Septic Tanks questions, 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.

To keep your septic tank healthy, be careful of what you flush and be conservative with water usage, as even flushing too much water down the drain can throw off the septic system’s delicate balance. Never flush anything but human waste and toilet paper down your toilet, and be sure to have the tank inspected and pumped every two to five years, depending on the size of your household and your water usage.

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.

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.

Yes, you can adjust your well pump pressure relatively easily by yourself. You’ll need to remove the cover from your pressure switch and adjust a nut that controls cut-in pressure. Learn more about how to adjust a well pump pressure switch with a step-by-step guide to setting your water pressure.
