Water purification system for intended use in a dialysis setting has fittings that are made of brass.The brass fittings corrode and leak water.The leakage cause the membranes to lose their prime and system automatic flushing does not get initiated due to the pressure drop.The membranes and the water purification system due to not being flushed automatically stimulate bacterial growth, which becomes high and in an unacceptable numbers.There is potential that this will cause pts infections and pyrogenic reactions.The tests are performed on the purified water using bacterial colony counts in produced water for dialysis and lal (an assay that is used to estimate endotoxins in water) both tests giving numbers that are not acceptable for the product water.Fda safety report id# (b)(4).
