What's this press fitting brand?

Google lens says Viega Megapress.

Anything else I can use to make alterations as cold mains supply from UV combination valve is blocked somewhere and all cold outlets from it are non running... It's all in the walls and floors!

I'm going to try to backflush it later today but preparing myself for potential repiping too!

Any pushfit fittings that would fit it or will it need pressing?

What tools and fittings would suit?

Cheers

Can you take some clearer photos? Maybe set the timer and prop the phone up so you aren’t struggling to hold it still

Battery was nearly dead and flash wouldn't work lol.

1st pic is pretty clear.
I'll be back there at 9:30 so will see what's printed on the pipe.
