Flo Thru Heater HELP

Home >

 To determine if the element in a flow-thru is bad, test it the same as you would a regular element. If the wires have been removed, check it for continuity. You should see approx. 9-11 ohms of resistance if it is good, maximum resistance if bad. Be sure to measure the resistance between a post and your ground to make sure the element is not ruptured. You should see maximum (infinite) resistance if it is good. If the needle moves at all on the meter, you have a rupture in the element sheath. You would need to replace it. The continuity test to the ground is best done when the manifold is full of water.
