“I was a little surprised when checking off the parts in the kit i purchased, it obtained 2 x flow control levers when i didn't order flow control valves. I also required 2 white split rings according to the fitting instructions these were not listed as being in the pack, I can only assume that you need to open and use these out of the spare parts pack which means i no longer have them as spare parts, The white split rings would have been better value over the wasted lever arms.”
