But indoor swimming pools have corrosive air pollutants, like chloramine vapor and trihalomethanes. Corrosion to stainless steel normally occurs when chlorine or chlorides are present, and nitrogen trichloride (aka trichloramine, NCl3) definitely fits that bill.
What pool chemicals are corrosive?
Chlorine is corrosive to metals such as steel and copper. Instances have been reported where exposed water piping has become corroded causing leaks, and also where metal storage shelves have corroded and collapsed, leading to chemical spillage.

Calcium Hypochlorite, aka pool shock or granular chlorine also has a long shelf life, if kept in an air tight container, in a cool and dry (indoor) location. … Properly stored, pool shock has a shelf life of over 5 years.
Will pool water corrode stainless steel?
Chlorine and a hot, humid environment make indoor swimming pools a very corrosive environment for metals and materials, particular- ly near ceiling level. Stainless steel has a long and successful history in swimming pool environments and has a lower corrosion rate than other metals.
Is pool water corrosive?
The aggressive environment of indoor swimming pools has a lot to do with the chemicals added to the water. Treating the water with too much chlorine will increase the risk of corrosion of the inventory inside the pool room and the swimming pool’s technical room.
How do you prevent chlorine from corroding?
Most corrosion problems can be avoided through proper stainless steel and finish specification, control of the pool environment, and maintenance cleaning. Cleaning procedures as simple as hosing or wiping down surfaces with fresh water are effective in removing chloride contaminates and preventing corrosion.
What happens if you put too much chlorine in a pool?
Having too much chlorine in your pool water can be dangerous. Exposure to high levels of chlorine can cause lung irritation, skin and eye damage, and provoke asthma. … High chlorine levels decrease the pH of your pool’s water, making it more acidic. The more acidic the water, the higher the likelihood of corrosion.
What does too much chlorine in the pool look like?
Excess chlorine can alter the pH level of the water in the pool, making it more acidic. The acid levels can cause any of the following symptoms: Irritant dermatitis which is a red skin rash characterized by raised itchy red bumps. Eye irritation and over-dilated blood vessels in the eyes.
How do I get rid of metal in my pool?

Is salt water pool more corrosive than chlorine?
Myth: saltwater pools have less chloramine problems. Again, it’s still chlorine, and chloramines will still be created. … Corrosion actually is worse for salt pools for at least two reasons.
Where is the best place to store pool chemicals?
Pool chemicals should be stored in a cool, dry, well-ventilated place. Garages are generally not the best place to store pool chemicals unless they are locked in a storage bin or cabinet.
