Home Made black water tank

The straight one would work. You could drill your hole through the wall inside the sink cabinet then use that flexible hose that they use on garbage disposal vents.

Unfortunately, I already have my hole drilled and the 1/2” valve in the wall. However, I have tracked down a 3/4” one on amazon (never showed up before) as well as a 1” one on eBay. I have both coming. I’ll see which one is easier to retrofit.

Before you drill a hole for the 1" vent, be sure that you can find 1" hose. 1" is hard to come by.

No worries 👍
