Check Valves
Check valves will not operate satisfactorily if
deposits form on seats or if seats become damaged.
Hot water or steam entering cold supply or vice versa
indicates service is necessary.
To service check valves, first isolate supplies.
Remove cap (196 08). Clean seat using a proprietary
scale solvent. Slight damage to seats can usually be
lapped out, otherwise check valve must be replaced.
Examine clack facing (195 08 or 195 11) and if
damaged replace. When replacing clack facings
ensure facing screw (610 91) is firmly tightened.
Check cap gasket (634 33) is in good condition.
Should you experience a problem not covered by
these instructions, our advice should be sought.
