Typically, engineers and product manufacturers who are worried about salt spray corrosion think of nearby oceans as the biggest contributor to this problem. And while that’s almost certainly the case in most situations, it’s worth pointing out that the recent trend toward salt water swimming pools has created another source of corrosion that is affecting everything from nearby buildings to consumer products.
Salt water pools are favored by consumers due to the fact that they require lower use of chlorine to keep them disinfected and clean. This means lower maintenance costs, as a homeowner won’t have to hire a professional pool maintenance company to scrub the sides of the pool on a frequent basis.
But according to a recent press release from Bionizer Pool Systems, a company that designs pool ionizing equipment, many homeowners are discovering that their salt water pools are contributing to corrosion of metal components and items that are nearby. This isn’t a good sign for those homeowners with these pools installed or those that plan to, especially if they’re keen on keeping their property maintained carefully should it ever come to the time of selling their home with a local realtor or using a platform like Reali or others online – as using either option will still call for a home inspection which will include the pool and surrounding areas.
“We’re finding that people prefer zero salt because their metal pool surrounds, like hand rails and outdoor furniture corrode, then they find their pool surface and even pool equipment deteriorating,” Ian Jones, Bionizer’s CEO, said in the press release. “Salt seems like the way to go at first, then customers get frustrated that they need to run their pump 12 hours a day just to generate enough chlorine for sanitization.”
As a result, some pool contractors are advising their customers to move away from salt water systems and instead favor alternatives that don’t rely on chemicals or salination.
For product manufacturers, particularly those who design pool products, the corrosion from salt water is something that should be anticipated when choosing materials. The best way to verify corrosion resistance is to employ the services of a environmental testing laboratory that has the equipment necessary to perform accelerated corrosion testing.
