Family-Owned Irrigation & Plumbing Company

Whether you are a homeowner or a business owner in Eastern CT, maintaining proper irrigation is vital to ensure your lawn remains lush and green. Achieving a balance between water conservation and providing enough water for healthy plant growth is key when it comes to high-quality irrigation and sprinkler systems. Insufficient water can lead to a patchy brown eyesore, while excessive watering not only wastes water and money but can also harm your greenery by drowning it.

At Maxum Irrigation & Plumbing, we believe that beautiful properties begin with a healthy, green, and thriving lawn that are well plumbed.

My 1st experience with Maxum was a winter shutdown in August on short notice to prep for property excavation notice. Maxum was very responsive and prompt. Jason D. was very courteous and professional. I will certainly be using them going forward.

Great Job today by Scott. He found two heads that needed adjusting to give me more effective coverage. He also check with me to do a walk around. Good job and great service

Karen Scopino

Maxum employee Scott did an excellent job explaining and addressing our questions and he carefully checked the operation of each sprinkler head.

Dave Mayhan

We had an issue where our grass was dying because the sprinkler heads weren’t popping up at all, just 3 weeks after Maxum turned the system on for the season. GREAT experience with the technical JASON D. who showed up to diagnose and fix the problem immediately, due to a completely solidly clogged filter full of slime and muck. However, I wish this was caught by the initial technician who serviced the system, saying everything was working fine…when none of the heads were even getting enough pressure to pop up. In recognition of this, Maxum did not charge for the service visit, and that integrity was much appreciated.

Maxim installed a new lawn sprinkler system last year. Excellent experience with the install and service. Especially like that their system included so-do connected controls that help manage the amount of water put on the lawn. A real money saver.

Daniel Price

Had Maximum replace my two outside faucets, and install shut off valves inside. Kevin came the next day- was incredibly professional ( he was the one who suggested the shut off valves) and fast. Did a great job. I would HIGHLY recommend these guys for any plumbing job - interior or exterior.

Just had Maxum install inground irrigation at our house. From the initial consultation, to the plumbing and install - everything went perfect. Their communication throughout the process was great; explanation of the system & what's entailed during install - timeline of install & lastly, how to use the system. The crew worked 2.5 days installing 16 zones in some of the hottest days of the year. They were extremely professional & knowledgeable. During the install we quickly found out I grow rocks better than grass... the crew was very thorough in cleaning up the rocks and minimizing the damage to the lawn while they installed each zone. I am very impressed by the final product & would definitely recommend Maxum to anyone looking for inground irrigation. Thank you & kudos to a job well done!

My lawn irrigation system was installed by Maxum 14 years ago. Since then they have maintained the system impeccably. The staff is knowledgeable and pleasant. I enthusiastically recommend them .

James Ouellet

Last Fall we called Katie and scheduled Maxum to come in and review our watering needs and design a system to handle our homes complex layout. From the consultation and design with Bob to the install with Kevin, Brian and their team, everything was extremely professional. Jordan and Kevin returned this Spring to Launch the "Start-up" of Our 48 head, 15 zone system, and we couldn't be happier. Maxum was absolutely professional throughout the entire process. If you are leading a busy Life and are looking to beautify your Lawn and Gardens, I would highly recommend you calling Maxum for a review. We just bought back our "Time Freedom" by not having to worry about the chore of watering our property. Thank you to everyone at The Maxum team..
