Plumber fitted it and it was faulty .(no hot water)
None in stock so had to get my plumber back on another date when new one delivered to store.Although i know these things happen didnt get no apology or nothing.
No discount just inconvenience.
The 2nd shower is now ok though.
Bought to replace my old shower and this was very easy to fit.
Instructions easy to follow and only slight criticism is short period of water dripping from shower head after switching off
