Did some of my layers with coco choir instead of sphagnum moss this year. Working well so far

So went through the parts bin to get something slightly different

5 year old house. Backflow preventer filled up with water. Managed to track the leak back to the irrigation valve at the inlet threaded part.

Can I just tighten it or should I replace the whole valve?

Had the annual inspected and the box was full of water. Inspector thought it was rain water. I siphoned out all the water and it’s slowly filling back up. Telling me the valve is probably leaking. Is this a diy repair? Replace seals etc?

Any idea what type/brand this preventer is?

How many of these 1gram bars should I get for end of the world zombie apocalypse scenario? Plan to get 1oz bars later on.
