"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

When your septic system is failing, you’ll probably smell it. Common signs of a septic system failure include sewage odors in the home or around the yard, flooding in the yard above the septic tank or in the leach field, and wastewater or even raw sewage backing up into your home’s drains.

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.

Since vinegar is a weak acid with a pH of two to three, it’s generally safe for septic systems. It won’t eat away at the good bacteria in your septic tank and can help break down the sludge, which is its bottom layer. However, like with everything in life, moderation is key.

The water refills in a well through gravity that draws water from the water table to fill the vertical hole. The pump brings the fresh water through a pressure tank and to the pipes in your house. The well continues to refill indefinitely as long as you don’t use more water than the well is producing.

Septic drain lines (or leach lines) are typically buried between 18 and 36 inches underground, and should be at least 6 inches below the surface. These pipes are perforated and surrounded by filtering materials like sand or gravel. Burying the lines at this depth helps minimize odors and allows bacteria and other biological processes in the soil to effectively treat the wastewater. Burying lines too close to the surface can cause issues unless the soil is very compact and stable.
