"My daughter had a back water valve fail at her house. She had sewer water coming up the basement drain. JD called me within minutes of my inquiry on Angie's list. He was the first one to call and I'm glad he did. He was very patient and explained everything, took pictures and helped us every step of the way. I also appreciated knowing that he had daughters. This is my daughter's first home and it is hard to find someone to trust."

"The first visit was to replace my water heater. He asked how I liked my Sanyo air conditioning (wall mount deliver, condenser outdoors) I replied that there were great but they leak. He told me they could fix that. So second call was to fix my leaking air conditioners. In both cases the workers are prompt , professional , very helpful. These guys are not cheap but I think there prices are fair market value and they do great work.

Septic Tanks FAQs, answered by experts

Modern septic tanks have two lids: one that covers the inlet where wastewater flows into the tank and one that covers the outlet where the treated water flows out to the drain field. However, older septic tanks installed before 1975 may have only one lid. Because septic tanks last 20 to 40 years, if yours only has one lid, it may be time for a replacement.

The smallest septic system available for purchase typically includes a 750-gallon tank. However, the smallest size you can legally install is determined by local regulations, and many areas require a minimum capacity of 1,000 gallons. The cost to install a small septic system generally ranges from $2,910 to $13,900. Before proceeding, it is essential to check with your local health department or consult a local septic professional to confirm the minimum legal requirements in your area.

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.

The best bacteria to add to a septic tank is anaerobic bacteria, which doesn't use oxygen to break down solid waste. Because there is less oxygen in a septic tank, anaerobic bacteria can decompose sludge in a sealed environment. On the other hand, aerobic bacteria need oxygen and are prevalent in the leach or drain field of a septic system.

We’ve explained how deep-rooted plants can damage a septic tank from the outside, but plenty of things can ruin it from the inside, too. For example, flushing bulky items (like paper towels, diapers, and wipes) can clog your septic tank. Cooking oil, grease, and household chemicals can also harm your system. And since a new septic system costs between $3,460 and $11,450, it’s worth following these guidelines.
