## Questions & Answers

**Q: Does it keep rain water out of house, or just keep other thing?**

A: The caliber is precisely 4'', but you can dig a hole slightly larger than 4'' and you can install it precisely.

**Q: How it helps me to keep the wind out of my room？**
A: Adding a ventilation fan, using a hose and air outlet connection to pull air out of the room and out through the roof cover, is our recommendation.

**Q: Can I use the flexible hose, I'm afraid it will slip off and I have to buy an extra clamp to fix it?**
A: This is the precise 4" air outlet, purchase the same caliber hose to install firmly. And use clamps to make it more. secure, this is a good way, you can also use tape wrap, I have seen people do this.

**Q: We usually have a few feet of snow in the winter, is this product appropriate and will it clog up from being snowed in?**
A: It does not happen, the heat from the exhaust of the fan inside the house will melt the snow around it, I have really experienced.
