How to Maintain a Misting System

Keep the nozzles clean

Nozzles are the smallest openings in the whole system, so they are the first place Arizona hard water leaves mineral deposits. A clogged or partly blocked nozzle sprays unevenly, drips, or stops fogging, which hurts cooling.

Cleaning is straightforward. Remove the affected nozzles and soak them in white vinegar to dissolve mineral scale, then rinse and reinstall. Doing a quick check at the start of the hot season, and again mid-summer if you run the system hard, keeps the fog fine and even.

• Soak clogged nozzles in white vinegar to dissolve scale
• Rinse thoroughly before reinstalling
• Check nozzles at the start of summer and again mid-season

Flush the lines and check for leaks

High-pressure lines carry water at 1000 PSI, so a loose fitting or a nicked line shows up as a spray or a drip. Once or twice a season, run the system and walk the line looking for leaks at the fittings and along the tubing.

Flushing the lines clears out sediment before it reaches the nozzles. The brass fittings in a quality setup kit hold pressure well, but they can still work loose over time, so snug any that weep and replace tubing that has been damaged.

Service the high-pressure pump

The pump is the heart of the system and needs the most attention. Most high-pressure misting pumps use oil, which should be checked and changed on schedule to keep the pump running smoothly and quietly.

Listen for changes in how the pump sounds and watch that it builds full pressure. A pump that struggles to reach 1000 PSI, cycles oddly, or runs loud is telling you it needs service. Mobile Misting AZ services pumps across the Phoenix metro if you would rather leave it to us.

• Check and change the pump oil on schedule
• Confirm the pump builds and holds full pressure
• Call for service if the pump runs loud or loses pressure

Winterize before the cold

Phoenix winters are mild, but overnight lows in the outlying valley towns can dip near freezing. Water left in the pump and lines can freeze, expand, and crack fittings or damage the pump.

Before the first cold nights, shut the system down for the season, drain the water from the pump and lines, and store or protect the pump per its instructions. It is a small step that prevents an expensive spring surprise.

Consider a filter and local service

Because Arizona water is hard, an inline water filter reduces the sediment and scale that reach your nozzles, cutting down how often you have to clean them. It is an easy add that pays off in less upkeep.
