Cleaning a Cartridge Filter
Open, clean, inspect, and reassemble a cartridge filter safely, then confirm stable circulation and record a comparable clean baseline.

Sand Filters
Follow a sand filter through its media, valve positions, filtration and backwash states, pressure trend, failure clues, and model-specific limits.
- ProcedureBLX-SOP-025 · v1.2
Backwashing a Sand Filter
Backwash a sand filter through the correct valve and discharge sequence, restore filtration, and leave behind a clean pressure baseline worth comparing.
- GuideBLX-EQP-007 · v1.2
Diatomaceous Earth Filters
See how D.E. grids or cartridges, precoat media, valve states, and pressure trends work together, including the clues left by bypass or a poor recharge.
- ProcedureBLX-SOP-026 · v1.2
Backwashing and Recharging a D.E. Filter
Backwash and recharge a D.E. filter without losing control of pressure, valve position, wastewater, dry media, or the model-specific recharge dose.
- Troubleshooting GuideBLX-DIA-002 · v1.2
High Filter Pressure
Start with the system's valid clean baseline, then separate gauge, pump speed, filter loading, valve, return, and service causes of high pressure.
- Troubleshooting GuideBLX-DIA-012 · v1.3
Filter Pressure Is Low, Zero, or Unstable
When filter pressure is low, zero, drifting, or pulsing, separate a bad gauge from flow, suction, pump, valve, air, and operating-state problems.
- GuideBLX-EQP-008 · v1.2
Gas Heaters and Heat Pumps
Identify gas heaters and electric heat pumps, check the exterior controls and flow they depend on, and recognize when qualified service must take over.
- Troubleshooting GuideBLX-DIA-013 · v1.2
Heater Does Not Heat or Shows an Error
A heater that stops, stays cold, or shows an error needs a disciplined exterior check, not improvised gas, electrical, combustion, or refrigeration work.
