Answers our Mississauga crew gives most
Will the water be off during a backflow test?
Yes, briefly. Supply through the assembly has to stop while gauge readings are taken, so we pick a quiet moment with you.
Does every business need a device?
It depends on the use of the property and local rules. Check the current Region of Peel cross-connection requirements.
