## Questions & Answers

**Q: does this come complete with replacement button?**
A: Hello Jerrytaff. Yes, the mechanism comes complete with a new flush button - I have a complete spare unit in front of me so I'm sure of my facts. (Apparently there is an OPTIONAL extra chrome escutcheon but that, according to the instruction sheet that comes with the new flush unit, is not always supplied; neither of the replacement units that I bought came with this extra chrome escutcheon. This extra escutcheon is about half an inch deep and I don't know why anyone would want it. If there is one fitted to your existing flush unit then just retain it and re-use it.) Further info. is on my review on Amazon.

**Q: Why have you made 3 the minimum order qty? Who is likely to need three of them?**
A: You are quite right. Rather than buying from the buy box, choose a single kit from one of the other sellers.

**Q: Hi can you purchase the top button mechanism separately, as we have had ours in for approx 5 years and the mechanism has fallen to bits**
A: You can buy the button separately ie the silver thing that screws in to the top. Any further down than that requires the whole unit to be changed. The very bottom bit rarely needs changing so you can leave that in the cistern. Twist the unit to the left and put the new one in. Easy peasy

**Q: Will this fit a cifial toilet**
A: No
