My shower and bath tap have loss their water pressure. Its so bad that its impossible to have a decent shower. The bath spout and shower head are operated by a mixer. We have taken off the shower head in case it was that but the pressure is still too low. It is also difficult to control the temperature. The water is always too hot. The toilet is taking a lot longer to refil and the sink tap also has lower pressure than usual.
Could it be a limescale problem in the pipes as we are constantly having to de scale the shower head and taps in the bathroom. Any help would be gratefully received.
