direction of water flow matches the design of the flow switch. Flow switch usually
have arrows pointing the direction of the flow but if not, it’s easy to understand.
The armature will be toward the water flow so when the flow comes, it moves to
the post.
REPLACEMENT:
On pressure switches, they are not directional. If the new switch did not come
with pipe thread, add either plumbers putty or Teflon tape on the threads to help
seal the connection. So simply tighten to snug. The connections on the switch
are also non polarity so wires can connect either way.
On flow switches: note the direction of the flow of water. The new switch must
follow the same flow. Remove the clips and hoses and switch with new.
