"Matt, AJ, Scott, Vinnie, Charlie all did a terrific job. They installed a gas water heater, installed a shut off on the water heater where there was one missing, replaced a kitchen sink from an old double sink to a new full size sink and in doing so, moved the garbage disposal and re-piped the whole project. They checked other pipes & plumbing and repaired a broken outside water pipe. Tisha in the office was also wonderful - very accommodating, congenial and they are all very customer service oriented. Respectful, honest, and I would highly recommend this company to anyone."

"I hired them because they said they could pump my septic AND snake my drain. They did pump my tank very nicely, they were available when I needed them, and they were able to identify a problem immediately. However, what they meant by snaking the drain is that they could send another person out for an additional fee to snake the drain. I was also only quoted for the pumping and not the snaking so I ended up paying double what I thought I was going to pay. I also found out AFTER the first payment/job that they had a military discount so that was a little disappointing, but I am very grateful that it was applied to the second payment/job."

"I am only giving them 5 stars because this rating will not allow 10 stars. Wayne and his crew installed a new septic system in our new Warwick, RI home. Everyone was extremely professional and courteous. They answered questions along the way as they worked through the complicated permit process. All of the crew were super personable and responsive. They also helped me move dirt on a landscape project I was working on while they had the heavy equipment. Saved me a lot of shoveling."

"The septic tank had not been cleaned for over 10 years. Bill, from Flushaway Septic came within an hour and a half of my phone call. He explained what had to be done after opening up the septic tank and did the job promptly and neatly leaving the area perfectly clean. He charged $275 for a total pump out with lots of solid waste. He explained how to keep the tank clean and suggested a cleaning every 3 years. I highly recommend him to anyone needing this service."

"Paul was very knowledgeable about what needed to be done to replace my whole Septic System. The installation that was completed was amazing and flawless. Paul worked with the town to get the system in and approved. Paul answered every question in a timely matter. I did not have to worry about anything regarding this big project. I recommend Paul 200% and would share his information with all my family and friends. Paul is a master at his work and is priceless in this industry. You will not feel like a number or inconvenience with Paul. Give him a call and let your worries be out to rest with his work."

Septic Tanks FAQs, answered by experts

Septic tanks come in multiple shapes, sizes, and materials. However, they’re often round or rectangular in shape and made from concrete, fiberglass, or plastic. There’s a range of septic tank sizes, with the average model measuring 30 to 40 square feet and holding 1,000 to 1,500 gallons of waste.

A mound septic system, when properly maintained, can last between 20 and 25 years on average—though some last longer or malfunction sooner than that. The most important part of maintenance is getting an annual inspection of the vital parts of the system to ensure they’re in proper working order and not too backed up with sewage.

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.

If your well pump is running continuously (meaning without turning off or stopping), it's a sign that your well pump is starting to break down. The length of time your well pump should cycle is dependent on many factors, like the tank size, pressure setting, and even the amount of water in your well. Generally, your well pump should cycle, or go from running to not running every few minutes.

Pump the tank every 3-5 years, avoid flushing non-degradable items, and address leaks promptly to extend system life.
