"I hired Art to help level out my backyard, and unfortunately, I had a really disappointing experience. He started the job but left it incomplete and in worse shape than when he began. The yard was left uneven and messy, with piles of dirt scattered around and no clear plan for finishing. Communication was poor throughout, and despite several follow-ups, he never returned to complete the work. I regret hiring him and wouldn?t recommend his services to anyone looking for a reliable or thorough job. "

"We had a collapsed septic tank according to our home inspection. Bill Farley saw the urgency and had the tank replaced as soon as possible (a couple of weeks). He not only replaced the tank .. he repiped the inlets/outlets where the previous local company who serviced the tank had done it wrong. Bill was easy to deal with, fair and gets the job done the first time. Process was not stressful .. they takes care of everything and leave things better than before."

Septic Tanks questions, answered by experts

The average lifespan of a deep well pump is between 15 and 25 years, after which you’ll have to replace it. Several factors can affect the lifespan of a well pump, such as the quality of the unit. Proper maintenance and repair can also help extend your well pump’s lifespan as well as keep adequate water flow and pressure throughout your home.

Your septic tank naturally contains good bacteria, and you won’t really need to do much to put good bacteria in the septic tank. You can use additives like active yeast, rotten tomatoes, or store-bought septic enzymes or chemicals if you’d like, but typically, the system will produce beneficial bacteria on its own. The best way to keep that bacteria thriving is to avoid using chemical drain cleaners, which can kill off the good bacteria in the septic tank.

Choosing a reliable septic tank company starts by finding an experienced company in your area with positive customer reviews online. You can also use the following tips to help ensure you have a positive experience:

  • Choose a company that is licensed and fully insured

  • Ask the company for customer references

  • Ask if the company provides any guarantee for the repair

  • Determine the provider’s level of experience

You should pump your septic tank once every two to four years for a family of four, depending on your septic tank size. You should pump a 1,000-gallon septic tank every two years, while a 1,500-gallon tank should be pumped every four years. Water usage also affects how often you should pump your septic tank. If you notice slow drains, foul smells, or gurgling sounds from your drains, you should pump your septic tank as soon as possible.

A septic tank always has some amount of liquid in it—which should usually be 8 to 12 inches from the top of the tank. If the liquid level is higher than that or is overflowing the drainage pipe that leads out to the leach field, the tank may be too full and in need of pumping.
