Tips, Tricks, and Tools for every POOL Operator

Image
Starting out in this business having a mentor can be the difference between early on success and “learning the hard way” and for that reason I have compiled some useful tips and words of advice to help guide you. Know your worth by always charging for your time - The day you start handing out free services is the day you become “that guy”. That guy is the guy that people know they can call to troubleshoot an issue or come look at something that they will try fixing themselves and you have just lost yourself valuable time and money. Your time is valuable!! I think about “The Ship Repair Man Story” where the man fixes an engine issue others have failed to fix. He is studying the engine and then pulls out a hammer and taps this one spot and its fixed. It is less about the tapping of the hammer and more about the experience and knowledge it took to know where to tap. Value your work and charge accordingly. Each one, Reach one, Each one, Teach one – Don’t hoard information. We should alwa...

Key Court Cases Making a Splash

  Recent Legal Waves in the Aquatic Industry The aquatic industry—encompassing public pools, waterparks, splash pads and more—has seen a surge of high-profile litigation in recent years. These cases not only spotlight operator liability and public health concerns but also establish precedents that ripple across the sector. Below, we explore four pivotal lawsuits reshaping aquatics law and risk management. 1. Seneca Lake Park Spray Park Cryptosporidium Outbreak In 2005, an outbreak of cryptosporidium at the Seneca Lake Park Spray Park in Geneva, New York, sickened thousands of visitors. Plaintiffs filed the industry’s first class-action lawsuit, totaling 2,538 claimants. They allege that inadequate filtration and supervision led to the widespread waterborne illness. Attorneys expect settlement talks to intensify once discovery concludes—this could set a new benchmark for operator responsibility and engineering standards in spray parks and interactive water features. 2.

Water Level and Why it's Important

Image
 Maintaining proper water levels in your pool is critical for proper operation! What can happen if this is not done properly? Glad you asked.... Improper skimming - What do I mean by this? Well, we all know that most codes dictate that 75% of the suction needs to come from the skimmer or surface of the water. Even if you're not going based off code it's pretty standard practice to have more suction come from the surface than the floor drains. Most if not all contaminants in your pool are going to reach the surface of the water before any other place. When the water level is too high the system is not going to function properly, and you will have debris hanging out on the surface of the water and with that you will see deposits also starting to form at that water line.   Improper filtration - For the water in your system to properly filter it has to flow at a particular rate and if it does not then it will not filter properly. When your water isn't properly filtering you w...
