They doesn't seem to be a water pressure issue in the house, most of the time - it's just the cisterns that seem to have serious issues.
They're approaching about 20 years old...
Any suggestions ?

Some toilets have 'quiet' fill systems - i.e. they fill slowly to keep the noise down. Others have the ball-valves badly adjusted, so that they don't open up properly. Typically, when the washer starts going some people will bend the float arm to force the valve to shut off. This also reduces the opening on filling.
Now I think that toilets are normally fed off mains pressure water - wonder if these are being fed by a header tank? That's pretty low pressure.
Alternatively, are there stop-cocks for the cisterns? Maybe these haven't been fully opened in an attempt to regulate the relatively high mains pressure?
