"I had a drain clog that was becoming a real headache, and Sewer Surgeons took care of it quickly and professionally. The technician was friendly, showed up on time, and explained what was going on without making it complicated. The price was fair, and there were no surprises. The whole process was made easy and overall I would recommend them to anybody in a heart beat."

"I just pay $75 you never know who's going to come out. They do everything electrical. Just about everything is covered except the septic tank. I had an air conditioner replaced. It went great, all I had to do was pay for the freon. He didn't charge e more than what was needed."

Septic Tanks FAQs, answered by experts

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.

The efficacy of a drain field depends on a wide variety of factors, though a well-maintained one can last as long as 40 or 50 years. Of the different types of septic tanks on the market, concrete and plastic tanks tend to last the longest—upwards of 40 years if they’re pumped regularly—while steel tanks have a tendency to rust over time and may need to be replaced after 15 or 20 years.

It only takes a few days for a septic tank to fill with water after a pro has pumped it. This is completely normal, and the water is a vital part of your septic system’s wastewater treatment process. The water that fills your tank days after pumping is not the same as the tank being filled with waste. You shouldn’t have to pump your septic system more than once every three to five years unless you have a tank that’s too small for your home’s water output or there’s a problem with your leach field. 

Normally, when your well pump turns on or off, you’ll hear a small click. This isn’t anything to worry about, but it can be a problem if it’s clicking continuously. This can indicate that the well pump is short cycling—the pump continuously turns on and off.

This can wear out the motor and provide uneven water flow. If this happens, you may need to get it looked at by a well pump professional to see if you need to repair the switch or pump.

There are a lot of issues that can cause a septic tank to collapse. Those include failing to regularly pump or service it every three to five years, placing too much weight atop the system—by parking your car on top of it or because of a heavy snow buildup for instance—or because of structural damage done by overgrown tree roots.
