    • While it is Not Recommended to supply raw or filtered water to multiple "consumers" from a single inlet source (i.e.,: toilets, washdown pumps, air conditioners, generators, etc) it is recognized that it is common practice to do so, particularly when one or more of the consumers is an intermittent consumer.
    • If this is your intention, protect your equipment by installing a GROCO RWM Raw Water Manifold
    • You will be guided to use proper pipe or hose sizes, thus reducing the possibility of imposing dangerous restructions to one or all of the consumers
    • The barbed outlet is connected to the primary consumer (your main engine, for example), and is smaller than the threaded inlet which screws into a seacock or strainer outlet of the next larger pipe size (see sample installations)
    • The larger threaded end requires that a larger strainer or inlet seacock be used, thus assuring adequate flow to all consumers
    • The combined cross-sections of the primary consumer plus the threaded secondary consumer connections (to A/C and generator, for example) does not exceed the cross-section of the threaded inlet end
