"I hired them because they said they could pump my septic AND snake my drain. They did pump my tank very nicely, they were available when I needed them, and they were able to identify a problem immediately. However, what they meant by snaking the drain is that they could send another person out for an additional fee to snake the drain. I was also only quoted for the pumping and not the snaking so I ended up paying double what I thought I was going to pay. I also found out AFTER the first payment/job that they had a military discount so that was a little disappointing, but I am very grateful that it was applied to the second payment/job."

"We needed repairs from our septic tank to the distribution box and they were recommended to us. They did a great job explaining where the likely issue was and gave us a very fair quote. When it came time to do the job, he ran into a couple of unexpected old cable lines and irrigation lines and carefully worked around them. I would definitely recommend them for anyone looking for septic or excavation work."

Septic Tanks questions, answered by experts

A gurgling toilet usually doesn’t mean that your septic tank is full. If waste can’t drain into a full septic tank, you’ll see water and sewage backing up into your fixtures, but the air that causes gurgling is a result of poor venting. You are more likely to have a clog in your vent stack or a damaged air admittance valve.

If you’re going away on vacation or leaving your home for a long time, it’s a good idea to switch off your well pump and pressure tank before you go. This way you can prevent any damage from unexpected leaks that may occur or unforeseen electrical issues while you’re away.

A new water well pressure tank costs $300 to $500. If you choose to hire a plumber for the job, expect labor to cost $125 to $200. If the tank is difficult to access, labor will cost more. Diaphragm and bladder well pressure tanks have similar costs. One-compartment well pressure tanks are less costly, but they have a higher chance of waterlogging. Larger pressure tanks cost more and hold more water, but they don’t increase water pressure.

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.

A septic smell may be harmful because sewer gas is dangerous depending on the exposure amount and length of time. Sewer gas is made up of multiple gases, including hydrogen sulfide, methane, ammonia, and carbon dioxide. Some of these gases, like hydrogen sulfide and ammonia, are toxic to humans and can be fatal in high concentrations or long exposures.
