"I just pay $75 you never know who's going to come out. They do everything electrical. Just about everything is covered except the septic tank. I had an air conditioner replaced. It went great, all I had to do was pay for the freon. He didn't charge e more than what was needed."

Septic Tanks questions, answered by experts

A cistern works by collecting rainwater from your gutters and downspouts and storing it in a holding tank. The holding tank can be installed above or below ground, and the size will depend on your household needs. The stored water can then be used for household tasks, watering your garden, and even for drinking water.

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.

Mound systems can fail if foreign objects are flushed into the septic tank, the septic tank is backed up with solid waste (sludge), if wastewater floods or seeps from the mound, or if any part of the system is clogged. To prevent this, only flush toilet paper and your normal “business” down toilets, and get a septic inspection at least yearly.

Since vinegar is a weak acid with a pH of two to three, it’s generally safe for septic systems. It won’t eat away at the good bacteria in your septic tank and can help break down the sludge, which is its bottom layer. However, like with everything in life, moderation is key.

Start by finding the septic tank, marked by an access lid near your home. From there, the drain field extends outward in a series of trenches. Look for greener, lusher grass, as drain fields promote plant growth due to moisture and fertilizer. You can also check property records, use a soil probe to detect damp soil, or hire a septic professional with ground-penetrating radar equipment to map the drain field’s location.
