Ames Fire & Waterworks 5001SS Reduced Pressure Detector Assemblies - Manual (Page 4)

PROBLEM CAUSE SOLUTION
A. Assembly discharges from Fouled first check Disassemble and clean No. 1
differential relief valve during check valve
no flow condition. Fluctuating inlet pressure Control supply line water pressure
Outlet pressure higher than inlet Disassemble, clean #2 check valve
pressure & leak in No. 2 check valve & identify cause of back pressure
Leak through diaphragm Service relief valve (page 3)
Pressure relief valve does not close See problem D
B. Assembly discharges from Pressure relief valve does not close See problem D
differential relief valve during
a flow condition.
C. Differential pressure relief valve Differential pressure across No. 1 Repair shut-off valves
does not open during test check valve stays above 2.0 PSI
due to leaking outlet gate valve
Weak or broken relief valve spring
Disassemble and replace relief valve spring
Winged retainer bound in body Disassemble and repair
Plugged hydraulic hose Disassemble and repair
D. Pressure relief valve Debris on sealing surface Remove relief valve and clean
does not close
Plugged hydraulic hose Disassemble and clean
Damaged seat or rubber shut off disc Remove relief valve assembly and replace
Ruptured diaphragm Disassemble and replace diaphragm
TROUBLE SHOOTING GUIDE - 4001SS and 5001SS
1. When using differential pressure gauge.
A. Check differential across No. 1 check valve
READING PROBLEM
2 to 3 PSID Leak in No. 1 or No. 2
check valve
4 to 7 PSID and steady Malfunctioning pressure
relief valve
2 to 7 PSID fluctuating Inlet pressure fluctuating
2. Without using differential pressure gauge.
A. Close gate valve No. 2
RESULT PROBLEM
If discharge stops Leak in No. 2 check valve
If discharge does not stop Go to B
B. Open No. 4 test cock to produce a flow greater
than differential relief valve discharge
RESULT PROBLEM
If discharge stops Leak in No. 1 check valve
If discharge does not stop Malfunctioning pressure
relief valve
