"They responded immediately and fixed the problem. While there we had them address a few other issues and they fixed them immediately and did not take advantage of us. We also had them come out in March 2013 because we were told that we needed a new well expansion tank by another company. They were honest and showed us that we did not need another tank. The tank was working fine. I would recomend these guys. They are good.

Septic Tanks FAQs, answered by experts

For homes with a septic tank, harsh chemicals like those found in drain cleaner or bleach aren’t recommended. Some chemical drain cleaners can disrupt the balance of bacteria in the septic tank or damage your pipes. For homes with a septic tank, you can choose drain cleaners specifically formulated for use with septic tanks or go with a drain snake. When in doubt, make sure you know who to call for a clogged drain. 

Most septic tanks can handle two to three loads of laundry per day, or a weekly total of between seven and 10 loads. Although septic systems do require homeowners to be somewhat careful with their plumbing systems—for instance, it’s not a good idea to flush a bunch of toilet paper all at once—they can still handle fairly heavy use.

There are many potential causes of low well water pressure. The most common include sediment buildup, leaking pipes, a failing well pump, or a cracked pressure tank. 

Costs depend on tank accessibility, size, and local rates. Regular service serves as preventive care, averting costly emergency repairs or system replacements.

Talking with a septic pro before planting trees near your tank is best to ensure the roots won’t interfere with your septic system. However, there is an easy way to figure out where to plant a tree—but you’ll need to know how tall it can get when it’s fully grown. For instance, if the tree can reach 50 feet, plant it at least 50 feet from your septic system.
