• Why does my Chapin pump not run continuously?

  Many Chapin sprayers use on-demand pumps (like the 12V diaphragm pump). The pump only runs when there is flow demand, such as when the spray wand is open or if there is a leak in the system.

• How do I clean my sprayer tank after use?

  Rinse the tank thoroughly with water only, empty it, and refill with clean water. Spray for at least one minute to rinse out the lines and nozzle. Store the sprayer upside down in a warm, dry location.

• What should I do if my pump will not prime?

  Check for debris in the strainer or kinks in the inlet/outlet tubes. You may need to prime the pump by creating suction (e.g., using a garden hose to flood the intake while the pump is running) or ensuring the inlet valves are clear of debris.

• How do I register my Chapin product for warranty?

  You can register your sprayer or spreader online at the official Chapin Manufacturing website under the Product Registration & Warranty section.

• Can I use powder-based chemicals in my sprayer?

  Yes, but ensure the powder is thoroughly dissolved in liquid before adding it to the tank. Powder-based chemicals can be abrasive, so thorough cleaning after use is essential to extend the life of the sprayer parts.
