"Excellent value. Superior work. We had multiple stumps removed, an old 16â x32â raised bed garden removed. One of the stumps was right next to our septic tank. JReid was able to remove this stump without harming our tank at all. This stump was within 1ft of the tank, and it was carefully removed with expertise. I would definitely recommend them!"

"This company called me as I clicked yes to help. Very knowledgeable, he asked me questions, figured out my problem and told me where to get part and pretty much how to install it and test it! He had prices, options and I will call him anytime I have water issues! The rest of the day I answered calls and was told I needed them to come and charge me tons of money.. I am up and running with a phone call! Almost nobody does that anymore. Satisfaction went through the roof with Drain Cleaners Sewer and Septic Professionals, they knew all about wells, pumps, tanks and control boxes! Love these guys! thank you again, Dean R. Hubbel"

Septic Tanks FAQs, answered by experts

It only takes a few days for a septic tank to fill with water after a pro has pumped it. This is completely normal, and the water is a vital part of your septic system’s wastewater treatment process. The water that fills your tank days after pumping is not the same as the tank being filled with waste. You shouldn’t have to pump your septic system more than once every three to five years unless you have a tank that’s too small for your home’s water output or there’s a problem with your leach field. 

There are three layers of wastewater in a septic tank: scum (solid waste that floats to the top of the wastewater), liquid (the relatively clean liquid wastewater in between the two other layers), and sludge (solid waste that falls to the bottom of the wastewater). The buildup of sludge is one of the main reasons septic tanks need to be pumped. If the tank is more than 1/3 of the way full with a combination of sludge and scum, it’s time to call a pro for pumping.

If you notice that your well pump runs continuously, it’s important to take action quickly to avoid further damage. A few common issues may be to blame for a continuously running well pump, such as mechanical damage, a faulty pressure control switch, low water level, prime loss, and leaking pipes and fixtures.

There are a few signs that indicate a failing drain field. For instance, if your septic tank starts requiring more pumping than normal, your drain field might be failing. Other signs to watch for include poor drainage after rain, standing water or sewage over the septic system, a strong septic smell outside, new and healthy grass growing over the drain field, and plumbing backups in your sinks, bathtubs, or toilets.

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.
