"Luis Septic Service agreed to replace our septic ejection pump and tank alarm with the pump and alarm switch I had purchased. As we tested together we agreed that the Alarm switch or circuitry was the reason the alarm had triggered and not because the tank had overflowed. I elected to replace the pump as the old one was 7 yrs old. We worked together and completed the project successfully ... $500"

"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."

"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."

"DEFINITELY RECOMMEND! Joe and Denise are very nice and easy to talk to. They listen to what you need and made sure you understand the plan before they do anything. We asked for extra work and are very accommodating. With regards to work itself, they took their time to do it right. With us, we had a last minute change of septic tank size and Joe was so nice to accomodate us. They did an excellent job with our septic system and will definitely recommend them. We also feel like we gain a friend!"

"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

If you aren’t sure if you have a septic tank or a cesspit, you can check your property records or inspect your drainage system. A septic tank has an outlet pipe that allows liquid to drain into a soakaway or drain field, while a cesspit is a sealed tank that requires frequent emptying. If you notice a manhole cover and no nearby drainage field, it’s likely a cesspit. Signs like slow drainage or a frequent need for pumping can also provide clues. A professional inspection is the easiest way to confirm if your home runs on a septic tank or cesspit.

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.

The easiest thing you can do to prolong the life of your septic system is to adopt septic-safe practices. This includes not flushing non-biodegradable items, chemicals, or excessive grease down drains and scheduling regular septic tank pumping to prevent buildup. It’s also important to fix plumbing leaks promptly and to practice water conservation to avoid overloading the system. To maintain your drain field, avoid heavy vehicle traffic and plant shallow-rooted vegetation in the area. Most importantly, invest in routine inspections and maintenance to detect and address issues early.

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.

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.
