How to inspect this fill valve

[staples]

I'm frustrated that my fill valve looks like nothing I can find on the internet. It seems to be a variation of an "internal" fill valve.

See attached photo.

This won't stop filling the tank, so I'd like to inspect the valve seal. I have no idea how to get inside! Should the entire "cap" come off?

The gray floater assembly is attached to the top with two tiny plastic pegs. Similarly, there are two more plastic pegs at the base of the floater.

Thank you for any help.

Not sure if Canada uses different set ups? Sorry I'm not familiar with this either. Does your toilet clog a lot? If you get clogged with this toilet every now and then, you can just switch it out to a 1.6gallon instead of this 1.28 and then you could solve two problems.

If you don't get clogged toilets much with this 1.28 then you are right that it should be easy to fix or replace the fill valve but I don't know where to start. We only have a few main brands of toilets here and they all seem to use one of 2 types of fill valves for the most part.

Hi Rick. Thanks for the reply.

Not a different set-up, just a relatively rare fill valve style (frustrating - this would have been so much easier for me, a newbie!). I have the same model of toilet in my other bathroom of a recently purchased condo and it has a standard-looking valve with a red top and lever. Possibly someone already switched out this valve in that toilet?

I finally found the video(s) I needed, and deduced a part number.



I had put a rubber glove on my left hand to get enough grip on the shaft to rotate the thing off, and the tank is small, making it difficult. I had to put pressure on the shaft to do that. (At this point I was thinking "I'll be calling a plumber anyway, and if I do I'll ask for a new valve, which he'd probably recommend anyway", getting a bit desperate)

I cleaned all the parts - there are three pieces of rubber involved in this model, vs apparently two with most, and I actually thought the seal had broken clean under pressure into an inner and outer ring! no, two pieces! thanks to the video above - put it back together, and never expected the flush to change... there was no basis for anything to have improved... but it did. For now, it's fixed! I would have bet against it.

I don't know anything about this stuff beyond Youtube Help, so it's a small victory (knock on wood) right at the moment of seeming defeat.
