"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

Yes, a septic tank riser can replace a concrete septic tank lid. Risers are designed to replace various types of septic tank covers, including concrete, metal, and fiberglass, to provide easier access for pumping and repairs. While a plastic riser makes future access more convenient, the initial replacement can be difficult because concrete lids are very heavy, so it is a job best left to professionals. Once installed, you will need to be cautious around the riser during yard work, such as mowing, to avoid causing damage.

A septic tank riser should extend to just above the ground level or slightly above it. The exact height can vary depending on local regulations and personal preferences, but a common guideline is to have the riser's top flush with or no more than a few inches above the surrounding ground. This height allows for easy access to the septic tank without creating a tripping hazard or obstructing mowing and landscaping activities. It's essential to ensure that the riser lid is easily visible and accessible for regular maintenance and inspection while being mindful of safety and aesthetics.

If your well pump is running continuously (meaning without turning off or stopping), it's a sign that your well pump is starting to break down. The length of time your well pump should cycle is dependent on many factors, like the tank size, pressure setting, and even the amount of water in your well. Generally, your well pump should cycle, or go from running to not running every few minutes.

You can add three rotten tomatoes or 1/4 ounce of yeast to your septic tank to speed up the decomposition of sludge. You can add the tomatoes by way of your garbage disposal and the yeast by way of your toilet. You can do either of these additives once every three months as needed.

You only need to pump the septic tank. The leach field allows the liquid and waste to naturally seep into the ground, so there’s no need to pump the leach field. You should call a local septic tank pumping service to remove the materials from the tank every three to five years. Without pumping the septic tank occasionally, solids could flow into the leach field pipes and clog them.
