Trying to summon this bugged out and one the pipes wouldn't activate.

Contained in Cogfrenzy's Construction Toolkit, a reward from Cogfrenzy's Construction Frenzy. You get 1 Pressure Relief Valve in the container, and you'll need 3 (of your own, which means completing this quest three times, or 1-2 in combination with a group) to summon the rare Doppel Ganger, which is required for Rest In Pistons.

Summoning Doppel Ganger

Use the Pressure Relief Valve on one of the pipes. If you have 3 Pressure Relief Valves, you can attach one to each, or you can group up to complete all three.

Note: activating the Pressure Relief Valve is a 2-step process, one interaction to attach it to the pipe, and another interaction to activate it. When you've successfully activated the Pressure Relief Valve, you'll see a notification that "You hear gears turn beneath the ground."

When all three pipes are active, you'll see the Doppel Gate form. Once you see that gate, someone needs to walk into it to 'summon' the rare.

Details, if you want them: This creates many small clones of the person who walks through the gate. The rare is an event, rather than a mob.

This has nothing to do with the Doppelganger rare which is required for Rest In Pistons.

It appears that you can only use this on days when the Construction Frenzy daily is available. If you happen to see these in your bags & go off to clear them out, the event won't be available to interact with, if Construction Frenzy isn't on for the day.

I can't be the only one who thinks this is a Half Life 3 reference.

Once you have your three Pressure Relief Valves:
Use all three Strained Exhaust Pipe/Strained Exhaust Pipe/Strained Exhaust Pipes.
Use all three Pressure Relief Valve/Pressure Relief Valve/Pressure Relief Valves in the middle of said pipes.
Use the Big Red Button that appears in the middle.
Doppel Gangers then emerge from The Doppel Gate.
BTW The Doppel Gang is a hidden quest, you don't have to accept it or turn it in. It's like an (invisible) wold quest in that regard - you do the stuff, and you get the (meagre) reward.
BTW BTW, even though the Valves persist in your inventory after quest days, the pipes are only accessible on on such days when Walton Cogfrenzy is in town.
