I'm installing a Grohe Euphoria 360 Shower system in my new shower. I've plumbed in the wall 1/2" PEX to a brass Sharkbite 1/2 female NPT drop ear elbow.
The Grohe system has the mixing valve outside the wall. It uses a European straight thread and comes with "easy install adapters" with male NPT at one end and female straight thread at the other to convert. You attach them to the NPT with Teflon tape, as any other NPT. Then you attach "S unions" to the straight thread using sealing cord. The process is fairly well shown in this video, starting around 2:35, the sealing cord is around 4:30:
I'm using the S Union that comes with the valve (shown first in the video), not the ones with service stops the video uses. So I didn't need to do the scoring, the parts were already scored. I wrapped the thread just like he showed but I'm getting a slow drop leak from the straight thread.
A few questions:
1 - Anyone have experience with these straight thread connections and know any tricks to getting them to seal?
2 - I'm going to need to pull this apart and try again, where do I get that sealing cord?
Thanks
