"We bought a house recently. The inspection report called for installation of an expansion tank and lengthened drip leg on the HW heater. Jamison Plumbing had installed the new HW tank several months before for the original home owner. Jason called the City of Liberty to determine the exact code requirements. He called back and agreed to the additional work at no charge. He was able to make the changes in a timely manner. His crew called to say they would be later than planned because of an unexpected delay at the preceding job site. We appreciated his willingness to finish the installation according to code and to cover the additional materials and time. It was a great way to be welcomed into a new community.

"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 FAQs, answered by experts

Needing to pump the tank as soon as it “looks” full is a common myth about septic systems, as wastewater will eventually drain into the leach field. Instead, it’s better to determine how many solids have accumulated. A septic maintenance technician near you can test this to find out whether pumping is necessary.

A septic perc test is done by drilling a hole into the ground, filling the hole with water, and testing to see how long it drains. While simple, the test itself provides a great deal of information about your yard. The last thing you want to do is skip a perc test only to discover your yard doesn’t drain sewage effectively.

Septic tanks aren’t bad for the environment as long as they receive proper maintenance and attention. This means staying up-to-date with professional septic system inspections and septic tank pumping. Without regular maintenance, parts of the septic system could break or stop working, potentially letting harmful waste into the soil and groundwater.

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.

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.
