not a restriction on the use of water.

So you can water the garden, you can wash the car etc etc
but not with a hosepipe.

So how are you going to syphon the water without using a hosepipe?

A hosepipe ban is a ban on two specific uses of a hosepipe. All other
uses are permitted. You are prohibited from watering the garden and
from washing the car. Anything else is allowed -- including leaving a
hosepipe running on the driveway.

The ban on hosepipe use for garden/car watering applies only to
hosepipes connected to the mains and delivering water directly to
plants or soil.

So you can use a hosepipe to fill a water butt, watering can or any
other container (which isn't planted).

Further proof that the law is an ass: you can use a hosepipe to water
an allotment (because it is classed as agricultural land) but not to
water your garden veg plot.

You can use a hosepipe to have a waterfight with the kids on a hot day
- but not to help grow the vegetables to put on the kids' plates.

You can even use a pressure washer to clean the patio. Is this madness?
How can the Govt spin machine not have foreseen that this will make
them a laughing stock (watch this space when the ban hits Greater
London and all those journalists and TV producers on April 3).
