I had an Aquatronic 4 shower fitted about 4 years ago and it now keeps reverting to low pressure and going cold even though the water pressure does not change. It doesn't matter which button you press it still reverts to the same. If you wiggle the shower unit about it eventually comes on but obviously there is something loose inside. Can this be fixed or do I need a complete new shower unit
