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

This was a replacement for a TD valve. Very easy to fit and works perfectly.

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!

We had an old one of these in a toilet in the house we moved to, it broke, the plastic nozzle where the air line attached snapped off. I tried to fix it with araldite but it was too far gone. This is the only equivalent available now, and it is close enough, but as another review mentions, it fits on to the old innards ok (I only wanted the green bit, I did not want to take the cistern out to replace the entire fitting, that would entail major surgery on the surrounding shelf and cupboards) but it locks in a different position. The old one took a full half turn to lock, this one only less than a quarter turn. This means for me that I could not turn it to the fully locked position because that means that the nozzles where the air lines attach are facing the front and back of the cistern, leaving no room for the tube to go on. So I have not fully locked it on, but this is fine, it won't be moving. The other bigger problem I had is the shape of the top cover. The old one was flat (see pic), the new one is shaped, but it is about 5mm taller than the old one, meaning that the inlet pipe would not fit back in its holding bracket. So I had to use the cover off the old mechanism, which luckily clips on in exactly the same way and aside from the height is the same size. It works great, just be aware if you are replacing an old broken one that it might not be a simple swap.

Can you imagine the cost of this item if plastics were banned....great design, great function...right material for the job

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.

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.

Other Niagara Vantage Valve was over 10yrs old and started to stick when re-filling cistern. This new one was relatively easy to swap over and just clicked into place. No more sticking. Perfect.

Excellent product , used it to replace a broken current TD product. Very simple to fit (5mins) and with good instructions. Excellent delivery as usual with amazon prime.
