"We needed repairs from our septic tank to the distribution box and they were recommended to us. They did a great job explaining where the likely issue was and gave us a very fair quote. When it came time to do the job, he ran into a couple of unexpected old cable lines and irrigation lines and carefully worked around them. I would definitely recommend them for anyone looking for septic or excavation work."

Septic Tanks questions, answered by experts

With regular testing, treatment, and maintenance, water from a community well should be safe to drink. Unfortunately, the EPA does not regulate private wells, and contamination can happen. 

If you have doubts about the quality and safety of your drinking water, you have options for testing. You can pick up kits from your local home supply store or harvest samples and send them to a local testing facility. To get the most complete water quality testing and system diagnosis, seek a local well professional. They know what to test for and can recommend and implement a longer-lasting solution.

Yes, shower water goes into the septic tank. Shower water is a type of greywater, and in fact, all water used in a home with a septic system—including water from sinks, toilets, the dishwasher, and the washing machine—drains into the tank. When shower water enters the tank, debris like soap and hair travels with it. The solid debris sinks to the bottom to become sludge, while soap residue joins the scum layer at the top. The remaining water is treated in the tank before moving to the drain field for further treatment and dispersal. It is important to avoid putting oil or harsh chemicals down any drain, as they can cause clogs or disrupt the beneficial bacteria required for proper wastewater management in the septic system.

With so much available information about the ecological effects of cesspools (and their general unpleasantness), it begs the question: Are cesspools legal? In short, sort of. Large-capacity cesspools that serve more than 20 people are completely illegal countrywide. Existing, smaller cesspools are generally allowed as long as they’re not actively polluting. However, new cesspools are illegal to build in all 50 states and Puerto Rico, and many states offer programs to help homeowners with the costs of updating cesspools to modern septic systems.

A new water well pressure tank costs $300 to $500. If you choose to hire a plumber for the job, expect labor to cost $125 to $200. If the tank is difficult to access, labor will cost more. Diaphragm and bladder well pressure tanks have similar costs. One-compartment well pressure tanks are less costly, but they have a higher chance of waterlogging. Larger pressure tanks cost more and hold more water, but they don’t increase water pressure.

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.
