Thanks could you rephrase that with red tank , white tank, left or right...about the level of my experience 😊 so I can point it out to them, thank you...
yes not a problem

White pipe coming out the floor plastic around 11/2 dia

3rd from the right going to the left
Hi Guys, they are coming to fix the diagonal heating zones tomorrow. Please could I have some more info in respect of the white pipe issue above. I attach a few more photos, it looks like 2 bits of plastic pipes stuck together one thinner than the other. Do these photos help you identify whether it is the correct type. Don't want to be fobbed off, so any technical phrases or standards that have been contravened would help. Thanks in advance.

If you lift up the carpet where it goes through you might be able to see how it’s joined below the floor eg elbow

If you see this (wrong) normally abs or pvc

This (correct ) normally polypropylene

It’s a Hepvo valve (like a trap, but waterless). Probably has the condensate running into it. As per Shaun, should be in solvent weld
 
Push fit on conduit pipe?

On an unvented discharge eg d2 pipe yes most new builds are just solvent eg glued which it can’t be on an unvented

Sadly lifting the carpet doesn't help (see photo) but I think it is going straight down, to be clear are you concerned about the material the white part directly above the carpet is made out of? The wider plastic pipe with the logo on it seems like a much better quality plastic, the thinner part with all the marks on it looks like a much cheaper pipe. Sorry if that sounds stupid.

Could you get a torch and see if there’s a fitting down there ?
 
Also based on the original photos of the boiler and tanks, i don't know if there is anything in the loft, I am guessing not. What type of a boiler system do I have is it Combi, system...etc, I have tried following the diagrams on boiler manufacturer websites but I can't find one that looks like mine....
 
Heat only
Unvented cylinder and 3 heating zones

Used an endoscope camera...this is through the gap in the previous photo looks like another bit of board followed by a black pipe..

Down, up and hot water cylinder
