In my area it is excepted, but I would like to see the hose fastened on the water better than tape, such as some screws.

Screws are required at the hood connection ,and you need double wall in an un heated space.
Due to condensation issues.

Here is a good article.

Screws are not required and should not be used on B-vents, as they are self-locking. This appears to be a B-vent, but I can't tell for certain. If it's not, it's improper. B-vents are required for heat vents in the attic or other concealed locations.



IF YOUR INSPECTOR IS NOT USING THERMAL IMAGING, YOU'RE NOT GETTING THE WHOLE PICTURE

Richard that venting doesn't look right to me. it appears that a short section of 4" flexible aluminum chimney liner has been attcahed to the b-vent with tape. Tape is not an acceptable way to secure any type of vent pipe servicing a gas appliance. Screws are required at the water heater draft hood and this b-vent to flex connector is used to connect the flex (see link) Jefferey is correct that b-vent should be used for the entire length. The b-vent exiting the roof doesn't appear to be properly secured or straight.

From that picture the hood to vent connection looks crooked and dependent on tape.

They are actually single wall rated as double wall. Look at the connections as they are self locking and single wall are screw together. On the connections is the rating sticker. I see it all the time and have it on both my furnace and water heater.
