Finally someone explains how this works ("flow this, pressure that") and not the dozens of videos of how it operates ("the water rises and the float closes the valve"). I'm yet to find out how do the ones without center pin (but a small hole that is closed by the float rising) work, but now I can brag about knowing this 😉 Thanks!
Wow, I had no idea! I've replaced those rubber seals a few times to repair valves, and opened up the valves to flush out grit more times than I can count. Yet I had no idea the intricacy of that valve stem. I have one that is slow to start filling (float drops, nothing happens). Sometimes it waits a second or two and sometimes up to 30 second delay before water starts flowing. Now I know where to look!
Thanks for your comment. I’ll be honest. I had no idea how this thing worked either - until I started researching it. The reason I researched it is because I could not imagine how that little metal rod/stem could start and stop the flow of water. I was really amazed when I learned the mystery of it.
I have a fluidmaster, yet NOBODY on youtube has made a video about what the little spiral shaped rubber seal inside the bottom of the unit does. Do you have that seal inside yours? We do in Australia. All i can assume is that its a flow restrictor, or a piece of junk that is purposely put there to break down over time causing one to have to buy a brand new refill valve. My refill valve stopped filling, so i took it out, looked inside the bottom of it and found that seal, it was falling apart. The rest of the valve was working fine.
Yes I just replaced 2 full units only 3 yrs old.. In both the screw in filter in the bottom of the fill tube was obstructed. I suppose that causes slow fill and low pressure, and the top seal that he illustrates, cannot make enough downward pressure to push down and seal. I would be interested in this spiral filter also. BTW just pull out with needle nose pliers. Thanks to both of you!!
Interesting. Just today, 12 oct, '24, i purchased kit #385 to fix a running toilet. I noticed the stem is smooth, as is the one in the existing fill valve in my toilet. I also purchased part # 242 (seal only). After replacing the seal only thea toilet makes no signs of slowing the water after 2nd fliah. Replaced the entire valve unit and I get the same results.
Will this valve still work well in a very low pressure (not mains connected) situation as it appears some pressure is required to press on the rubber seal.
I’m not understanding your question completely. You asked will it work with no mains connected. Are you asking if it will still work with the water supply not connected? If so, the answer is no.
@morganinspectionservices3840 Thanks for replying. I live in a flat, my toilet cistern seems to be fed from a low pressure header tank (head 0.5-1 m). I installed a new replacement fill valve (not a fluid master) as the cistern was overflowing but now it's filling very slowly by drips (1 hr+! ). By removing the fill valve the water flows quite well out of the half inch feed pipe notwithstanding the low pressure. So I suspect the new fill valve is drastically restricting the pressure. I was asking you if the valve you so beautifully described would likewise reduce the pressure or could you advise another type of valve filler valve ?
Seriously, I had NO expectation that this would turn out to be as interesting and sophisticated a video as it is. Thank you!
Thanks so much for the feedback. Glad you enjoyed it. I hope many others do as well.
Awesome video. I always wondered how that small metal rod made that valve turn on and off. Amazing!
Thanks so much for your feedback, Dennis.

Thanks for watching! Thanks for the feedback. I’ll consider doing one on the other style (once I learn how it works).
Great presentation. I have used these for years and had no idea of the details ...👍
Thanks

I will have to do some research. I do not know what spiral piece you are referring to.

When you say you replaced the entire valve unit, are you talking the seal and the stem, or are you talking the entire fill valve?
