"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."

"**To everyone** This is the plumber you want to call !!! Typical FANTASTIC service call from "Knock You Plumb Out Plumbing". Our family was dead in the water, plumbing wise. We could not flush a toilet. Water was rising everywhere and all drains were gurgling. John Harris (owner), and a 2-man crew arrived 30 minutes after I sent a "Help!" E-mail to him. I could not believe he got to my home so quickly. John and his crew went to work diagnosing the problem. John started removing the plug on one end of my sewer system and found that my entire sewer system was under tremendous pressure due to all of the plunging I was doing. Before he started taking any more pipes apart in the basement, he asked if I had a septic system. I told him that I did and he said that my septic tank was probably full. John went out back, took the lid off of my septic system and found that the tank was almost completely full! Thanks to John, I then knew what the problem was and it was an easy fix. I had a septic cleaning company come out within a couple hours, and my house was back to normal. Thanks again John. This was the second time in 3 months he helped me out and I could not be happier. This guy is my only plumber?forever!

Septic Tanks questions, answered by experts

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.

The ideal depth of a septic drain field is 18 to 36 inches below the surface. The trenches must be deep enough to allow proper wastewater distribution and filtration while remaining shallow enough for oxygen to reach the soil, promoting bacterial activity that helps break down contaminants. In areas with high groundwater or poor drainage, shallower systems like mound drain fields may be required.

We’ve explained how deep-rooted plants can damage a septic tank from the outside, but plenty of things can ruin it from the inside, too. For example, flushing bulky items (like paper towels, diapers, and wipes) can clog your septic tank. Cooking oil, grease, and household chemicals can also harm your system. And since a new septic system costs between $3,460 and $11,450, it’s worth following these guidelines.

On average, you should call a pro to pump your cesspool once per year. If you have a larger home with a lot of family members, you may need to pump more (up to six times per year). On the flip side, if you’re talking about a cesspool for a home you don’t use much or if you’re the only occupant in a home, you won’t have to pump nearly as much.

You can cover a septic tank riser with dirt, but it’s not always the best idea. If you have a plastic riser and you bury it, you can easily lose track of it since you won’t be able to find it with a metal detector. Make sure to clearly note where your rise is in your yard so that you’re able to access it easily the next time you or a septic pro needs it. Don’t bury the cover too deep or you could place too much stress on it and make it too difficult to access in the future.
