FHW testing pressure

in THE MAIN WALL
I have installed some new baseboard with 34 inch copper pipe. Before I connect it to the system I would like to test it using compressed air to find any leaks. What is the best pressure to charge the line at and how long should I leave it charge? Thanks everyone.

    testing

    We alway test to 1 1/2 times the operating pressure, or more. Be careful with air and don't trust it totally. Air can and will find a leak and stuff debris or flux into the hole and plug it. Put the water to it and there's a leak. have had it happen before, but generally is a safe way to test. Just don't assume that standing pressure for 20 minutes or so is enough proof. Keep a careful eye as you fill the system.
