The tank in the attic was designed to act as a buffer between the house and the water network. It means that if lots of people have showers at the same time they're using water from a storage tank in their attic rather than the mains. The mains has a chance to 'catch up' with the demand.

It keeps the demand nice and smooth throughout the day rather than having pressure dips and peaks.

Perhaps the victorians didn't specify large enough water mains!

These are seen on the roofs of tall Manhattan buildngs to ensure adequate flow and pressure, rather than torture a pump costantly. I believe the mains can only directly serve fewer than a dozen floors/levels/storys direclty based on the allowable/exisitng pressure.

*WOW* never thought of that. A dump valve on the bottom can assist in a fire.

Older/smaller structures (the buidlngs themselves) are wooden.
