VPS pH Down + Line Cleaner efficiently dissolves salt deposits and reduces biofilm accumulation within irrigation systems. This powerful cleaner, specially formulated to protect irrigation equipment, including seals and membranes, ensures maximum irrigation efficiency. Available in 1-gallon, 5-gallon, and 55-gallon drums to suit all operational needs.

Application Instructions:

• Use strictly between growing cycles (do not apply when plants are actively growing).

• Inject VPS pH Down + Line Cleaner into your irrigation system, aiming for an outgoing water pH of 2.0-3.0 at the drip emitters or hose bibs.

• For batching systems, prepare a water-acid solution at the same target pH.

• Operate the irrigation system with the prepared solution until pH reaches 2.0-3.0, then run for an additional 10-15 minutes.

• Immediately clean or replace system filters after acid treatment.

• Flush the system thoroughly with clean water in the following order: mainlines, distribution manifolds, drip lines, and drip irrigation flush valves. Continue flushing until water is clear and neutral in pH (typically 1-3 minutes).

For best results, follow up with an oxidizer to further enhance the cleanliness and performance of your irrigation system.
