Review on 🌬️ Protect Your Backflow Preventers from Winter Damage with the 16”W x 20”H Insulated Cover Pouch – Ideal for Irrigation Backflow Valves! by Sean Liu

This product is very well made. I find the packaging size (20x20) larger than my reflux tubes, although this doesn't really affect the functionality of the product. And I'm pretty sure it will fit any future check valves I have. The velcro is well designed and provides a snug fit at the open end of the bag. Alternatively or in combination, you can put a lock in the sleeve holes or simply close them with a cable tie. Finally, the color of the product (sand) is very neutral and doesn't stand out, which is great. I am satisfied with this product.
