"Great experience Justin, Nate & Timothy were awesome. Very knowledgeable, professional & curious. Aside from the cleanliness they delivered an experience. I highly recommend HL bowman if you want rapid service on your HVAC. Pricing was reasonable in my opinion & financing is an option. Keep in mind when seeking quotes for your HVAC repair/ new install you must consider performance over equipment, that is if your want a good system that will have a good run/life span."

Septic Tanks FAQs, answered by experts

Baking soda does very little to nothing for a septic tank, but it can help unclog a drain or clean out a garbage disposal. Rotten tomatoes and yeast are the best ways to increase the bacteria in your septic tank naturally. You can add these to your system once every three months.

Your septic tank may be full or clogged if you notice household drains that are backed up, draining slowly, or gurgling; greener, lusher grass around the septic system; pooling water in your yard; or smelling sewage odors outdoors. You can contact a local septic tank pro to inspect your septic system and pump your tank.

Start by finding the septic tank, marked by an access lid near your home. From there, the drain field extends outward in a series of trenches. Look for greener, lusher grass, as drain fields promote plant growth due to moisture and fertilizer. You can also check property records, use a soil probe to detect damp soil, or hire a septic professional with ground-penetrating radar equipment to map the drain field’s location.

Septic tanks naturally have bacteria that break down some of the solid waste in the septic tank. However, sludge buildup is just part of owning a septic system. While liquid wastewater can be filtered and treated through the system, a septic tank company has to pump the septic tank out at least every few years.

With proper maintenance, most types of septic systems—including mound, evapotranspiration, and constructed wetland systems—can last up to 40 years. To keep your system running as long as possible, follow basic septic tank upkeep guidelines, like pumping your septic tank every three to five years and only flushing human waste and toilet paper.
