Review on 💡 Aprilaire 4040 Solenoid Valve Voltage by Vincent Lott

My original solenoid started making a loud noise that could be heard throughout the house as water was flowing through it. Works well - just loud. I bought this because I thought I would be doing myself a favor by buying a genuine Aprilaire piece. It was October 2020. Tonight I went into the basement and found a large puddle of water under the humidifier. Upon closer inspection, the water was flowing quite heavily from the back of the solenoid. Luckily I saved the loud original for just such an occasion, removed the replacement and reinstalled the original.
