"They came out first to find the septic tank and then would have to come back with the pump truck to pump it. After utilizing the camera mechanism to locate the tank, we were advised that pumping wasn't really needed yet. They could easily have led us to believe it needed to be done, but they chose to be honest and save us the added cost. Honesty & integrity, i like that in a service provider!"

"I had a drain clog that was becoming a real headache, and Sewer Surgeons took care of it quickly and professionally. The technician was friendly, showed up on time, and explained what was going on without making it complicated. The price was fair, and there were no surprises. The whole process was made easy and overall I would recommend them to anybody in a heart beat."

Septic Tanks FAQs, answered by experts

If you’re going away on vacation or leaving your home for a long time, it’s a good idea to switch off your well pump and pressure tank before you go. This way you can prevent any damage from unexpected leaks that may occur or unforeseen electrical issues while you’re away.

Both materials are suitable for septic tanks, but concrete usually lasts longer than plastic. If you’re buying a new tank, the prices are similar for plastic ($500 to $2,500) and concrete ($700 to $2,000). However, there’s a notable difference in repair prices, with plastic tank repair costs ranging from $150 to $2,000, while concrete repairs are between $700 and $5,000.

Septic tanks and cesspits are both types of sewage and wastewater systems, but they differ in key ways. The main difference between the two systems is that septic tanks separate sewage from wastewater and allow the latter to flow into a drainage field to filter and disperse into the soil. Cesspits don’t have outlets and instead, store sewage until it needs to be pumped by a professional.

Buying a well drilling kit will save you money over hiring a professional. That said, digging a well is risky. If you make an error, you may have to get help fixing it. Also, the DIY costs are still pretty hefty when considering everything needed to complete the project successfully. You’ll need to account for the permit, pump, water tank, and more. If you don’t feel comfortable taking the necessary precautions to tackle this on your own, go with a pro.

How do you set your well’s pressure tank? All you need to do is first drain the tank of water and find the pressure switch. Remove the switch cover and adjust the switch with a wrench—clockwise to increase water pressure, and counter-clockwise to reduce it. Each complete turn of the nut on the switch should equal 2.5 psi. Once this is done, replace the switch cover. All that’s left is to adjust the pressure of the tank itself using an air compressor and a tire gauge to support the new setting.
