"Takes for ever to get a return a call. Also took a week to get someone out for repairs. They said they would reimburse me for septic repairs and it took over 3 months for that to happen."

Septic Tanks questions, answered by experts

Drilled wells have a pipe sticking up that’s covered in a plastic or metal casing. On the other hand, a dug well will look like a big hole in the ground and is more similar to what you’d see in a fantasy or Western movie. If you want to be sure, contact the city for documentation on your property’s construction and excavation history. 

Yes. A metal detector is one of the quickest and easiest ways to find your septic tank. However, metal detectors can be too expensive (costing upward of $300 in some cases), and not everyone has a metal detector just lying around. If that’s the case for you, you can also take a long metal rod and poke it into the ground at regular intervals until you hit something—likely your septic tank lid.

A septic smell may be harmful because sewer gas is dangerous depending on the exposure amount and length of time. Sewer gas is made up of multiple gases, including hydrogen sulfide, methane, ammonia, and carbon dioxide. Some of these gases, like hydrogen sulfide and ammonia, are toxic to humans and can be fatal in high concentrations or long exposures.

A septic alarm can sound different depending on your system, but often, it’s a loud, repetitive beeping noise or a steady, high-pitched noise. It may also be a loud buzzing noise. To confirm the noise is your septic alarm, check your alarm box for a red light. You can also silence your alarm with a red button or switch on the box. Look for something that says “Test” or “Mute.”

You only need to pump the septic tank. The leach field allows the liquid and waste to naturally seep into the ground, so there’s no need to pump the leach field. You should call a local septic tank pumping service to remove the materials from the tank every three to five years. Without pumping the septic tank occasionally, solids could flow into the leach field pipes and clog them.
