B & Q 22mm ball valve with a narrower bore on the exist do these cause the flow of water to slow down ? I am using it with a small inline pump.
Not sure if it's affecting my shower don't want to waste my time fitting a full flow lever valve if it's not going to be a noticeable improvement .
Any views ?
