"Within a few hours of submitting my search in Angie's List for a company to empty my septic tank, R&E Chief Septic called to schedule the appointment and provide me with the cost. I was surprised at the quick response and immediately set up an appointment. They were on time and quickly went to work. I will definitely use them from now on!"

"The plumber was scheduled to come on 4/23 between 1:00 and 3:00p.m. At 1:00p.m. I got a call saying that the plumber would not be able to come until 4/24 as he was delayed at a previous call. He arrived promptly at 9:00a.m. the next morning. One toilet would not flush properly. He repaired that toilet. The other toilet ran on occasion. He replaced the fill valve. On occasion it still runs."

"Excellent work. He covered his shoes while walking in the house. Before starting the project he analyzed the whole tubing route of the sink all the way to the basement. Cleaned up the whole area after the job was completed. Professional work ethics."

"Keon and his team were on top of it from the beginning. I was greeted well over the phone, and felt as if Keon was invested in my problem before being hired for the job. They were on time, very professionally dressed, and I felt their estimate was reasonable. As they explained the estimate, they were able to explain the why's of the estimate and give a rough estimate of the time it will take to complete the job. The quality of their work was outstanding. The care and craftsmanship that went into the install of the new supply lines can be easily observed. Supply lines were straight and parallel to one-another. They tested everything with me prior to and after cleanup, and made sure I was happy with everything before closing out the job. Definitive Plumbing and Heating takes great pride in their workmanship and relationship with their customers. They resolved all my issues, cleaned up behind themselves, and left my wife and I satisfied. At the writing of this review (about a month later) we have had no issues with the work and have received compliments regarding the layout design of the new supply lines. I would definitely use Definitive again for any plumbing needs, and I highly recommend them."

Septic Tanks FAQs, answered by experts

Soda, coffee, and other soft drinks are highly acidic. This affects the pH in septic tanks, causing them to require more frequent pumping. However, a vast majority of people don't need to worry about septic system disruption. Pouring out the occasional flat soda doesn’t affect septic systems to the same degree as the high-volume dumping from restaurants and convenience stores.

The disadvantages of having a well include more maintenance, like annual testing and inspections, and high up-front costs to drill a well. Well water is also vulnerable to contamination, which is why keeping up with testing is important if you own a well. When it comes to well water versus city water, well water does offer more independence and is a reliable water source.

It is not normal to smell your septic outside and indicates a problem such as an unsealed manhole or access lid, a clogged septic line, a faulty vent stack, or the need for a septic tank pumping. If sewage is leaking from your septic system, it can be hazardous to you, your family, pets, and the surrounding environment. You can troubleshoot the issue yourself, or contact a septic tank pro who can resolve the issue quickly.

Septic tanks aren’t bad for the environment as long as they receive proper maintenance and attention. This means staying up-to-date with professional septic system inspections and septic tank pumping. Without regular maintenance, parts of the septic system could break or stop working, potentially letting harmful waste into the soil and groundwater.

Over time, your septic tank can accumulate a buildup of sludge at the bottom of the tank. If left unpumped and uncleaned, the sludge will back up into your pipes and home, causing failure and extensive (and smelly) damage. Repairs to your septic system can be costly, which is why regular maintenance is required. It takes about 30 minutes to pump a septic tank that’s 1,250 gallons or less or 1 hour for larger varieties.
