How to Adjust the Flush Water Level on a Modern Toilet System

This is a simple and basic guide on how to adjust the flush water level on a new modern toilet. This is for toilets without the traditional ball and valve system which are on the older models. Often, the water level will be set quite low, which doesn't give a particularly good flushing action. Or if you are on a water meter and are looking to save money you can set this as low as possible.

Probably the simplest and best video on sorting out an overflowing issue. Nice one mate.

Best demonstration I've seen, just right words and perfect camera angle, without all the blabber of other videos. Great work! You saved my water bill!

Brilliant. My cistern fittings look exactly like this so, aside from flicking the switch, which was far more difficult that I expected (I bent my nail and it hurt) - this was very straightforward and helpful. Thanks!

Straight to the point. Wasted 15 mins on other stupid videos. Thanks a lot.

The best tutorial I've seen about this. Short, to the point, without having to hear a lot of nosense. Thank you, thank you, thank you! Now all I need to know is how to make the tank fill up as quickly as yours : )

Thank you! I just fixed my toilet because you were kind enough to make this video. God bless you.

Thanks for making your video -- it got me going down the right path even though my fill valve assembly was a bit different. I bought a HB60000 universal Fill Valve Assembly (black and white plastic) to replace the fill valve in my Jacuzzi Perfecta toilet (blue float and top of float valve cap is blue; rest is white). For both models, there's a small L-shaped square of plastic (red for Jacuzzi, blue for HB60000) which locks the upper shaft and lower shaft together. It sticks out perpendicular to the shaft, and the other half runs parallel to the upper shaft and under the upper shaft. Push down on the tab to unlock the shafts from each other -- it might be 1 or 2 clicks or it might just come all the way out. That frees the top shaft to rotate on the lower shaft on which it sits. Rotate top shaft (which has the float attached) counterclockwise which unlocks or frees the upper shaft from the lower shaft, then move upper shaft up and down on the lower shaft to adjust the height of the upper shaft and its attached float (which adjusts the water level). For me, the tab came all the way out although I think I could have left it in place instead of removing it. It's best to do this adjustment of the float level and upper shaft with an empty tank (turn off water to toilet and flush toilet first) or before you install the new float valve assembly because that float is really strong and once you unlock the shafts from each other, the float with push the upper shaft up strongly and quickly and you have to fight it to adjust it to the level you want. Also best to adjust the water level with the assembly out of the tank since it's hard to see and get your hands into the tanks to do this. Anyway, once the upper shaft and float are at the right height for the water level you want, rotate upper shaft clockwise to lock it onto lower shaft. Then put the tab of plastic back in (or if it didn't come out then just move it back upward into place with one or two clicks). Hope that helps someone since I think my float valve assembly design and model were different than the one in this video.

Thank you so much for this very informative tutorial sir. I just fix my overflowing problem. It helps me save money by not buying new apparatus and no more overflowing water bill 😂. my floater hit the flush valve so close that it doesn't even go up when full so it keeps on over flowing. I just pull back the floater so that it won't touch the flush valve and problem solved. Thank you so much for the idea 💡..., ☺️

tnx brother....i faced problem at least 2 months, after watch this videos my problem was solved.

The mechanism on the fill cylinder was very good advice as other videos didn't mention it. Well done and thanks.

I'm amazed to see so many positive comments about this filler, which to my mind is very close to being absolute rubbish. The lock switch is so difficult to shift you need a screwdriver, which of course you can't manage when the thing is installed. Despite following the video, mine continues to keep filling, even after it has supposedly filled and shut the valve off, wasting gallons of water. I deeply regret buying a "cheap" WC from B&Q.

What an absolute champion my toilet flushes like the rapids rather than a trickling stream. Thank you 👏

[mattfarahsmillionmilelexus]

Great tip, that switch in the back of the fill cylinder was the magic bullet that the other videos missed on.

My syphon was letting water b into the toilet pan, it was a new toilet. Then I had a thought, if the water level in my cistern was just not high enough, the force acting on the seal wouldnt be great enough for it to seal. I used your video to increase the volume of water in my cistern, thus increasing the weight on the syphon rubber sealing valve and it fixed my leaking syphon. Thanks

thanks for this, the guy who fixed our toilet put the water level way too low and the flush wasn't good enough but i've improved it a bit now.

[mithleshgovil]

Awesome demonstrtion. I fixed mine by simply puting the tube inside tank back to where it needed to be. Did not even need a new apparatus. Thank you

[joaquintall]

Didn't work for me :-< Ours does have one of these BUT there is NO "little switch" that allows the float to free itself. There are no "ribs" or "ridges" on the vertical filler pipe to grab the float and move it up and down. Still works, but...

[Dizzy]

Good video. Exactly the same set up that we have. Found the clip but cannot get it to move at all. Does it push in first or what??
Frustrating as Im sure this would fix the problem if I could get it to move!

[nickrobinson]

Very practical tutorial. Just what I needed to know. Thanks

THANK YOU FOR MAKING THIS VIDEO. IT REALLY HELP ME TO MY TOILET. THANK YOU 😍
