Misting System Leaks
A misting system is a great idea for cooling down the air outside. These systems can cool the air by 20 degrees, but they do need occasional maintenance.
Most of the systems we see are purchased at the big box stores. These systems are all-in-one systems and you can add to them if you need to. They would be considered the lower end of the quality scale, as they don’t have many bells and whistles as custom systems do.
It is common to see the system dripping, particularly from the area of the nozzles. This doesn’t necessarily mean that there is a leak though. The pressurized water sprays out of the misting nozzles and as water sprays out, it collects on the nozzle itself. When enough water mist collects, it forms a droplet and falls to the ground. So you will see some small drops of water under each nozzle. I wouldn’t worry about it too much.
If the nozzle isn’t spraying at all, then you can worry. It is clogged up with mineral deposits and is blocking the nozzle from operating. You might be able to pick at it and get it spraying again, but most likely you will need to remove it and clean it out.
You can use a toothbrush and a mild vinegar/water mixture. Let the nozzle sit there for awhile and then brush the deposits away with the toothbrush.
