One of the most frequent issues encountered is a clogged or blocked nozzle. Over time, debris, dirt, or even dried liquid can accumulate, preventing the proper flow of liquid.
Signs of a Blocked Nozzle:
- Weak or no spray output.
- Uneven spraying pattern.
2. Low Fluid Level
If your reservoir doesn’t have enough fluid, the pump won’t operate effectively. Low fluid levels can often lead to the pump sucking in air instead of liquid.
Signs of Low Fluid Level:
- No mist is produced.
- Frequent air bubbles in the liquid.
3. Worn or Damaged Seals
Over time, seals in the pump may wear out or crack, leading to leaks. A sealed unit is essential for maintaining pressure; without it, your pump won’t function correctly.
Signs of Worn Seals:
- Liquid pooling around the base of the pump.
- Difficulty building pressure.
4. Air Leaks
Air leaks can also lead to the loss of pressure in the system. Any cracks or breaks in the pump casing can introduce air into the system, disrupting the spray.
