The spray ring assembly provides a more consistent means of mixing the salt and water to
meet the brine saturation requirement. The spray ring at the top of the tank eliminates
possibility of channeling (or short circuiting) the water through the outlet of the tank. Adding
a quartz rock bed at the bottom the tank also reduces the possibility of brine channeling for
any application. Figure 17 provides an illustration of the spray ring assembly installed in a
quartz rock bed (left) and tank assembly without quartz rock.
Figure 17 Internal View Float Valve Assembly and Detail
For instances where the float needs to be removed, turn off the water to the system.
Remove the (red) cap on top of the stillwell. Unscrew the 3/8” PVC coupler that mates to the
feed water line and the black threaded flange connection protruding through the tank wall.
Unscrew the coupler that mates to the plastic spray ring. The float valve can now be pulled
out the stillwell. The float itself, can be unscrewed at the clevis hinge that mates with the
open/close poppet valve. To re-install the valve assembly, repeat step in reverse order,
making sure to use Teflon tape for replacing all NPT connections. Replace red cap and return
water supply. Verify float does close once high level is reached and system is not flowing
water.
