10. The 4 way valve used in Perfecto Series Concentrators does have an acceptable tolerance of leakage per RexRoth By nature of the valve design it is possible for the valve to experience small leaks and still operate without affecting the overall performance of the unit The valve is assembled where the components that make up the valve Snap together The only screws in the valve are for securing the valve to the manifold assembly According to RexRoth there is an acceptable leak specification of 60 cc per minute at 137 89 kPa 20 p s i on each valve Valves that have leaks within this specification will function properly without any adverse effects to the performance of the concentrator A leak in the amount of 60 cc or less would be indicative of the type of small leak you would notice where the end caps connect to the main body or where the three pieces of the main body connect together A 60 cc leak would not be noticeable when examining the system pressure swings Leaks greater than 60 cc are indicative of cracks in the end caps or a blown seal where the end cap connects to the main body of the valve These leaks are detected by either reading the system swing pressures noticing two consecutive swings not being equal or by hearing an audible leak every other cycle Leaks of this extreme nature indicate the valve needs to be replaced Valves should only need to be replaced when the following conditions exist 1 A visible
