"Joe called ahead and was on time. He did an inspection of the system since we recently purchased the home and don’t know anything about septic systems. He thoroughly explained the system and didn’t try to recommend any services that weren’t needed."

"My husband and I just moved from Long Beach. We bought our house, and have never owned a house with a cesspool. I contacted Priority to come over to inspect the system and educate me about how to maintain it properly.
I called on a Friday morning, and they scheduled me for the next day. They called before they came over, within the two hour window of time that they had told me the day before. Paul was the knowledgable technician that came over to do the job. He located my overflow tank first and dug up the covering so we could look inside. Luckily, the overflow was relatively new and empty, so he closed it back up, and proceeded to dig up the main cesspool. The main cesspool was 75% full, but again in good shape. While he was working on the second cesspool, the owner, John arrived to introduce himself and to check out the system. Paul then suggested that we pump the cesspool and clean it, and gave me the quote before-hand so that I could chose what I wanted to do. I opted to get it pumped and cleaned.
While doing the job, Paul explained everything that he was doing, and took a lot of time to answer all of my questions( and I did have a lot of them). He always told me how much a service would be ahead of time so their were no surprises. The total time for the job was 2 hours. I will absolutely use this company again, and I would definitely refer them to a friend! Thanks so much for all of your help Priority!

"AAA was out of the gate before anyone else --- called me promptly and sent someone out to service my cesspool backup first thing in the morning--before any of the other recommended companies on Angi even called to schedule an appointment. Jeff showed up and quickly diagnosed my problem and solved it within 45 minutes. He knows his stuff and is willing to explain the situation clearly to us septic system civilians. Bravo to AAA and Bravo to Jeff!"

"I called cesspool Kings 24 hours emergency service number one day when my cesspool was clogged and water was backing up in my basement. I had no idea what was going on. I spoke to the owner of the company John. he was very knowledgeable and eager to help. He was at my house within a very reasonable time. After assessing the issue and going over the options with me. Himself andhis team were able to completely fix the issue and get my home back up and running like it was for years prior. I would highly recommend using cesspool Kings !!! and I will be a return customer. if I have any issues, moving forward with my home, they will be my first call Thanks again for all your help"

"Review for Cesspool Services I recently had the pleasure of working with Cesspool R Us for our property’s cesspool maintenance, and I couldn’t be more pleased with the experience. From start to finish, the team demonstrated professionalism, expertise, and attention to detail that made the entire process smooth and stress-free. The technicians arrived promptly, fully equipped, and ready to get to work. They took the time to explain the process clearly and answered all of my questions, which was greatly appreciated. The work was done efficiently, and they ensured that the area was left clean and tidy, going above and beyond in their commitment to customer satisfaction. What really stood out was their knowledge and thorough approach. They identified and addressed potential issues I wasn’t even aware of, which saved us from potential future problems. It’s rare to find a company so dedicated to quality service and customer care. I highly recommend Cesspool R Us for anyone in need of reliable, high-quality cesspool services. Their team is skilled, respectful, and truly dedicated to doing the job right. Thank you for providing such excellent service!"

FAQs for septic system repair projects in Central Islip, NY

Leach field failure can often occur due to a lack of proper maintenance, hydraulic overload, or environmental factors. When too much water enters the septic system—like running multiple large laundry loads back-to-back—it can overwhelm the leach field. Regular professional inspections, ongoing maintenance, and spacing out high-water-use activities help prevent failure.

A septic tank shows repair needs when noticeable symptoms arise around your home. Noticeable signs include strong sewage odors at fixtures, recurring pipe blockages, pooling water or damp patches near the leach field, and areas of unusually bright green or spongy grass. These indicators confirm that deteriorating components or clogs exist. Monitoring such signs and scheduling timely professional inspections prevents further costly damage.

Adhering to a strict, scheduled maintenance plan prevents septic system repairs. An annual inspection and a pump-out every three to five years safeguard your system’s performance. Additionally, only flushing waste and toilet paper, installing drain filters, keeping nonapproved items out of the system, and avoiding excessive water use help maintain your septic system’s health and efficiency.
