Flexi with the built in iso valves are stupid!The bend in your flexi is too high because the connection point for the flexi is too high and your hose is too short.
I'd use a flexi hose with a built in iso valve which would lower the connection point to the compression joint where your iso valve connects on to the the copper tee and would make the bends smoother.

The fact you are asking means that deep down you know it isn't quite right??
Depends why you're fitting the iso valve. If you're fitting it to make install easier and to allow you to disconnect whatever the flexi is connected to at future date, they're not stupid.Flexi with the built in iso valves are stupid!
The iso valves tend to be poor quality for one thing and I'd rather have the option of changing the flexi on it's own if needed which might be more often than you realise.Depends why you're fitting the iso valve.
