## Questions & Answers

**Q: Water keeps pouring into pan stopping it from filling up**
A: I have only just bought this, and this is exactly the problem I am having. After flushing, the overflow pipe gets stuck in the up position and water keeps pouring into the pan. I don't really want to remove the strainer to return the part, as that means taking the whole cistern off again. Is it possible to just get a replacement for the outlet valve or cable, as a brand new product really should be working?

**Q: I need to know if outlet is 2"bsp, without adaptor?**
A: I can confirm thread on bottom of adaptor is 2" BSP, hope this helps

**Q: can you explain the reason and adjustment for dead water valve and short flush cursor**
A: Download the manual 5496_Notice 50+Robinet_GB from this site: http://www.leagrave.net/file/siamp_optima_50_instructions.PDF, this explains the function of the dead water valve which controls the amount of residual water remaining after a long flush. It also explains the setting of the slide valve that controls the amount of water consumed in the short flush.

**Q: Will this fit most toilets. My system is older button And its faulty?**
A: If it looks the same it will fit. It is very easy to fit with just a twist to remove then a twist to fit.

### ⭐⭐⭐⭐⭐ Works a charm
*by A***T on 3 January 2026*

Perfect fit, sorted out our troubled bog. No more festering waste :)

### ⭐⭐⭐⭐⭐ Great value swap. Reusing old close couple kit as it just unscrews.
*by C***D on 18 December 2025*

Seems great, 5 minute swap for dodgy old one. Comes with long collar for low bogs.

### ⭐⭐⭐⭐ Does what is required although cable was shorter
*by C***K on 11 November 2022*

These are very much made from plastic but in terms of replacing an old one exactly the same it is ideal. Twist off the old one and twist in the new one. Simple. My only problem has been the cable length to the actual button. I needed a shorter 30cm cable so ordered that separately as the one ordered indicated it came with a 40cm plus cable. When it arrived the cable was the shorter one anyway. Didn’t matter as it happens as used the extra one on the next one that broke. Personally I would prefer a more substantial method of flush but you can’t beat this if you want to replace a broken or worn out old one.
