Which valve do I need for this

[BobbyJoe]

Thank you Shaun, I was trying to figure out what happens if there are no single/double check valves installed. The cold water is fed via the mains and the hot water via a tank, are there dangers from not having the valves in place?

Got thrown a curve ball when you said contaminated. Not a word I would of used for hot and cold water problem.

If you use water which is cross contaminating is this likely to damage your health?

Sorry I know I wasn't making much sense as I was trying to understand the situation myself and used whatever words came out of my head to best describe it.

No worries, bit like talking to a customer via a phone call, just takes longer via a forum.

Long story but I moved into a flat and within months had come out in a rash, over time my skin worsened (looked like burns) as did my health yet no one could figure out what the issue was. I moved out for a while back to a friends house and my health improved then I returned back to my flat and the same situation occurred, countless visits to skin specialists. The landlord and I had agreed to low rent for a fixed period of time as long as I took care of fixing things which I agreed to as he spends a lot of time abroad, I didn't think there would any issues as he had the place refurbished and the bathroom had a new suite installed.

There was a leak last month and I had a reliable/verified plumber come out, he checked everything and noticed that in the bathroom the plumbing was incorrect and mentioned the words "cross contamination". I told him about my skin etc.. and he said this was most likely the cause, I contacted the landlord who said that "he couldn't remember who carried out the work for the bathroom" and that no one else had a issue with it but then again the flat was empty after refurbishment and along came stupid me.
This is the reason I am trying to find out what causes cross contamination, the health implications and how to fix it.
