ABYC on Seacocks

[Tim]

Here is some applicable information from ABYC H-27 | Seacocks, Thru-Hull Connections, and Drain Plugs. Posted for posterity.

Seacock: A type of valve used to control intake or discharge of water th rough the hull. It is operated by a lever type handle usually operating through a 90? arc, giving a clear indication of whether it is open or shut."

If a flanged seacock is used, its flange shall be securely mounted to the hull.

A seacock shall be securely mounted so that the system will withstand a 500 pound static force applied for 30 seconds to the inboard end of its connecting fitting, at any point in its most vulnerable direction, without the system failing to perform as intended.
