WATER STORAGE AND DISTRIBUTION -ISOLATION HANDLE AND ISOLATION/DRAIN VALVE HANDLE
Purpose
The isolation handle and isolation/drain valve handle let you operate the isolation valve and the isolation/drain valve.
Physical Description
The isolation/drain valve handle and the isolation handle are similar. Each handle connects the valve with a control cable.
The isolation/drain valve handle has three positions, open, closed, and drain. The isolation handle has two positions, open and closed.
Each handle attaches with two bolts.
Location
The isolation/drain handle is behind a panel above the passenger/entry door 2 left. The isolation handle is behind a panel above the passenger entry door 4 left.
Functional Description
When you turn the isolation handle clockwise, the isolation valve closes. This isolates the overhead distribution line. When you turn the handle counterclockwise, the valve opens.
When you turn the isolation/drain valve handle clockwise to the closed position, the isolation/drain valve closes. This isolates the overhead distribution line.
Operation
You turn the isolation and isolation/drain valve handles clockwise to move them to the isolation position. You must pull the isolation/drain valve and turn it to move it to the drain position.
Training Information Point
If the panel for the isolation valve is closed, the valve is in the open position.

WATER STORAGE AND DISTRIBUTION -INTRODUCTION -LAVATORY
Purpose
The part of the water storage and distribution system that is in the lavatory does these functions:
*
Lets you control the flow of water into the lavatory
*
Distributes water to components in the lavatory
*
Lets you drain water from the lavatory.
Physical Description
A typical lavatory has these water storage and distribution system components:
*
Lavatory water supply shutoff valve
*
Distribution lines and fittings (not shown)
*
Drain valve
*
Faucet (drinking fountain)
*
Filter
*
Faucet.
The system has interfaces with the water heating system and the vacuum waste system.
See the water heating section or more information on water heating (SECTION 38-13).
See the vacuum waste system section for more information on the vacuum waste system (SECTION 38-32).
