"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

For the most part, choosing between 30/50 psi and 40/60 psi is based on your water-pressure preference. However, it can also depend a little bit on your house—if you have older plumbing, a lower water pressure can be easier on the pipes (and a bit more gentle on your well pump). 

The lower 30/50 pressure is usually enough for a single-story home, but you may want 40/60 if you have multiple stories, as the extra pressure helps water flow smoothly up to the second floor.

An outdoor water valve typically has a round or oval handle that you can turn to control the water flow. It may be located in a protective box or pit near the property line, where the main water line connects to your house.

Getting well water tested costs $100 to $350 if done by a pro. You can also buy DIY test kits for $20 to $100, but professional tests are more reliable. You can get a comprehensive well inspection, which includes advanced water testing, for $700 to $750, which you should do yearly anyway.

Yes, shower water goes into the septic tank. Shower water is a type of greywater, and in fact, all water used in a home with a septic system—including water from sinks, toilets, the dishwasher, and the washing machine—drains into the tank. When shower water enters the tank, debris like soap and hair travels with it. The solid debris sinks to the bottom to become sludge, while soap residue joins the scum layer at the top. The remaining water is treated in the tank before moving to the drain field for further treatment and dispersal. It is important to avoid putting oil or harsh chemicals down any drain, as they can cause clogs or disrupt the beneficial bacteria required for proper wastewater management in the septic system.

The size of your septic tank plays a role in determining the proper size of the drain or leach field. As a general rule, you should have 1 square foot of drain field size per gallon of septic tank capacity. However, you could install a leach field that’s as much as 2.5 square feet per gallon of septic tank capacity. Most professionals determine the right septic tank size and drain field size by the number of bedrooms in the house. A three-bedroom house needs a minimum 1,000-gallon septic tank, for example.
