"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."

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

A submersible pump should be at least 10 feet from the bottom of the well to minimize the risk of the pump drawing debris into the well water. Submersible pumps work best for wells that are 25 feet deep or less. If you have a deeper well, choose a jet pump instead of a submersible model.

How to size a well pressure tank is determined by three factors: flow rate, or how many gallons per minute your well pump produces; minimum runtime; and pressure switch setting. Most pressure tanks have a pressure switch operating at 20/40, 30/50, and 40/60—the first number is the pressure needed for the pump to turn on, and the second number is the pressure needed for the pump to switch off. Most homeowners relying on well water require a water pressure tank ranging from 20 to 80 gallons. 

If there’s a problem with your sewage system, you might notice water pooling on the ground around the tank, which could indicate an overflow. Clogged and sluggish drains or foul smells coming from your plumbing are also signs that there might be a blockage in your septic system.

Watch for slow drainage, pooling water in the yard, or unpleasant odors inside or outside. Addressing these issues timely avoids significant disruptions or costs.

Perc rates vary dramatically, and a good perc rate could be anything from 5 minutes per inch of drainage to 60 minutes per inch. The lower the number, the faster your system will drain and the more effective it will be. A 60-minute-per-inch drain rate is the highest number considered to be good, or even allowable, draining.
