  • How often should I pump my septic tank?

    Septic tanks should generally be pumped out every three to five years to maintain optimal performance and prevent costly backups or system damage. Regular maintenance helps remove sludge and buildup that can clog your drain field and reduce system efficiency. Staying on schedule can also reduce the risk of unexpected septic repair issues and extend the life of your system.

  • Do you handle septic permitting?

  • Do you offer financing?

    Septic repairs and installations can be a significant investment, which is why flexible planning is important when choosing a septic service. Financing options can help homeowners manage costs while still addressing essential work without unnecessary delays. Whether you need a full system replacement, a new installation, or major repairs, financing solutions can make it easier to move forward while staying within your budget.

  • What should I do if my alarm is going off?

    If your septic alarm is going off, it’s important not to panic and not to tamper with the control panel or system components. The alarm is a warning that something isn’t working properly, such as a high water level, pump failure, or electrical issue, and attempting to reset or fix it yourself could make the problem worse. Instead, contact John C Cascio Septic Service Inc right away. Prompt professional attention from a qualified septic service helps restore system function safely and prevents further damage.

Do's and Don'ts of Your Septic System

Your septic system is a living organism. If a substance is harmful for you to ingest, it will also be toxic to your onsite system. 


  • Wipes (even if it says safe for septic tanks), condoms, or feminine hygiene products should not be flushed down the toilet. 
  • Toilet paper should come apart if shaken in a jar. 
  • Sinks/garbage disposals are not trash cans. Scraps, food waste, and oils should be discarded as solid waste. Ideally, anything traveling to the septic tank should first pass through your digestive system. 
  • Laundry should be done daily as needed. Waiting until the weekend to do multiple loads should be avoided. 
  • All cleaning products and detergents should say safe for septic tanks. 
  • Liquid fabric softener is inappropriate for septic tanks. It is an oily substance that is chemically designed to remain emulsified in water, no matter the temperature. As a result, it will travel through the liquid layer of the tank and out to the drain field. Once it leaves the tank, it will clog the infiltrative surface of the drain field, causing a premature failure. 
  • Your septic tank should be pumped every 2-3 years or when recommended by a professional/maintenance entity.
  • Additive use is not necessary. If an additive is used, it must be on the state-approved list. Refer to a professional for questions or clarifications. 
  • If a member of the household is taking chemotherapy, on long-term antibiotic therapy, or the recipient of an organ transplant, let your professional or maintenance entity know immediately. 
  • Any plumbing leaks should be fixed immediately. The water source should be turned off when the leaking fixture is not in use until the leak is repaired. 
  • If you are on a private source of water or well, it may be necessary to install a water meter to retain your warranty. 
  • If you have an audio-visual alarm, let your professional know immediately if the alarm goes off. Resetting, silencing, or unplugging any component will only make the situation worse. 
  • If you have an aerobic treatment unit (ATU), let your maintenance entity know immediately if there are any alarms. A technician will service your system semiannually or quarterly and report any issues to both you and the local health department as required by F.A.C. 62-6. 
  • If you have a water treatment system of any kind, the purge cycle must be discarded in a way that it does not discharge into the internal plumbing for the home.
