"Tony arrived at the agreed time. He was professional, courteous, and answered any and all questions I had. This is the second time I hired him to service/pump our tank (last time was about 2 years ago) and I plan to hire him again when our next service is due. His prices are competitive and his professionalism is top notch. I highly recommend him to everyone requiring his services.

"He did an excellent job replacing our septic tank. He solved a difficult problem with a huge boulder that was blocking the move of the tank. Also was very careful not to damage the rest of the yard during installation. Overall, job well done. Quality job at a fair price."

"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."

"He was on time, friendly, and honest. We had a plumber tell us that the pipe was broken at the septic tank so Phil and Mike came out to dig it up and replace it. When he dug it up he found that the pipe was not broken and was totally honest about it and gave us options and help that solved our issue we were having. I would totally use him again for any work I need done in the future."

Septic Tanks FAQs, answered by experts

There are a few signs that you might notice if your drain field is bad. For starters, if you see standing water or soggy grass above your drain field, it could mean that it isn’t working correctly. Or, if your yard smells like sewage, it could also indicate that there’s a problem with your drain field. Repairing a drain field costs an average of $2,000 to $15,000.

Yes, a bigger well pump can increase water pressure—up to a point. If you currently have a well pump of 8 GPM, you might notice a pressure boost when you go up to 10 GPM. However, overshooting significantly (going up to 15 GPM for an 8 GPM home) can strain your well system and result in things like burst pipes that can decrease your water pressure and make for costly repairs.

The ideal depth of a septic drain field is 18 to 36 inches below the surface. The trenches must be deep enough to allow proper wastewater distribution and filtration while remaining shallow enough for oxygen to reach the soil, promoting bacterial activity that helps break down contaminants. In areas with high groundwater or poor drainage, shallower systems like mound drain fields may be required.

The depth of your septic tank has nothing to do with its size. In fact, some septic tanks can even be installed above-ground! Like other sizes, a 1,000-gallon septic tank could be buried as shallow as 4 inches below the ground or as deep as 4 feet. It all depends on your specific property.

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.
