Installation Tips

  • Before installation, shut off the water supply and disconnect power to the furnace and humidifier.
  • Note the water flow direction indicated on the original valve body and install the new valve in the same orientation.

Excellent quality
Size: Large, Color: Purple
Perfect tuxedo to use for many functions. Got it about 2 years ago and have used it probably twice for galas as well as awards programs. Fits to size and didn’t break the bank. Texture is good and it is easy to pair with anything as well as is reusable.
