Just Want to know what psi is equivalent to 7 bar? What is the conversion figure?

Is 7 bar too high for a domestic supply?

Try this: Convert psi to bar - Conversion of Measurement Units (http://www.convertunits.com/from/psi/to/bar)

7 bar converts to 101 1/2 PSI. If this your house pressure it's too high. 45 PSI (3.1bar) is the average house pressure. Good luck, b Tom
