Fertigation Skid Pump and Probe

The fertigation skid check is the pump seal, the injector, the tank, and the pH reading the installed probe already shows. The technician writes the as-found reading and compares it with the last one on the asset. Do not change a nutrient concentration or a pH setpoint. Anything past that line belongs to the site's own procedure, the OEM manual, or a permit. This is the inspection ChatterFix schedules. It is not itself permission to go further.

The Procedure

The steps ChatterFix schedules for this PM. Every step is a checkable item on the work order — a technician can speak their way through it without touching a keyboard.

  1. With the pump stopped, inspect the seal, the injector and the tank for leaks
  2. Confirm the pH probe is the one the site installed and record the reading it shows
  3. Look at tubing for kinks and unlabeled lines
  4. Do not change a nutrient concentration or a pH setpoint from this work order
  5. A leak is isolated and written up

Why This PM Exists

The fertigation skid check is the pump seal, the injector, the tank, and the pH reading the installed probe already shows. The technician writes the as-found reading and compares it with the last one on the asset. Do not change a nutrient concentration or a pH setpoint. Anything past that line belongs to the site's own procedure, the OEM manual, or a permit. This is the inspection ChatterFix schedules. It is not itself permission to go further.

What Skipping It Looks Like

A drifting probe gets 'corrected' by moving the setpoint, and the leak at the injector waits. The round still closes, the number never lands on the asset, and the next person inherits a guess. Do not change a nutrient concentration or a pH setpoint.

Setting the interval

Every two weeks, pump stopped. A leak is isolated and written up. An as-found reading outside the limit the site already published is a finding. It does not become a new setpoint on this work order.

Common Questions

How often should this PM run?
Every 2 weeks. Every two weeks, pump stopped. A leak is isolated and written up. An as-found reading outside the limit the site already published is a finding. It does not become a new setpoint on this work order.
How long does it take?
Budget about 1.0 hour for a technician working to the standard procedure. ChatterFix uses that estimate for capacity planning, then learns your plant's actual time from completed work orders.
What happens if we skip it?
A drifting probe gets 'corrected' by moving the setpoint, and the leak at the injector waits. The round still closes, the number never lands on the asset, and the next person inherits a guess. Do not change a nutrient concentration or a pH setpoint.
