where to get replacement nut for float valve

[Steve G]

I have a float valve from a DIY ATO I made many years ago. Just tried to pull it out of storage and use, but it's missing the small plastic nut to hold it in place from the outside of the reservoir wall. Anyone know where you can get one of those? I have one on another float valve I'm using on my mixing station (see pic) for reference.

hd and lowes has drawers of special misc of plastic bolt/nuts. take your float valve with you to ensure right fitting.

Just a followup to say that I ended up just buying a whole replacement valve on Amazon for like $9. Turns out you need not only the nut but there are two parts to the washer (I forget the names of each) for the whole thing to work without leaks.
