This fitting must be used as an outlet only on any Tek Tank. If used as a filler and is connected directly to the mains water pressure it is more than likely the tank will fail due to the tank being over pressurised. An internal float valve must be used in this application.
Tek Tanks test tanks to a maximum of 5 psi (depending on the application), water mains pressure can be up to 8 bar, this is 22 times our maximum test pressure.
