I bought and installed a whole home humidifier. The humidifier is located in my attic connected to the air exchanger. The Self-Piercing Saddle Valve is located there as well to draw water to the flow through screen. Since the valve is at the highest water point, I seem to get suction around the rubber gasket and air gets into the pipe and I have to flush that zone every day or 2. Is there an alternative to the saddle valve?
I had a self piercing saddle valve on my whole house humidifier when I bought the house. It had developed mineral deposits in the piercing hole and no longer worked. I ended up taking it off, cutting the pipe and sweating in a regular valve. Self-piercing valves are notorious for clogging up and also for eventually leaking. Since it is in you attic, any leak would drip down onto you ceiling and cause water damage. I would consider replacing it with a regular valve.
