"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..."

Septic Tanks FAQs, answered by experts

While dry wells can be effective for managing rainwater, they have several disadvantages. They can become clogged with sediment, especially after large storms, which reduces their effectiveness and can be difficult to clean. Dry wells are also not suitable for all soil types; they will not function properly in soil with low permeability. Additionally, if a dry well is not large enough to handle the amount of rainfall in your area, it can overflow. For gravity-flow models, the water may disperse very slowly, depending on the well's depth and the soil's permeability.

Most well pump pressure switches have a factory setting of 30 to 50 PSI. There’s some flexibility with this if you’d like a lower or higher water pressure, but remember that it should sit 2 to 3 PSI above your well tank’s general pressure setting.

The inside of your pressure switch cover will usually indicate minimum and maximum settings—going below and above the numbers might damage your well pump.

Depending on the size and location of your septic tank repair job, you may want to let the septic pros finish before tackling other backyard work. However, in some cases, it’s not a bad idea to coordinate between your providers if the timing’s right and your septic repair pro says it’s safe to do so. For instance, if the septic repair work is happening in the fall, you might want to take advantage of the opportunity to prepare your backyard landscaping for winter , or in spring, start mulching the garden beds.

Yes, a bigger well pump can increase water pressure—up to a point. If you currently have a well pump of 8 GPM, you might notice a pressure boost when you go up to 10 GPM. However, overshooting significantly (going up to 15 GPM for an 8 GPM home) can strain your well system and result in things like burst pipes that can decrease your water pressure and make for costly repairs.

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.
