These are all the new PipeWorks items that I have found so far. I checked and have not seen any more undiscovered ones in the book, but I can't guarantee that this is everything.
The items, starting from the back, going right and then row by row: (EDIT: The item I missed is the one far right, it's at the end of the list)
- PipeWorks Valve
- PipeWorks Lamp
- PipeWorks Connector
- PipeWorks Flute
- PipeWorks Gear Box
- PipeWorks Pipe
- PipeWorks Twisted Pipe
- PipeWorks Table
- PipeWorks Planter
- EDIT: PipeWorks Water Tank
Some items have an animation when connected to other pipes (the Flute smokes, the Gear Box spins, the Lamp turns on) But I have not seen any use except decorative. The Planter is, as the name suggests, able to hold plants, as is the table able to hold items. Every item has a shiny version, ~~but I haven't gotten all of those yet~~ you can see them on the right.
EDIT: The last item I found together with the planter makes it seem like the pipes would be transporting water? But then there is the flute wich emits smoke so that doesn't make a lot of sense. I think these items are really just decorative.
Good luck fishing for all those! Keep in mind that you need magnets from Pipi to reel in these items.
