Yours might not but what if everybody on the street decided to use one.
This is what its meant to stop.

But that isnt what he said

Its about a 2 grand fine for putting a pump on the mains,reason being it zaps everyone elses supply in the street.
You can only pump from a holding tank to your RO and not direct from mains,its fairly serious tbh

[robert mitchell]

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 .

Checked with my water company years ago, said you cant pump direct from a tap

YET
if you buy a pressure washer, are we not breaking the law
(Is this not a booster pump attatched to a tap)

Good point.
But maybe the pumps in domestic rated pressure washers are less than 12 ltrs per minute?
(The WRAS regulations state that less than 12 ltrs per minute is acceptable).

Flow and pressure aren't the same thing.
 Booster pumps are increasing the pressure and dont effect the mains flow so surely it wouldn't effect anyone elses supply...?

flow and pressure are not the same thing.  You up the pressure for a given flow with a jet wash by making the outlet smaller. If you want to up the pressure of water in a half inch hose for your tank without losing flow then the flow must be greater. Baffling myself now.

N.V.Q 2 plumbers book clearly states no pump should be conected to the mains.  A holding tank then pump is the way it should be setup, the same set up with a cylinder in the loft providing a shower pump.

Not to add fuel to this fire but I think I'm right in saying that a plumber isn't to fit a radiator in a conservatory (definitely not in a new build) but that doesn't mean it can't be done.
Perhaps it's the same sort of thing where a plumber isn't supposed to do it but that doesn't make it illegal or whatever...

I'm sure plenty of people use pumps off there outside tap , chances are nobody is ever going to find out or even care .

anybody who is worried about it can just feed the tap water into an ibc with auto cut off then pump from that .

if your outside tap already comes from a water tank in your house then you have no problem .

mine runs from my washing machine inlet (fitted a double adaptor) which is supplied from my water tank in the roof .
