How does it zap everyone's supply ?
A standard fire engine can pump 2300 litres per minute , some can pump 5000 litres per minute to supply Ariel ladder platforms .
They take this from the same water main as the houses and there taps still work .
Even if every house had a 12 lpm pump it's not going to significantly affect the streets water supply .
All they are saying is you should notify them if you do fit a pump .
