"I called and got a friendly greeting. 
The service call came right on time and did a nice job.
i didn't have a problem but I had never had the cesspool pumped in 22 years.
OK, it was a brand new cesspool 22 years ago and my first house so I am really clueless.
I am told to pump it every 5 years so I guess I was over due. 
Not having a clue I only had an idea of what the cost was through the phone call I had made to the company. 
I was told $485 but was charged extra for aeration , chemicals and a tube going to the over flow tank. 
In total it was $750 with my Angie's List 10% off. 
Not to bad considering I never had it done before. 
Ray & Paul were very good at what they do, professional and got me up to speed on what was going on. 
I recommend using them!

"Review for Cesspool Services I recently had the pleasure of working with Cesspool R Us for our property’s cesspool maintenance, and I couldn’t be more pleased with the experience. From start to finish, the team demonstrated professionalism, expertise, and attention to detail that made the entire process smooth and stress-free. The technicians arrived promptly, fully equipped, and ready to get to work. They took the time to explain the process clearly and answered all of my questions, which was greatly appreciated. The work was done efficiently, and they ensured that the area was left clean and tidy, going above and beyond in their commitment to customer satisfaction. What really stood out was their knowledge and thorough approach. They identified and addressed potential issues I wasn’t even aware of, which saved us from potential future problems. It’s rare to find a company so dedicated to quality service and customer care. I highly recommend Cesspool R Us for anyone in need of reliable, high-quality cesspool services. Their team is skilled, respectful, and truly dedicated to doing the job right. Thank you for providing such excellent service!"

"Went well. Called for septic to be pumped on a Saturday afternoon. He was in the area on another job and came when he was done. Told us the overflow needed pumping also but would have to come back another day to do that since his truck was full. Got the septic pumped out and came back 10 days later to pump and aerate the overflow. Put the patch of grass back that he had to dig up to get to it. You'd never know he did anything there. Very pleased with his work. Bob was very professional, had told us the prices up front. Would definitely use him again. Price includes taxes and discounts from coupon."

Septic Tanks FAQs, answered by experts

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.

The smallest septic system available for purchase typically includes a 750-gallon tank. However, the smallest size you can legally install is determined by local regulations, and many areas require a minimum capacity of 1,000 gallons. The cost to install a small septic system generally ranges from $2,910 to $13,900. Before proceeding, it is essential to check with your local health department or consult a local septic professional to confirm the minimum legal requirements in your area.

The bacteria already present in your septic system should be enough to break down solids in a properly maintained septic tank. However, if you’re in a DIY mood, you can try adding (well-mashed) rotten tomatoes to help the good bacteria fulfill their duty. Just make sure you give them a couple hours to work after flushing them down.

The pressure in a well pressure tank should be set 2 to 3 PSI below the pump's cut-on pressure. The cut-on pressure is the lower number in the pressure setting (e.g., the '30' in 30/50 PSI) and is the point at which the pump starts. The cut-out pressure is the higher number, where the pump stops.

For example:

  • If your pressure switch is set to 30/50 PSI, the tank pressure should be 27-28 PSI.

  • If your pressure switch is set to 40/60 PSI, the tank pressure should be 38 PSI.

Common pressure settings for household applications include 20/40, 30/50, and 40/60 PSI. The difference between the cut-on and cut-out pressure is typically 20 PSI.

Most septic tanks can handle two to three loads of laundry per day, or a weekly total of between seven and 10 loads. Although septic systems do require homeowners to be somewhat careful with their plumbing systems—for instance, it’s not a good idea to flush a bunch of toilet paper all at once—they can still handle fairly heavy use.
