I have an Aqualisa4+ power shower, which is in a spare bathroom and very seldom used. We recently used it and on cold there was plenty of water pressure.
When tuned to warm the low pressure light came on and the flow reduced considerably and no warm water came out. Is this a common problem and how do I solve it.
we have 2 bathrooms the masterbath has a stand up shower and a garden tub the tub works fine but the shower when turned on hot barely comes out but when turned on cold it is full blast any help
