It should be able to handle it no problem, especially cold water. online data says good for 1Mpa (mega pascal) or about 145 psi.
Wow you beat me too it, so 145 would be ok, so then what, if it leaks I want to know big time, so maybe 30 psi, don't want to blow up the gauge.
Can anyone tell I'm a bit nerves.. lol
I would isolate any device not capable of test pressure, including the boiler. If the pressure gauge only goes to 30 psi, then it should be removed and a temporary gauge installed.
I would test to 1.5 times working pressure or at least 45 psi. Pressurize the system, valve off, and hold for about 1 hour. If no pressure drop, then test ok.
