High bacteria counts
1. Thimble is stained or dirty
2. Feed water quality changed
3. Contamination in water
after UV system
4. Possible break-through of
sediment through pre-filter
1. Clean the Quartz Sleeve
2. Have raw water tested to ensure that water quality is
still within bounds
3. It is imperative that effluent water stream be treated
with HydroSil Ultra before water leaves UV system-
disinfection system must have a bacterial free
distribution system to work effectively
4. Have source water test for turbidity-use cartridges
with higher filtration precision
Water appears milky
1. Caused by air in the water
lines
1. Run water till air is purged
Moisture inside the
Quartz Sleeve
1. Quartz Sleeve is broken,
cracked or O-ring not properly
sealed.
1. Visually inspect the Quartz Sleeve. If broken or
cracked, replace thimble. Re-install the Thimble if the
O-rings are not properly seated.
System shutting down
intermittently
1. Interrupted power supply
1. Ensure system has installed on its own circuit, as
other equipment may be drawing power away from UV
(ie. pump or fridge)
2. UV system should not be installed on a circuit which is
incorporated into a light switch
