"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."

"Great experience Justin, Nate & Timothy were awesome. Very knowledgeable, professional & curious. Aside from the cleanliness they delivered an experience. I highly recommend HL bowman if you want rapid service on your HVAC. Pricing was reasonable in my opinion & financing is an option. Keep in mind when seeking quotes for your HVAC repair/ new install you must consider performance over equipment, that is if your want a good system that will have a good run/life span."

"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!"

Septic Tanks FAQs, answered by experts

While dry wells can be effective for managing rainwater, they have several disadvantages. They can become clogged with sediment, especially after large storms, which reduces their effectiveness and can be difficult to clean. Dry wells are also not suitable for all soil types; they will not function properly in soil with low permeability. Additionally, if a dry well is not large enough to handle the amount of rainfall in your area, it can overflow. For gravity-flow models, the water may disperse very slowly, depending on the well's depth and the soil's permeability.

The best way to keep a septic tank clean is to hire a local septic tank cleaner to inspect and pump the septic tank every three to five years. Be sure to only flush human waste and toilet paper down the toilet, and don’t pour grease, oil, fats, coffee grounds, or food scraps into your drains.

You can cover a septic tank riser with dirt, but it’s not always the best idea. If you have a plastic riser and you bury it, you can easily lose track of it since you won’t be able to find it with a metal detector. Make sure to clearly note where your rise is in your yard so that you’re able to access it easily the next time you or a septic pro needs it. Don’t bury the cover too deep or you could place too much stress on it and make it too difficult to access in the future.

A shallow-well pump can pull water up to 25 feet deep. A deep-well pump can pull water up to 90 feet deep. A deep-well submersible pump can pull water up to 300 feet deep. Make sure to consult a pro to find out how deep your well is and get the right pump for your needs.

With regular servicing and general upkeep, both a well pump and pressure tank can last for years. The average lifespan of a well pump is around eight to 15 years. A well pressure tank can last from seven to 10 years. How long a well pump and pressure tank lasts also depends on a variety of factors such as type, size, material, and brand.
