TROUBLESHOOTING
Table 2 provides a troubleshooting guide for the DS05 Dial Pressure Regulating Valve.
Table 2. Troubleshooting the DS05 Dial-Set Pressure Regulating Valve.
Problem Solution
Whistling noise. • Slightly increase or decrease the outlet pressure until the noise goes away.
Will not hold pressure. • Clean the filter cartridge as described in the installation section.
Chatters. • Replace screen and O-rings.
• Replace the cartridge as shown in Figure 3.
Freezes up. • Replace bonnet or cartridge if damaged.
• To avoid further freeze up:
— Temporarily (slightly) open a downstream faucet if the DS05 will be exposed to
temperatures below 32° F (0° C). The slight water flow will eliminate freeze-up.
— Move the DS05 to a location with an ambient temperature above 32° F (0° C) if it is
currently exposed to prolonged temperature below 32° F (0° C).
Pressure gauge measures a lower
pressure under flow conditions than was
originally set during static conditions.
• DS05 is functioning properly. No action is necessary. The pressure decrease is
characteristic of all direct acting pressure regulating valves and is referred to as
falloff.
