Discuss Have I dropped my self in it here? in the Plumbing Jobs | The Job-board area at PlumbersForums.net
what we have been taught and what i have read from multiple publications..is..
in the event of any pressure drop during the 20mb phase of the tightness test all appliances must then be isolated and the carcas tested in isolation to establish if the carcas is leaking. Wether existing or new - no carcas pressure drops are permissable.
Indeed Only if it is found that the appliances are causing the pressure drop then do we fall back on the specified allowances Re permissable leakage/pressure drop based on meter type etc.
In essence thats what they state
I can post the screenshots from the publications ..
But my viper book doesnt go into as much detail lol
