Vaillant External Pipes? (Outside Wall) & Pressure dropping help

Hey, our boiler has started to slowly drop pressure and would like to do a few checks before I call an engineer.

What I have done, I have briefly checked all the radiators for leaks, PRV doesn't seem to be passing, checks for leaks inside boiler.

There are 3 pipes on my outside wall, one being the PRV, one the flue?? and the other was a white PVC pipe that has been directed over guttering/drain. This was blocked and the end of the pipe was submerged in water, I have now cleared the drain so the pipe is free. Any ideas what this pipe does and would it being submerged in water effect the use?

Also worth noting I don't think the boiler has ever been serviced or checked over, not sure on age but I'm gonna say 10 years old.

Thanks

The make and model of your boiler would helpful. Also a picture showing where the 3 pipes in the outside wall connect to your boiler. Out of curiousity, how did you check for leaks inside the boiler?

Thanks for reply.

I will get some photos when I'm home.
I removed the cover and just done a visual check. I couldn't see any obvious leaks.

Pressure seemed okay all day today, radiators and water is heating fine.
If theirs a leak I imagine it would be minor as it probably happened twice in a week.

I haven't tried bleeding the radiators.
