This morning the pressure has gone from the while house taps toilet shower hot and cold... We live in Scotland have no water meters and no water softener systems... Water comes straight from the mains

Is there a PRV (pressure reducing valve) installed where the water enters your home. Do you know the mains PSI? Can you find out? Back to you. Tom

Thank you, but problem solved, there was a local burst pipe which caused the trouble... Scottish water hopefully resolved problem by the time I go home...
