How do I set the water valves

[JOB6]

In my bathroom cupboard there are pipes and valves which control the hot and cold water in a second floor flat ( under the kitchen sink there is no shut off valve)

There are three valves (two control the hot water which feeds into my kitchen sink tap and all bathroom taps) and one controls the cold water feed in the bathroom and kitchen tap.

The water flow needs to be set as the pressure is not right and this happened in my previous flat that I get a rash whenever the flow is not right, when I open the valves fully and the water pressure is too high my rash worsens. My question is how do I set all of the valves in particular the hot water flow rate, should I get a plumber to do this as I am not sure when to stop turning the valves and when to stop as I have nothing to measure them by?

Any advice would be great thank you.

Stop turning them when your rash goes away...

Just adjust a little at a time until you're happy with the flow rate. Nobody here can tell you what you find to be acceptable

Thank you for your advice, I turned the red valve which controls the hot water and my rash (looks like hives) has slightly cleared up so I will continue to turn it until I find the right flow. I wonder why the rash appears and disappears when I turn the hot water valve any ideas I don’t think it had been turned in over 40 years.

Are you saying your rash gets worse when you physically touch the valve?
Turning the valve one way or another won't have any effect on the water pressure.
Why don't you regulate the water flow using the bathroom taps instead of using the service valves?
So you were able to turn the '40 year old' valve?
First port of call would be to make an appointment with the quack.

I tend to get a rash when I touch washing machine/iron/Hoover/washing line/pegs....

I tend to find marigold gloves on the better half help with those kinda rashes

Great suggestions thank you

On a serious note Job, it's not something that comes up often in our trade.

If you are getting a rash then it can really only be 2 things. 1 you're allergic to something in the water or you have hyper sensitivity. Either would need a doctor or dermatologist to investigate. The water flow would only be incidental and not to do with the underlying issue I wouldn't think

Any idea where the Pressure reducing valve would be? I need to locate it and set it a little bit lower than it is now but I don't know where I should be looking, thanks.

I doubt you'll find a PRV fitted.

 

[JOB6]

So there wouldn't be one in the bathroom cupboard?

 

[Madrab]

Probably not.

Look for something like this or in bronze
