"Really glad i found Best Plumbing. Hired them to replace a shower pan and liked them so much that I had them replace shower doors and put in a new water heater as well. Fair pricing and always prompt, it felt like they went over and above what I was expecting. I would not hesitate to recommend Best Plumbing to anyone!"

"They arrived on time. Left the bathroom where the work was done clean. The job was done correctly and I haven't had any problems with their installation. There was a mistake in the billing - it was supposed to go to a different address and wasn't received so they added a late fee. When I called them about it they fixed it - I was happy. Note: The price charged included the cost of the new toilet, I had a sink and they were fine with installing that."

"The technician emptied the freezer, which was in the basement, to work on the part that needed repair. Then he neglected to put anything back into the freezer, including a turkey I had bought for Christmas and a rack of ribs. Two days after he left, I went out of town for two weeks. The turkey actually exploded and spewed its liquid all over everything, which had to be discarded. I let AHS know and they couldn't even bother to call me or follow up on this. I'm considering not renewing my contract with them because of the quality (or lack thereof) of many of the providers they send."

"Thank you (American Mechanical) for the excellent service you provided. We are extremely pleased with the holding tank installation and all the extra work involved in acquiring permits, county approvals etc., all done in a very professional manner. Every thing was completed in the exact time frame that you said it would be and we are very appreciative of that. If you want your job done right the first time then I highly recommend American Mechanical for your job. Sincerely, Dick K."

Septic Tanks questions, answered by experts

A septic system's lifespan typically ranges from 15 to 40 years, with a common average of 20 to 30 years. The longevity heavily depends on the tank's material, maintenance diligence, and usage habits. With proper care, lifespans can reach the upper end of this range.

Lifespan by Tank Material:

  • Concrete: 20 to 40 years

  • Plastic or Fiberglass: 30 to 40 years

  • Steel: 15 to 20 years

To maximize your system's lifespan, follow these maintenance best practices:

  • Regular Pumping and Inspections: Have the tank pumped every three to five years and schedule professional inspections regularly.

  • Mindful Usage: Only flush human waste and toilet paper. Avoid putting items like cat litter, paper towels, cigarette butts, fats, grease, oils, or coffee grounds down your drains.

  • Avoid Chemicals: Do not pour harsh chemicals into the system.

  • Water Conservation: Reduce the amount of wastewater your system has to process.

  • Protect the Drain Field: Avoid driving or building heavy structures over the drain field area.

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.

Beyond the type of well pump, there are a few other factors to consider when selecting a well pump. Keep in mind the depth of your well, your average water usage, and the PSI of your water-consuming appliances to determine the appropriate motor horsepower and size of your well pump.

There is no standard depth for burying a septic tank; they are typically buried anywhere from 4 inches to 4 feet underground. The final depth depends on several factors, including the depth of your main sewer line, the height of the bedrock, soil type, local regulations, and the property's landscape. If you plan to grow grass or plants over the tank, a depth of at least 4 to 6 inches is recommended. Deeper tanks can be more difficult to locate, but a septic professional can help find it for you.

A septic tank with a 1,500-gallon capacity is good for larger homes with up to 6 or 7 bedrooms. The average home can go with a smaller tank, about 1,000 gallons, which supports a home size of up to 2,500 square feet, or a home with about three bedrooms.
