I thought you couldn't pump mains legally?

[WaterTight]

So why is this allowed to be installed?

Salamander Pumps HomeBoost HB Booster Mains Water Boosting Pump 1.6bar

 

[WaterTight]

Is it because it's limited to 1.6 bar?

Thought it was the amount of water per minute that is limited.

Should be limited to 12 litres per minute.

Is it because you are allowed to, subject to the water undertaker's permission? Although manufacturer's website claims you can pump up to 12l/m and this pump is limited to 12l/m. Need to re-read my blue book (again!)
