Making Salt Work
"We DO in fact have products that are more salt friendly than others and would certainly mitigate rust in a salt pool environment. Products that we would promote for use in a salt pool environment include the following products:
Edge Diving System (NEW)
T7 Diving System
Sacrificial Zinc Anode (NEW)
Powder Coated Rail Goods
As always, we’d have to stress to customers that there is no guarantee against rust or corrosion in a salt pool environment. By taking steps to ensure proper pool water/salt chemistry, that any return jets are pointed away from any in-pool rail goods, and that any necessary product maintenance is performed, you can certainly help diminish the risk of rust.
The diving set up that you saw in our counter brochure is called the Edge Diving System™. [Ed. note: I had written and asked about that system in particular. You should take a look at it. It's a unique approach to keeping the salt from corroding the diving board base] It was specifically designed to replace all of the rusting steel Techni-Spring diving bases, and our competitor’s product equal, that are out in the field. The Edge Diving System is comprised of composite materials and fits the same 12” on center jig as the steel Techni-Spring base. I have attached both a photo of a rusty steel Techni-Spring base and an Edge Diving System for reference."
"Lastly, powder coated rails offer yet another layer of protection against rust and corrosion for pool rails. The layer of powder coat paint acts as a barrier between the elements and the stainless steel rail. One thing to mention is that if a powder coated pool rail is winterized and continually pulled in and out of the anchor sockets, the risk of paint chips and scratches increases which expands the risk of rust at those damaged paint areas. For optimum rail protection, a powder coated rail in conjunction with a sacrificial zinc anode is the best way to go."
I knew I was going to post again. I just didn't know when. I think it was a little bit like writer's block. I felt that there was nothing left to say about how bad salt was. But time has passed and the industry has reacted - mainly by caving in to the Salt Peddlers - and now there's lots of topics to discuss again. Just in time for the upcoming swimming season!
I've heard a lot said lately about the public driving the SWG market and builders finally conceding and trying to figure out how to cope.
Outdoor residential, 365 days a year in the sun, chlorine at 10 bucks a gallon? Ok sure, but an door public pool? Could never figure the math that goes into selling a $200,000.00 potential nightmare and stating its the cheap way to go. If that was a 3 pool system, heck that might cost upwards of 3-5k for the complete 3 pump liquid chlorine system. And silly me for thinking the cost savings on NOT spending 20k a year on cell replacement would cover freight on your liquid.
And I love going to a new/retro SWG pool and hearing all the proud patrons explain to me how they don't have any chlorine in their salt water pool.
If you wanna fight the good fight though, learn to love Ozone. I think SWG might have its place, but Ozone should be mandatory, at least on public pools. Unfortunately it gets done poorly too often.
Will be interesting to hear your take on the latest round of UV. Medium Pressure systems seem to be all the rage now. Time will tell but I still don't think it can hold a candle to Ozone.
You brought up a couple of my favorite topics; salt systems on commercial pools and salt systems on indoor commercial pools.
I wondered the same thing; how do you rationalize the huge pop for new cells every year as not a higher cost than buying chemicals for the same period of time?
Then, how do you mitigate the corrosion damage that the salt water is going to do to the structure that's housing your indoor pool?
I wrote a couple of blog pieces about that in june 07 and July 08 about a particularly disastrous application of salt to a wave pool in Canada. There's commentary on the eventual remodel from the facility manager as well. It's under the Indoor salt pool problems tab. Take a look.
I haven't taken a very hard look at ozone, to be honest with you. All of my business is residential and we're not dealing with swimmer loads so vast that we need supplemental devices like ozone for the most part, and I don't know enough about commercial applications to say much. But I'm interested to hear from you on the subject. E-mail me about it. I'll look over what you send me and try to put together a blog piece from it.
Thanks for reading and especially for writing.
