Q: How do you know when to empty a septic tank?

• <div><p>Most septic tanks need to be emptied every <b>3 to 5 years</b>, but it&rsquo;s a good idea to monitor the fill levels of your septic tank all the time.

Q: Do septic tanks clog easily?

• <div><p>Septic tanks can clog if they aren&rsquo;t pumped every few years since solid waste accumulates inside of them.

Q: What are the disadvantages of a mound septic system?

• <div><p>While mound septic systems can provide cost-effective wastewater treatment in many instances, they do come at a significant initial installation cost and require a lot of space on your property for the mound and its replacement field.

"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.
