## Questions & Answers

**Q: how did i adjust the overflow pipe ? mine is overflowing and i carnt fit a flush master valve [no room}**
A: The overflow is part of the installed system. You don't need your normal overflow pipe - you can throw it away. The overflow works through the plumbing you have just fitted. Try unscrewing the over flow tube supplied - I found that it was too high and had the problem you describe - then adjust the float ball (if necessary) to make sure the level of the water does not reach the height of the opening in the in-built system.

**Q: Anybody know how this unit compares to the Torbeck Variflush?**
A: Both units are from very good manufactures we sell more of the Torbeck Variflush but that doesn't mean its a better product.Kind regards,Jo.

**Q: how to change batteries**
A: There are no batteries it works by siphon alone.

**Q: Is this a complete system? I can't see a ballcock in the image.**
A: No it's not a complete system.  IT is only the flush mechanism.  You don't need to change the float if it's OK.  I fyou have a close-coupled toilet, this requires you to remove the cistern and I recommend you take the opportunity to replace the close coupling kit.
