Review: Great item - smooth transaction. Great item, easy placement. Took 2 minutes.
Review: Excellent product, easy to install - Just bought this and have no plumbing experience, fitment is very easy and I didn't need to turn of water mains as water just runs into toilet. I unscrewd the old unit and installed the new one it took 5 minutes, well worth money as it will save you having to pay a plumber. When I purchased I new the brand was correct but couldn't of been 100% sure it was going to fit but it was cheap enough to take the risk on.

## Questions & Answers

**Q: Does anyone know if this this the same unit as fitted in the Karat 279?**
A: I don,t know

**Q: Do you have to hold the button down for a few seconds do do a proper flush or just press it**
A: It only has one flush function. Press and it does a full tank flush.

**Q: Can you unclip the bottom of the cylinder to fix to existing part?**
A: Sorry bit confused,do you mean take existing part from cistern and connect new one ,if so yes i think its a quarter turn and lift off,drop new part in and turn to connect.I only wanted the chrome push button from the new flush unit but i have removed the top section in the past to clear scale from the seating washer to stop water dripping into the wc pan,hope this helps .

**Q: Can you replace the seating washer by simply turning the unit anti clockwise..Or do you have to remove the entire cistern?**
A: You just turn top portion i think quarter turn and lift off of fixed section ,no need to remove the cistern thats the beauty of this new type of flush valve really very simple.
