Flow regulator or isolation valve? Or Both?

[morpheus83uk]

I am making some changes to my bathroom this weekend (well starting it anyway) and Ii notice I will have to stop all water flow as there are no isolation valves anywhere so I am looking at putting some in so this isn't an issue in the future and also once they are on I can put the water back on and continue working...

My question is that I want to try and restrict the water flow to around 8 - 10 litres a minute to the sink and have an isolating valve. I believe that if I use an isolation valve to restrict the flow it causes noise in the pipework or something as it due to pressure or something...

I am wondering does anyone know of anything I can use to do this? and as I have never put one of these in place before I presume I just cut the pipe where I need and add the valve in and then add the other part of the pipe at the top and that's it job done?

I would also like isolation vales on the toilet and the bath and shower (as its a separate shower to the bath) so I presume I can just use one for that and just restrict the flow rate on the sink so that the waterfall taps just continue doing what they do and everything is happy...

I have found the following which should I go for?

http://arrowvalves.co.uk/portfolio/automatic-flow-limiting-valves-save-water-and-energy-afl/

I think the above reduces the flow to whatever cartridge is put in it and then also has the isolation valve on the top which I think would be best...

However these have good reviews too but seem like normal isolation valves which I can use for things like the shower and WC..

Red for Hot / Blue for Cold

So blue for Cold water on Bath and WC and the red on the hot for the Bath..

What are peoples thoughts? Or am I going about this the wrong way?

Thanks

You need a water regulator and it can sit inline with a service valve, or directly on the appliance - several flow sizes are available at -

The isolation valves you linked to look OK but I prefer the longer handled ones shown below on that page, they're less likely to be a struggle when they get a bit sticky.
That's assuming there is room to operate the handle where you are fitting them.
