Customer Reviews

replacement solenoid valve

I needed a replacement solenoid valve and I ordered the Aprilaire 4040 humidifier solenoid valve from Westside Wholesale. The product was shipped to me in 48 hours. I called a technician and it took about 20 minutes for him to install this device. I like it because of its high performance, good quality and the low affordable price. Thanks!
