Review: Excellent replacement - Works better than the one I purchased from screwfix. Still working well 1 year later.
Review: Well impressed - You wouldn't believe what small thing like this can do . There didn't appear to be anything wrong visually with the old one.

## Questions & Answers

**Q: Are these in fact genuine siamp valves. i ask because they look grey (unlike previous orders) and have no siamp markings.**
A: I don't know if they're genuine Siamp, but the greyness comes from a fine powder that seems to have resulted from the manufacturing process. After installation and a few days use they appear as black as the originals.

**Q: is it fit for toto model c945?**
A: I don’t know what specific toilet box mechanism they fit but i do know that they were an exact replica for the valve seal that was in the toilet box originally and at a fraction of the price. 
So if the one’s in the picture’s look like your old ones I would say yes but that’s just my view.

**Q: These look identical to the one I've removed from my cistern but they don't shut the water off. I place the old one back in and the water stops. Y?**
A: These are meant to let the water through until the cistern fills and then the float arm will shut off the valve. Check that you have connected the float arm correctly.

**Q: hi, what is the difference with 34951309? look like this**
A: I don’t think there is any difference . I’ve fitted these and they work fine.

### ⭐⭐⭐⭐⭐ Excellent replacement
*by A***D on 11 January 2026*

Works better than the one I purchased from screwfix. Still working well 1 year later.

### ⭐⭐⭐⭐⭐ Well impressed
*by M***L on 23 March 2025*

You wouldn't believe what small thing like this can do . There didn't appear to be anything wrong visually with the old one. Our cistern was taking about 30 minutes to fill after flushing. So after watching a YouTube video on our Syphon we ordered these. Fitted in minutes. The Syphon works like new, filling the cistern in less than a minute. Well impressed. Recommended.

### ⭐⭐⭐⭐ It works but only if you use the old washer for parts. Unlikely to be genuine SIAMP washer.
*by S***E on 28 December 2025*

This worked, but it needed modification. I'm not sure if these are genuine SIAMP diaphragms. My old diaphragm washer was split (apparently this happens, causing the cistern to take a long time to fill) and I installed the new part. I took care to line up all the line on the white insert with the gap / notch in the valve assembly, and to ensure it was seated correctly before closing the plastic nut. The cistern filled quickly but didn't stop filling when the float arm was raised. I ended up having to take the old white insert (with the pointed cross end, seen in the middle of the rubber assembly in the product images) and using it with the new rubber washer. Once I did this, it worked properly. So 4 stars because I got this quickly and it allowed me to fix the cistern filling problem, but only because I had to use the original split valve for parts. Shame it didn't work right out of the packet....
