"John Bensavage did an excellent job of repairing my septic system which included replacing the septic tank. To gain access to the tank they had to have five trees removed. John coordinated the tree removal subcontractor as well as removing and replacing the septic tank. He also repaired the broken waste pipe leading to the septic tank. Throughout the whole process every phase of the job was performed on in a timely manner and every delivery of material arrived on site exactly when needed. John's crew was excellent as well, performing each phase efficiently and smoothly while while exercising great care to avoid damaging the adjacent structure. I enjoyed watching how smoothly they worked together. When the job was finished, they expertly restored the surrounding landscape to a condition better than it was before. John kept every promised date and time and accomplished the job exactly when he said he would. I highly recommend John H. Bensavage LLC to anyone in need of septic system repair. And John was the lowest bidder."

"Replaced a tank water heater, the door was too narrow so first pitched removing framing with no guarantee that it’d be replaced correctly. I suggested using a smaller sized unit based on a quote from another plumber which is the route we went. They also covered the overage for the additional cost of the smaller sized unit which was nice but if I wasn’t aware of the option I’m not sure what I would have done. They also only sent one person initially so I helped bring the old unit down and the new one up in between trying to work. Also the breaker to the hot water heater was never flipped back so I’m waiting to see how the unit performs now."

"I hired them because they said they could pump my septic AND snake my drain. They did pump my tank very nicely, they were available when I needed them, and they were able to identify a problem immediately. However, what they meant by snaking the drain is that they could send another person out for an additional fee to snake the drain. I was also only quoted for the pumping and not the snaking so I ended up paying double what I thought I was going to pay. I also found out AFTER the first payment/job that they had a military discount so that was a little disappointing, but I am very grateful that it was applied to the second payment/job."

"Ryan was professional, extremely knowledgeable, and thorough. He utilized a camera and quickly identified the source of the blockage and pumped the tank. We will definitely use OHala Sanitation to address any future problems and for our annual septic pump service."

Septic Tanks FAQs, answered by experts

For homes with a septic tank, harsh chemicals like those found in drain cleaner or bleach aren’t recommended. Some chemical drain cleaners can disrupt the balance of bacteria in the septic tank or damage your pipes. For homes with a septic tank, you can choose drain cleaners specifically formulated for use with septic tanks or go with a drain snake. When in doubt, make sure you know who to call for a clogged drain. 

A septic system inspection costs $100 to $200. Doing so can spot issues early so you can plan for necessary repairs ahead of time and save yourself the issue of a backed-up septic tank. Some septic tank repair professionals do an inspection as part of their yearly maintenance on your septic tank if you choose to pay for that service, but you should shoot to have a septic system inspection completed at least once every two to five years.

The average cost to replace a septic tank or install a new system is typically around $7,350, with a broader average range of $5,000 to $12,000. However, total project costs can vary widely, from $5,000 to as much as $22,500. Key factors influencing the price include the size and type of the septic system, the tank material, and the size of your house.

It's important to distinguish between the cost of the tank itself and the cost of the entire system installation, which is significantly more. For the tank alone, costs vary by size:

  • A tank for a one-bedroom house typically costs $500 to $900.

  • A 1,000-gallon tank, suitable for most one- to three-bedroom homes, costs between $900 and $1,500.

  • A tank for a five- or six-bedroom home generally costs $1,200 to $1,600.

Septic tanks come in multiple shapes, sizes, and materials. However, they’re often round or rectangular in shape and made from concrete, fiberglass, or plastic. There’s a range of septic tank sizes, with the average model measuring 30 to 40 square feet and holding 1,000 to 1,500 gallons of waste.

Perc rates vary dramatically, and a good perc rate could be anything from 5 minutes per inch of drainage to 60 minutes per inch. The lower the number, the faster your system will drain and the more effective it will be. A 60-minute-per-inch drain rate is the highest number considered to be good, or even allowable, draining.
