How Do I Replace a Shower Diverter Valve?

[severen]

Hi again,
as per the title, the bathroom has a Grohe tap/shower fixture w/ a diverter.

the thing started failing only a few weeks after installation, had it replaced and now, about 2 years later, it's seemingly failing again; when you lift the knob to activate the shower it's getting very reluctant to divert, you have to turn the water flow up higher than usual, and when finished the knob is not lowering correctly. Is it usual for valves to need replacing this often?
anyhow; is it an easy enough job to replace the valve? Do i need any particular tools?
as for the valve, i believe this tap is called a "Eurosmart" as per this link
https://www.heatandplumb.com/acatalog/grohe-eurosmart-bath-shower-tap-deck-mounted-chrome-25105000
(though in google that name comes up w/ quite a few other pics too) so is that "silkmove 56mm cartridge" the thing i need to find and order?

TIA

Look at https://www.grohe.co.uk/en_gb/eurosmart-single-lever-bath-shower-mixer-1-2-25105000.html . You'll probably need the parts labelled 5 plus the necessary tools.

Ring grohe and have a bit of a moan (whilst saying how much you like the product) you might get a good elf and be looked after for nowt

Yes, Grohe are usually high quality products. Sort of brassware that you pay good money for in the knowledge that if they go wrong in future, you can get parts to fix. That's the whole point, because buying Chinese junk from B&Q that you can't get spares for is a real pain to keep ripping out and replacing. I would be doing as Dilalio says and having a good moan at Grohe.
