Thomas Dudley 327628 Niagara Vantage Valve for Both Single and Dual Flush, Green, White

Perfect replacement for siphon system we have. Only issue was the box it came in was wrecked but product not damaged so no issues. Easy to fit.

Brilliant seller,new part arrived pronto! Easy fit ( thank god..) works like new. Well chuffed. I know where to go now for loo bits!

Great product. It fitted perfectly in place of the worn out Syphon. The only disappointment was it was badly packaged, so the box it came in was collapsed.

After years of use this unit was becoming unreliable, fitted a new unit and all good again. Have a play with the unit before fitting and see how the bayonet lock works, take notice where the old unit lines up before removing. Ours is in a fitted unit with a removable panel so quite restricted access. Do it while the house is empty - nobody to hear you swearing!

Simple job but fiddly to manoeuvre new body into existing bayonet fitting (be patient and take your time). Very quick delivery and works a treat. If replacement, check overall height and swap new top cover with old if necessary. Note: 3 year warranty if product registered on-line. Design improvement on original.

I needed a replacement as toilet not flushing very well. I had to use this as a direct replacement and I don't think the new one is much better. I also replaced the vacuum button. Part of issue is the flush is not as powerful as needs to be and while 6 ltrs should be enough it doesn't always shift waste. If I could find a different cistern I think I would try that.

Item was classified as used, the description said only damaged packaging so I bought it at a cheaper price. All was good with the part itself and it fitted perfectly (direct replacement for the same part)

the part was a much better improvement on the one we were replacing, and the supplier was very good, delivered next day. A bit of a bugger to fit though, needed baby size hands to get into the small space. That apart works well.
