Pipe lines in a water supply system must be of sufficient carrying capacity to maintain adequate pressure at the most
remote or highest fixture. Under the maximum probable fixture use, minimum adequate pressure is generally 8 to 15
lbs., but may be more, depending on the equipment being supplied.
Valve requires laminar flow, must be installed 5 diameters downstream from any obstructions like elbows, pumps etc.
Relatively high service pressures which can create high water velocities in pipe lines would allow use of smaller pipes
to satisfy fixture use. However, high velocities tend to cause whistling and humming. Reductions of pressure by the use
of a pressure reducing valve, in an attempt to eliminate the undesirable condition, may reduce pipe line capacities below
what is adequate for maximum probable use.
When high service pressures are in effect, either continuously or periodically, the application of a pressure reducing
valve will be successful only when the installed pipe line is of adequate size to satisfy the system demand at the lower
pressure. When actual water demands are unknown, the valve size should be no less than the existing pipe size.
PROBLEM
1. Pressure and fixture flow unsteady.
SOLUTION:
A. Pump my need to be serviced.
B. Alternate appliance usage to reduce over usage.
C. Increase pressure.
D. House service lines may at times be inadequate for the load. Size of some pipes may need to be increased.
PROBLEM
2. Pump continues to cycle on and off
SOLUTION:
A. Readjust pressure switch setting higher than the regulated set pressure.
B. Readjust the regulated pressure setting on the valve to the cut in pressure of the pressure switch setting. For example
40/60 switch set the valve at 40 psi
C. Replace sealing disc in valve.
D. Replace diaphragm in valve.
E. Recharge tank or replace.
PROBLEM
3. Valve appear to be noisy, hums, whistles or
chatters
SOLUTION:
A. Use a second valve to reduce the differential pressure to the original valve.
B. Replace the small washer and sealing disc.
C. Reset the air pressure in the tank to 6-10 psi below the cut in (pump on) pressure setting on the pressure switch.
D. Make sure there is at least 5 diameters of straight pipe upstream.

Installation Instructions
POSSIBLE CAUSE OR CAUSES
A. Low water supply pressure in main supply line caused
possibly by inadequate pump pressure.
B. Heavy periodic demands by appliances in the house.
POSSIBLE CAUSE OR CAUSES
A. Pressure switch may not be set correctly.
B. Valve regulated pressure is set to close to the shut off
pressure of the pressure switch.
C. Sealing disc in valve is wore or damaged.
D. Damaged or torn diaphragm in valve.
E. Water tank has become waterlogged.
POSSIBLE CAUSE OR CAUSES
A. High velocity of flow in pipelines causing vibration due to
excessive pressure drop across valve.
B. Chatter usually originates with worn small washer or
loosely installed disc.
C. Air pressure in tank is set too high.
