"Excellent! Marty and his partner definitely know septic systems and how to evaluate their functioning level. We were very pleased and impressed with their knowledge, work ethic and the time they spent carefully checking every part of our system and explaining what they found to us. I will definitely use them again and tell neighbors as well. Several folks in my neighborhood tried going with the lowest bids on septic issues and all three had major repercussions! It pays to hire high quality people."

"Our existing septic tank was only a few years old, but the associated drainfield was failing and required replacement. Due to a small lot, our options were limited; but rather than a huge and unsightly bottomless sand filter, we opted for a less obtrusive (but expensive) treatment unit and pumps along with the needed replaced drainfield. Cory was very helpful in explaining complex options and costs."

"Professional, courteous, and even fun. Joshuah resolved the draining issues with two of our sinks quickly, expertly, and efficiently. He also gave us a tip to not use Drano, but use natural enzymes about once a month to keep the drains from clogging."

"Rob (the owner/operator) was very professional and helpful. He checked for new contacts when he finished his previous job in our town and called us before he headed home, allowing him to squeeze us in on a Saturday afternoon - in a thunderstorm! He then spent time with me while we were paying him, helping me understand how I could likely effect a solution to our septic system problems myself, without us having to even have him come out to pump our tank out again! I don t know how you get better service than THAT!! AND, his price was reasonable too! All-in-all, Enuf to restore your faith in buy American!!! Couldn t be happier he did work for us."

"Mike fully explained the job, pricing and expected end result. He specifically researched the model of my hot water heater so that he could give me correct details.  I wish my project had started with this call to Mike, it would have saved me time, money and frustration. It WILL be my first call for any future plumbing needs."

Septic Tanks FAQs, answered by experts

Bladder and diaphragm well pressure tanks are usually pre-charged at the factory. Even so, it’s important to check the air pressure in the tank using a tire pressure gauge on the relief valve. The instruction manual usually calls for 28 psi. Use a hand pump to add more air or release some air from the tank to reach the desired number. Check the pressure periodically to see if you need to add more air to the tank.

The smallest septic system available for purchase typically includes a 750-gallon tank. However, the smallest size you can legally install is determined by local regulations, and many areas require a minimum capacity of 1,000 gallons. The cost to install a small septic system generally ranges from $2,910 to $13,900. Before proceeding, it is essential to check with your local health department or consult a local septic professional to confirm the minimum legal requirements in your area.

Most well pump pressure switches have a factory setting of 30 to 50 PSI. There’s some flexibility with this if you’d like a lower or higher water pressure, but remember that it should sit 2 to 3 PSI above your well tank’s general pressure setting.

The inside of your pressure switch cover will usually indicate minimum and maximum settings—going below and above the numbers might damage your well pump.

Call a dedicated well and pump professional to install your new well pump. In some cases, plumbers may have the experience needed for the installation, but it’s always better to go with a specialized pro. Well and pump contractors have hundreds of hours of experience with all different types of wells and pumps. 

A gurgling toilet usually doesn’t mean that your septic tank is full. If waste can’t drain into a full septic tank, you’ll see water and sewage backing up into your fixtures, but the air that causes gurgling is a result of poor venting. You are more likely to have a clog in your vent stack or a damaged air admittance valve.
