"My Septic pump had failed. I had already reached out to another septic repair company, but after 24 hours they still could not give me a day they would be available. I called Pavel at Earthworks Solutions and within 3 hours he had Dennis out there to replace my pump. He installed 3 risers and a new drainage pump all in the same day. Dennis did fast good work and I would recommend Earthworks Solutions."

"We got our working tank water heater replaced, it was 14 years old so about end of life. Due to COVID they asked for photos via text message, gave quote for exact product, suggested that expansion tank is on wrong side (we never knew), came on time, got the products, fixed the expansion tank and were done in less than 2 hours. Asked to clear the garage, maintained social distance, job perfectly done."

Septic Tanks questions, answered by experts

Unfortunately, yes. If your well pump continues working when the flow of water is completely blocked, the motor will burn up. The energy has nowhere to go, thanks to the blockage, so it turns inward. The end result? A ruined well pump and a depleted bank account (once you shop for a replacement.) 

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.

Septic tanks naturally have bacteria that break down some of the solid waste in the septic tank. However, sludge buildup is just part of owning a septic system. While liquid wastewater can be filtered and treated through the system, a septic tank company has to pump the septic tank out at least every few years.

Yes, it is generally okay to oversize a well pressure tank, and it will not harm your well system. The primary advantage is that a larger tank reduces frequent pump cycling, leading to longer, slower cycles with fewer startups. This can result in less wear and tear, potentially increasing the lifespan of the pump and conserving energy. However, there are drawbacks to consider. Oversized tanks have a higher upfront cost and require more physical space. While not necessarily a bad thing, opting for a tank that is appropriately sized for your well is often the most efficient choice in terms of cost and space.

Yes, septic tank companies must be licensed in most states and municipalities to perform services like installation, alteration, repair, and pumping. Since laws vary by location, it's crucial to check local requirements.

Hiring an unlicensed professional can lead to poor work, code violations, and significant fines. Always verify that your chosen company is properly licensed and fully insured to avoid liability. You can use tools like Angi’s contractor licensing search to check a pro's credentials.

It's also helpful to understand the difference between licensing and certification. A license is a legal requirement to operate, while certifications are voluntary. Credentials like the “Angi Approved” badge indicate that a business meets extra standards, such as passing a background check and maintaining a high rating.
