Installer wasn’t happy with the set up. Pipe doesn’t stick out far enough but they will “make it work”. 

It works somewhat.

Update. It works now. The hot water wasn’t strong coming out of either unit. It turned out that it was yet again installer screw up. There was sawdust and debris in the unit that caused the flow to be low. This also happened in the sink but they fixed that. I had to spend more money on a professional to fix the installers mistakes. Unfortunately it wasn’t the only one. We used the same installer we had at another house and the work was great but something happened in the years since. Make sure you get a contact before starting any work. No we didn’t go with the cheaper option we went with someone that did work for us before.
