looks like the overflow above has leaked in the past as well. possibly toilet?

 

[Colobus]

Excuse me?

Excuse me?

look at the picture, as well as the overflow of your customer leaking, there is staining on the brickwork from above.

Sorry my 'excuse me' wasn't aimed at you- it was in reference to the person about who thought the best advice they could give was to tell me that I should have gone to Specsavers! Thanks for your help so far though- do you think the entire mark on the wall could have been caused by the overflow above leaking? Or that perhaps they both are? Thanks!

 

[PlumbBobBob]

I think they both have been at one time just the lower one now

Yes it is- just a cylinder underneath the tank.

If there's a cold water tank as well as the cylinder, it's not unvented. I would respectfully suggest that you team up with a more experienced plumber on this job. You'll gain a lot from doing that...

See- told you I was a newbie! Have asked someone I've worked with to come round but he's not free for a few weeks. Thought I'd ask here in the meantime. Thanks for everyone's help!

Good on you for asking but do please be careful. If you're that much of a newbie that you haven't yet learned the different types of cold/hot water systems (week 3 or 4 of Level 2 if my memory serves me right) then I would be very wary of working in peoples' properties. You may not be able to identify which pipe does what, and end up cutting into mains, for example. Or something may go wrong which you won't have the skills or tools to fix and end up causing a flood..
