System Maintenance 

 
STANDING LIQUID 
If the system is equipped with a cast iron pump, liquid should not be allowed to sit in the pump 

discharge casing during the periods of non use.  Drain liquids by disconnecting the discharge hose 

from the pump outlet. 

 

Water Quality 

For maximum performance and reduced frequency of membrane cleaning cycles, remove or sequester 

calcium carbonate, ferrous iron, and calcium sulfate from the feed water via water softening or an anti-

scalant chemical feed system.  (Use test kit to check water quality.) 

 

Follow these basic guidelines to minimize unplanned downtime:  

 

Complete Log Sheets regularly.  Add data as needed. 

 

Review the data periodically.  Look for unusual readings and trends. 

 

Be familiar with your equipment.  Periodically inspect all components. 

 

Use sight, sound, smell and touch.  

• Look for leaks 

• Listen for unusual noises 

• Sniff for unusual odors 

• Touch for heat and vibration
