Table 4. Guide to Media Filter Performance
Symptoms	Cause	Solution
Poor filtration	Filtering media too thin	Add more media to the recommended level
	Wrong media	Add more media to the recommended level
	High pressure differential forcing contaminants through the filter	Exchange for correct media
Poor filtration with cone forming in the middle of the sand layer	Too high flow rate	More frequent back flushing required
	Filtering media too thin	More filters required
	Insufficient backwashing	Add media to the recommended level
Constant high pressure differential	Filters sealed--not enough water for backwashing	Increase time of/or flow of backwashing
Constant high pressure differential	Filtering media to thin	Remove the cover, scrape top layer, flush tanks until clean
Media down stream (in irrigation system)	Too high flow	Add media to the recommended level
	Wrong media	Reduce flow rate
	Air in the tanks, disruption of sand	Exchange for correct media
		Install airbleeds, automatic or manual
