    If i could give more than 5 stars, I would. Place is great. It’s a real pool store with all of the things you need to maintain and repair your pool. They are extremely knowledgeable and friendly - just helpful. Everyone is always running around to help customers. They are all about service. I drive out from Plainview because they are that good. They have a loaner program so you can test robotic pool cleaners. Their service rates to diagnose and or fix problems on pumps, robots etc is totally reasonable. Worth the trip! Thank you Trevor and Charlie.

    Went here after getting a new in ground pool. Had the water tested here they give me a print out on exactly how and what to add and when. They sold me the exact chemicals I needed only they didn’t try to sell me any extra. Went back a week later I didn’t mention it was just to make sure everything was good after putting the chemicals they told me to put it. Water was perfect which I saw on the print out. Very happy to have this place local to me. Nice and easy and good advice ! Thank you for the help. Purchase a robot vacuum here also which was a nice and smooth process.

    Finally an honest and knowledgeable pool place! Testing is accurate and, unlike IR and Leslie’s, their recommendations are spot on (they don’t tell you to use double what’s needed so you’ll have to add other stuff to compensate). And can’t beat their recommendations for bigger equipment like the Dolphin Robots and salt systems
