Ibergrif M20521 Toilet Cistern Bottom Side Fill Valve Adjustable Telescopic Urinal Flush Valves Parts M13-17 (3/8") Plastic & Brass Multi Color

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

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.

I have a standard Irish toilet and I wanted to get a push button system instead of a lever (young kids, struggling to use it). Saw this at a great price and said I'd try it. It arrived the next day (I have Prime) and I went about installing it. All was going well until I came to the coupling plate (the silver bit that connects the cistern to the toilet) because this kit does not include the plate, and the one that is used on standard Irish toilets is too small. I COULD NOT get a plate to fit over the new fitting in any local plumbing supplier (as it is a EURO size) so I had to improve and make the hole on the old one a bit bigger with the help of the hacksaw. Once I got this sorted, it was a breeze. It works really well but perhaps the button push is a tad on the hard side to push. All in all, it's good but be aware of the dreaded coupling problem.

I ordered it by accident without checking, the thread was too small, but the quality was high, there was no problem with returning it

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

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.

This product does not fit into a 2inch hole but read the instructions carefully as it requires a 59mm to 62mm dia hole

Just a quick note, make sure your current cold water inlet fits the 3/8 connection. I forgot to do that and ended up having to shop around for some connections to make a feed that makes it fit the BSP connection.Besides that, installed great and been working couple months no issues.
