"Bill was great from the get go, he came right over and gave us solid professional advice on what we would need to do and how to go about it. Once it was determined that we would need to replace the septic tank which was an old metal tank that not only had not been used for more than 25 years, it was on the verge of completely failing. Bill took care of everything with the county board of health and the township who required a larger tank than the county. Our install turned to be a lot more work than he originally bargained for. He did not anticipate the amount of buried rock (large- boulders) in the area needed to enlarge a hole for the new 1500 gallon tank. He ultimately hauled out 5 loads of rock (boulders) and had to bring in several loads of crushed cement for fill to replace the boulders and to fill in and around the new tank, level up under and around the new lateral line to seepage pit. Bill was a total professional from start to finish, even with the set back caused by all of the stone, he was able to get right into the project and get the installation completed, since it did not require any new engineering or an expanded field he was able to get the inspection done right away which allowed us to keep the house on the market, and hopefully a new owner will be able to utilize the new system and enjoy the home for many years to come. I would highly recommend William (Bill) Farley Septic Services to anyone looking for a professional septic contractor any day of the week..."

"Scott and his sons were able to completely replace my failed septic in time for the sale of my house. It was an enormous amount of work in a very tiny space and I'm still amazed it was done so quickly. Scott updated us daily with where we were at with the process and kept on top of everything. I highly recommend Sunrise Environmental."

Septic Tanks FAQs, answered by experts

Most professionals recommend that a deep well pump shouldn’t run more than 10 hours consecutively before cycling off. Overworking the well pump beyond the recommended amount can prematurely wear out your pump and burn out the motor, which means replacing it more often than you otherwise should need to. Your well pump should also come with the manufacturer’s use and maintenance recommendations that are specific to the model.

How do you set your well’s pressure tank? All you need to do is first drain the tank of water and find the pressure switch. Remove the switch cover and adjust the switch with a wrench—clockwise to increase water pressure, and counter-clockwise to reduce it. Each complete turn of the nut on the switch should equal 2.5 psi. Once this is done, replace the switch cover. All that’s left is to adjust the pressure of the tank itself using an air compressor and a tire gauge to support the new setting.

The average three to four-bedroom home typically uses a well pump rated for 8 to 12 gallons per minute (GPM). To find the most accurate size for your specific needs, a common rule of thumb is to count the number of water fixtures and appliances in your home and aim for that number in GPM. This calculation allows for about one gallon of water per minute per fixture. Because estimating the correct size can be challenging, it's best to have a professional technician make the final determination. A professional can ensure your pump provides sufficient water for your home, especially during peak usage hours.

Septic tank locations are sometimes public record, although it depends on local laws and the property age. Older properties may not have the septic tank information on public record. To check, you can talk to local permitting agencies, such as your local health department, the local environmental department, or the county clerk.

Installation necessitates professional expertise due to complexity and to ensure safety when handling waste.
