"I called Pohlman to replace my Gas water heater. I was very pleased with their service. They were very professional, came out on the same day, took the old tank with them and cleaned up well behind themselves, They finish the job in a timely manner and their price was fair. I would definitely hire them again."

"The plumber was scheduled to come on 4/23 between 1:00 and 3:00p.m. At 1:00p.m. I got a call saying that the plumber would not be able to come until 4/24 as he was delayed at a previous call. He arrived promptly at 9:00a.m. the next morning. One toilet would not flush properly. He repaired that toilet. The other toilet ran on occasion. He replaced the fill valve. On occasion it still runs."

"After contacting five other contractors to repair a septic pump, Queen was the only one to promptly respond and follow through. The tech showed up on time, completed the job and charged a reasonable fee. I will use them for ongoing maintenance and would highly recommend them. I can t say this if many contractors ... totally satisfied with their work!"

"My call was returned promptly and the plumber showed up exactly on time. He was polite and fixed the problem very quickly and even gave me tips on how to avoid similar clogs in the future. This company truly cares about its customers which is a rarity these days and I will only use them for any future plumbing jobs. I highly recommend them, they are super!

Septic Tanks FAQs, answered by experts

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.

The physical constraints of hand-drilling a well limit the depth you can achieve. Manually digging with picks and shovels may only lead to shallow wells of up to 60 feet in depth. To reach greater depths, you need more specialized equipment. The diameter of your well and the tools you’re using will determine how far down you can dig.

Unlike an urban sewer system that runs wastewater into a central drainage system, septic tanks are a house-by-house system. They are the ultimate destination for all your house’s wastewater—from bathtubs, showers, sinks, toilets, and washing machines. Wastewater flows into a tank buried in the ground outside your home, and then water runs from the tank to a drainage field using sloped pipes.

While not strictly necessary for your septic system to operate, septic tank risers are a highly beneficial and wise choice for homeowners. They provide easy access to your tank, which makes regular maintenance, inspections, and addressing issues significantly easier and less labor-intensive. By eliminating the need for repeated excavation to locate the tank, risers can save you money, labor, and energy in the long run. This easy access allows you to proactively manage your septic system, addressing potential problems before they become costly and ensuring the system's longevity. Additionally, some local regulations may require risers, and installing them can help you avoid potential fines or penalties.

A household of four can easily fill a 1,000-gallon septic tank within a week. It may be 10 to 14 days for smaller households. But the reason why you don't need weekly pumping is because the tank's contents eventually reach the overflow pipe. They flow down this pipe to the absorption area whenever water is used in your home. The tank keeps working at this full level until it's pumped again.
