At E. Garrity Water Solutions we focus on quality water improvements over quantity. We use our years of experience and expertise to complete your project with perfection. Customer service and honesty are the most important aspects of our business, and your satisfaction is guaranteed. Please call us today for an estimate. We look forward to working with you.

"For weeks, we were getting less and less water from our faucets. Finally, we were down to a dispiriting trickle. A first visit from Garrity did not resolve the issue. When, concerned, I called back several days later, they immediately dispatched Joe and Cody, who arrived w/n 15 min. They probed deeply to find out the cause, discovering a cracked pipe and failing well pump, dating from about 30 years ago. They installed a new pump and new well cap up to current code and ensured that the water coming from the well was bacteria-free. This am, Joe was back by 8 am to show us how to flush all chlorine residues from our system and explain what he had done. Joe was determined, undaunted and kept at it until he found the cause of the inadequate water pressure--despite the late evening hour yesterday. His explanations were informative, clear every step of the way and helped us understand what was going on. He was patient, amiable and very good at what he does. Thank you Joe, Cody and Garrity!"

Septic tank services FAQs

Yes, most states require septic tank installers to have a license, and for good reason. Hiring an unlicensed septic tank professional could lead to poor quality work, added future expenses, and potential code violations. A licensed septic tank installer tackling your projects only protects you as a homeowner. 

As you browse our pro listings, take note of the “Angi Certified” badge. Angi Certified businesses meet our standards for certification which include:

  • The owner, principal, or relevant manager passed a criminal background check

  • Required to have applicable state and local licenses

  • Maintain an average star rating of 3.0 or better on our network, if they have at least one review

  • Paying to advertise their services

  • Meeting any other eligibility criteria required by Angi

The cost to replace a septic tank is $7,350 for the average homeowner. This cost can range, however, from $470 to $22,500, depending on several factors. Your house size is a significant factor in the overall cost, but other things like material type impact the final price tag. For example, installing a new septic tank in a one-bedroom house typically costs $500 to $900, whereas installing a new septic tank in a five or six-bedroom home is generally $1,200 to $1,600.

The cost of septic tank repair is $1,775 for the average homeowner. However, depending on a few elements, you might pay as little as $170 or as much as $6,100. Location, repair type, and tank material all determine the final cost. For example, replacing the septic tank filter can be as little as $200 to $300. However, repairing septic lines costs more, averaging around $1,500.

A septic tank can typically last 15 to 20 years on average, though your system's lifespan will vary depending on the type of septic system and the materials used. To help increase your septic tank's lifespan, schedule routine maintenance and do not flush items like cat litter, cigarette butts, or paper towels.

Repairing or replacing a septic tank is a job best left to a professional. Your septic tank is an essential part of your home, and if installed or repaired incorrectly, it could lead to significant problems. Things like polluted water, property damage, and health risks to your family could all happen as a result of an improper septic tank repair or installation.
