Yesterday when I unscrewed all the white knobs one of them cracked and broke apart so that is a weak point.

Turned on the filter and that's exactly where the leak is were that one knob is not tight.

Would buying all new knobs be okay?

Or is this leak something else?

those white knobs are flimsy and you need to be careful when unscrewing them. i've broken them before. you'll need to buy new ones and they're expensive.

I had the same problem but I bought replacement red knobs and they actually work way better imo. The red knobs I believe are from the older version but they are easier to tighten and loosen as opposed to the triangular shaped knobs.

The problem is the little barrel at the bottom on the bolt. Over time they start to split and then the whole knob becomes useless.

You do not need to buy an entire knob assembly. You can order just the barrels.

Here is an example, not saying this is the best priced just showing that they can be purchased separately and repaired: https://www.ebay.com/itm/2852289723...18XhZrJKpqnK5PLmNQha6JgEH1831N1RoCuKQQAvD_BwE

Or another option is to look up the file and have someone 3d print them for you. This is what I ended up doing. My brother had a printer for his modeling hobby and I found a file and he printed some out for me.
