[Public-list] Original gatevalve sizes

[Jack Vanderloo]

Has anyone gone through a recent gate-valve to ball-valve/seacock 
conversion, i.e., from the original gate-valves on a liner-vintage A30 
(1977, 1978)?

My boat is about 500km/300mi from home, so I'd like to document the 
existing arrangement for planning/costing purposes while the water is 
still hard.

Aside from the engine discharge, what are the nominal sizes of the 
following original GATE-valves:
Cockpit/deck drains
Engine cooling intake
Sink intake
Sink discharge
Heads intake
Heads overboard discharge

Thanks

Jack
