Routine Diving Board Maintenance

Routine Diving Board Maintenance

Disclaimer: This article is written to expose operators to some potentially new ideas about diving board safety.  Every situation and installation is unique and in no way is this information to be interpreted as a complete safety plan for your unique situation.    Diving boards are a fun and entertaining attraction at a pool.  Kids love them, athletes compete on them, and risk managers hate them.  Sadly, many of the 3-meter diving boards around the country have been "risk-managed" out of facilities.  Several aquatic consultants have presented data at trade shows that indicate that the risk involved with 3m boards was overstated and exaggerated,...

19 children sickened from pool chemical exposure - are you testing your flow switches and electrical interlocks?

19 children sickened from pool chemical exposure  - are you testing your flow switches and electrical interlocks?

On October 4, 2018, 19 children who visited a public swimming pool in California were reportedly sickened by the pool chemicals and 12 were taken to the hospital for treatment.  None of the injuries ended up being life threatening, but it could have easily been worse.  Pool chemicals were to blame, per the media anyway.  See one of the news stories here.   We were not involved in investigating this incident in any way, so this post if purely conjecture...BUT...whenever we see these types of stories, we discuss them internally and hypothesize what may have happened.  In this case, one possibility that...

CASE STUDY: Advanced Oxidation Process (AOP) using hydroxyl radicals for pool disinfection?

CASE STUDY:  Advanced Oxidation Process (AOP) using hydroxyl radicals for pool disinfection?

While touring the exhibit and vendor's hall at a recent aquatic management conference, we stumbled onto a product that we had heard of, seen installed at clients' pools, but had no direct experience working with.  Appearance-wise, it had a PLC control box/cabinet similar to a VFD or UV, a strange cylinder inside the cabinet, and some flexible poly tubing coming out.  Our brains went directly to ozone, but as we approached it became clear this was not ozone.  In talking with the rep he informed us that it was an AOP device...a device that created hydroxyl radical gas (a strong oxidizer and disinfectant) in...

Sacrificial Anodes in Swimming Pools

Sacrificial Anodes in Swimming Pools

  This picture shows several anodes from a medium pressure UV disinfection system installed on a swimming pool return line.  The anodes are in various conditions from brand new (top - #1) to completely disintegrated (bottom - #6) to illustrate how the sacrificial metal gets destroyed over time.  Ideally operators are checking and replacing anodes before you get to #4,5,6 above.  If we pulled an anode and it looked like #3, we'd change it out instead of return it.  #2 is debatable maybe - it would depending on how big of a job it was to get the anode removed.     More...

To Stabilize or Not?

To Stabilize or Not?

  To stabilize or not?  We get this question all the time from clients!  Here are a couple facts and recommendations when using stabilizer in your pool. In a pool environment, "stabilizer" is the same thing as "conditioner" is the same thing as "cyanuric acid".  Different words for the same product.   Stabilizer is 99.9% of the time an OPTIONAL product.  You do not have to add this product to your pool.  It does not help balance your water in any way, and it does not help your sanitizer (chlorine) work any better.  Completely optional.   Stabilizer does not come into your...
