I`m trying to make a puzzle game where the player is presented with a grid of pipes with one water source. The player has to rotate the pipes in order to connect them all to each other and, of course, to the water source.

The problem I`m stuck with is this:

Step 1:

Step 2:

Step 3:

As shown in the pictures, when I rotate a pipe that is connected to a group of other pipes, the connection to the water isn`t broken in the remaining group, it only works in a single adjacent pipe.

This is happening because of the way I`m doing the connections using a group of colliders in each exit of the pipes, as shown in the pictures below.

Colliders - Scene:

Colliders - Hierarchy:

If the collided object is connected to water (by a bool), it adds the collided object to a list. If the list is greater than 0, activates the blue sprite. If the list is empty, deactivates the blue sprite. As shown in the code sample below.

Triggers that check if the object is connected to water:
