"David McIntyre with Advantage showed up to assess a low water-leaking kind of noise in the toilet of my deceased mothers master bathroom.   I had initially checked to possibly replace the flapper, but then immediately called a professional when I saw all of the ancient American Standard Vent-away technology inside the tank.   After checking things over, David recommended replacement with modern water-saving toilet, giving me a number of good reasons, including a $75 incentive by the Woodmore association when converting to new 1.2 gpf toilets.   I purchased the Kohler one-piece toilet and David picked it up at Home Depot, brought it to the house, brought it in and installed it in a little over 1 hours.   While David was working, he noticed a small dripping with the toilet supply valve and replaced it with the supply line (all at no extra charge).   He discussed the slow leak and the damp carpet in the bathroom.   I told him that all of the outdated carpet was being replaced upstairs and that different flooring would be going into the bathrooms and the kitchen area.   He said "OK" and then advised me about getting a fan to deal with the moisture in the carpet until it was removed and replaced.   He then gave me some tips related to the use of the new 1.2 gpf toilet.   Overall the experience was excellent.   I was informed before, during and after the whole project.   The work proceeded quickly with no hitches and David cleaned up afterwards and disposed of the old toilet.   And the price was great.    I have been using it for a month now and it has worked like it should.   I am very happy.

"Jason saved me 4,000 dollars because of the thoroughness of his work. He noticed the home had Poly Butylene pipes. When I brought this to my realtor, she talked with the seller and he agreed to cut a check at closing for 4,000 dollars to cover the cost of replacing the pipes. Other than that, there were some other things, like a gas leak, that Jason was able to find. My realtor said they had never seen an inspection report so thorough."

"Fantastic! Snaked and scoped the sewer line and found that there needed to be a clean out installed. Went and got the parts and did it right then, working into the dark hours in the middle of winter. He came out the day that I called him, after all other companies in the area stated "nothing could be done". I would recommend him over and over and over again! He also charged the most fair price as anyone in town and provided higher quality and better services than they were."

Septic Tanks FAQs, answered by experts

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.

Over time, your septic tank can accumulate a buildup of sludge at the bottom of the tank. If left unpumped and uncleaned, the sludge will back up into your pipes and home, causing failure and extensive (and smelly) damage. Repairs to your septic system can be costly, which is why regular maintenance is required. It takes about 30 minutes to pump a septic tank that’s 1,250 gallons or less or 1 hour for larger varieties.

A properly installed and maintained septic drain field (also known as a leach field) can last up to 50 years, though the average is around 20 years. However, factors like poor soil conditions, heavy usage, or improper maintenance can significantly shorten its lifespan to 15-20 years.

To extend the life of your drain field:

  • Schedule Regular Inspections: Have the entire septic system, including the drain field, inspected every two to five years to catch problems early.

  • Protect the Area: Avoid driving heavy vehicles or placing heavy structures over the drain field. Plant only grass or other lightweight vegetation with shallow roots over the area.

  • Maintain the Septic Tank: Proper care of the septic tank, including regular pumping and avoiding harmful chemicals, prevents strain on the drain field.

Be aware of signs of failure, such as strange odors, standing water, or unusually lush grass over the field, which indicate your system may need professional attention.

If you aren’t sure if you have a septic tank or a cesspit, you can check your property records or inspect your drainage system. A septic tank has an outlet pipe that allows liquid to drain into a soakaway or drain field, while a cesspit is a sealed tank that requires frequent emptying. If you notice a manhole cover and no nearby drainage field, it’s likely a cesspit. Signs like slow drainage or a frequent need for pumping can also provide clues. A professional inspection is the easiest way to confirm if your home runs on a septic tank or cesspit.

Septic tanks come in multiple shapes, sizes, and materials. However, they’re often round or rectangular in shape and made from concrete, fiberglass, or plastic. There’s a range of septic tank sizes, with the average model measuring 30 to 40 square feet and holding 1,000 to 1,500 gallons of waste.
