Ibergrif M20522 Toilet Dual Flush Valve with Button, Suitable for 2 Inch (Φ59-61MM) Toilet Flush System Replacement Adjustable, WhiteGlobal Recycled StandardGlobal Recycled StandardGlobal Recycled Standard

Excellent product, very easy to fit and does its job. Clear, easy to follow instructions as to how to fit it included.

Good quality and I was able to fit it myself. Still working 6 months on. Filling speed is quick.

The plumber who fitted this found it easy to fit and adjust, it works well and feels solid, and a nice feature is that the cable that connects to the loo flush push buttons is clip-on. That makes it easy to remove the porcelain lid on the WC water tank for cleaning and servicing in the case that the floater breaks. This syphon was sourced as a replacement for a Geberit syphon which is not available anymore. It does not come with a floater but the plumber had one in his van, a standard model.

Absolute fantastic product the ibergrif M20521 for the price and allowed a first time DIY attempt at plumbing to go wonderfully. Very easy to install. Build quality is better than the one I replaced as its copper and not only plastic (see photo of old grey one installed in new build 2017). No leakage even though I used no epoxy and just hand tightened the parts together. Only thing that was also needed was a reducing bush to take the larger size water pipe down to the G3/8 size of this fill valve (see photo). Bought for a euro in Screwfix. Fits perfectly and fills up much quicker than before. Noise level is standard and as it fills quicker it gets quiet quicker too!I've now bought 2 more to keep as spares for the other toilets in the house.

Couldn’t get a fitting to fit this to my toiket

Instructions to fit easily. Great price good quality and brilliant replacement part.

Doesn't fit UK cistern. Well not my one.

Ideal fitment for a cistern with a 2inch outlet worked like a charm. Previous unit that had failed had to be siliconed in, this one sealed tightly and has worked flawlessly since installing. At £13 including same day delivery beats Screwfix hands down that didn’t have a suitable 2inch outlet at anywhere close to the same price point.
