Yes those should be perfectly fine to use. I used them for years on my stock tank sump setups. Polypropylene is extremely common, used in many many food safe items/containers.

Dang! I thought the male that we adopted was a big boy, but he's not quite 100 lbs. My avatar is of my female, she's basically attached to me at the hip. They are great, loyal, lapdogs! I grew up with them and always wanted one again, somehow ended up with 2 and a little brown dog too. Haha

Good luck with the bulkhead swap! Nice thing about those is they are pretty darn heavy duty!
