slow draining sink or shower is a common sign of a drain field problem. When the field is failing, water and waste will build up in your drains, making it harder for them to empty quickly. If you notice that water is taking longer than usual to drain, even after using drain cleaners, you might have a drain field issue.

Foul Odors

A sewage smell is a clear indicator that your drain field is not functioning correctly. A failing drain field will release wastewater's odor into the air, causing a potent stench that spreads around your property. If the scent is particularly strong, you may need to call in a professional plumber to fix the problem.

Wet Spots in Your Yard

A drain field involves an intricate system of pipes working together to remove wastewater from your property. If any of these pipes get damaged or clogged, the water will be redistributed into your lawn. The accumulation of water will create wet spots that remain in the same area. These wet spots are an indication that your drain field is not working correctly.

Lush and Green Grass

On the other hand, you may notice an area of the lawn that has lush, green grass and grows more quickly than other parts. This happens because the wastewater saturates the soil, releasing valuable nutrients. While this may seem like a good thing, it's an indication of a failing drain field. The nutrients present in wastewater pose significant health risks if they find their way into groundwater sources.

Backup in Your Home

A clogged or backed-up drain is never a good sign, and it could be an indication of an issue with your drain field. If toilets are backing up, sinks won't drain, and water doesn't flow correctly, there could be a severe problem with your drain field. You should call a plumber immediately as this type of problem can lead to costly repairs and even exposure to harmful bacteria.


If you notice any of these signs, it's time to call in a professional plumber for assistance. Ignoring these problems will not only lead to expensive repairs but could also become a health hazard. Routine maintenance and checks can help prevent costly repairs and keep your plumbing system functioning optimally.
