GENERAL REFERENCE PAGE
 
     
          The piping systems appropriate to this group are discussed under their own separate sub-group headings.  
 
For trim and drain systems see - S48-1
For fire mains and flooding systems see - S93
For fresh water systems see - S36
For scuppers and plumbing drains see - S48-8
For sounding tubes and vents see - S48-9
For fittings see - S48-23
For valves (general) see - S48-24
For Ship's horn see - S49
 
          It will be noted from the foregoing that certain sub-groups under S48 have not been used.  This is accounted for by either the absence of such systems, or by the fact that the components discussed are integral parts of other systems discussed under other "S" groups.
