We had two Grohe handshowers installed in two different bathrooms, and are getting rusty water from both of them for the first several seconds of using them each day they are used. They were both installed in addition to an existing regular showerhead (with the original copper piping). A new Grohe wall union, new Grohe valves and new piping were also added (copper in one bath, plastic in the other). The handshowers were installed at the end of Aug 2008, so it's been a little while and we've used them a lot. Any installation debris should have been flushed out a LONG time ago. The problem is not coming from the handshower unit or the hose, because when I remove the hose from the wall union, I still get the rusty water out of the wall union. However, I get NO rusty water from the showerheads in both baths and the tub spout in the other bath (no tub in the first bath).
Anybody have any clue what might be going on? The installers said I just need to flush out the lines. Yeah, for how many years? That's not the problem.
