The safe A is cast with a slight pitch of the bottom to the pipe a, and with sides and ends of about one inch in depth. This is Figure 56. made sufficiently large to go under the heater and the connections which contain the valves, so that all joints that can possibly leak--unless those in the connections between the risers and valves--are protected, the drip from them, if any, falling into the safe.
