Special Situations
Supplemental Heat
Immersion heaters are available for cold weather climates. The 250-watt heater part #16311 should be adequate
for Thrifty Kings. Additionally, self-regulating heat cables are available to protect supply hose from freezing,
120V, part #16276. Immersion heaters should be placed flat on the bottom of the valve chamber. Ensure that the
placement of the heater and its power cable do not interfere with the motion of the float assembly.
Note
: Supply line heat cables should wrap around the valve, and follow the supply line down into the
riser tube. You may use nylon ties to anchor the heat cable to the supply line.
Non-Siphoning
The Ritchie Thrifty King fountains meet Grade-A dairy non-siphoning guidelines.
Ritchie Valves
Ritchie valves come in two sizes and four pressure ratings – blue for very high pressure, green for high supply
line pressure, red for moderate supply pressure, and white for low-pressure applications. Differences in the size of
trough also impacts valve choice. Although different pressure rated valves may be used in a fountain, each
fountain will only accommodate one size and configuration of valve.
The Thrifty King CT1-2000 uses the smaller 1/2"
valves
. A red valve is standard on the CT1 units. This
valve accommodates most common operating pressures,
and provides more than adequate water flow rates for the
number of animals that could be drinking at any one time
from these troughs.
The Thrifty King CT2-2000, CT4-2000 and CT6 use
our larger 3/4" valves
.
Green valves are standard on the
CT2-2000, CT4-2000 and CT6.
Alternate valves can be used for different water
conditions. If water pressure is over 60 psi, and if the
valve does not shut off, a pressure-reducing valve may
be needed.
Your individual situations may require a change from the standard valve supplied with your fountain, see your
Ritchie Dealer if this is needed.
