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.

[@cecilreyes5583]

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!

[@ah7910]

What??? It was in total silence.

[@ainslieberrafella]

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!

[@marshascholl4226]

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

[@susannafranco510]

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 : )

[@Ferrettherrett]

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

[@rogerslack6595]

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

[@jasson828]

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 💡..., ☺️

[@nahidulislam2276]

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

[@markandjuliemears3745]

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.

[@HUYI1]

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.

[@mattfarahsmillionmilelexus]

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

[@KindCountsDeb3773]

Never heard of it. I bought a house with the Project Source already in.

[@jun_suzuki42]

Just wanna let you know that your video has been absolutely helpful!

[@garywateridge]

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

[@mithleshgovil4092]

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

[@Dizzy7878]

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!

[@TheForever1990]

Easy cleanup , came as described fast. Great product

[@jerryd8107]

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.

[@mushtaqmian6538]

Thanks a lot for UR nice presentation,I really enjoyed and fix the flushing tank easily.

[@fx802]

Thanks!! Can not stand these water savers that are not water savers!!

[@christoph4951]

You need to flush twice just to get it down lol

[@sustainablelivingnl773]

I just bought a toilet and I have the same problem. It took me some time to figure out the problem. Unfortunately the over flow tube is cut too short which prevents me from adding more water. I think I can buy an over flow tube extender but this is crazy. The toilets should be designed to flush well with less water and if that can’t be done then go back to the way it was before. There is no water saved if that toilet has to be flushed 2 or 3 times to flush everything away.

[@RATANKUMARRateria]

Adjustment details are fine...Thanks.. Can it be dismantled completely for cleaning inside out and then refitted ???

[@sudathliyanage7006]

Yeaaah. It was much helpful for me also. Thanks for sharing. Wish you all the best.

[@Andy-fr2im]

best video I have seen so far - I have a problem which means that the water fills and it goes down the overflow pipe - the little plastic bag that surrounds the plastic part that is next to the stop cock is ripped and I am not sure if that might be the reason some how. So far I have taken off the post to get to the rubber seal but that seems to be ok,. The water stops rushing in fast when refilling but it is still steadily filllnig until it reaches the top of the overflow. I think I need buy a new unit or call a plumber - I am going to check rubber washer one more time to make sure it is working but it seemed ok

[@securoid]

Thank you so much for your video. It was a great help. Tank was overflowing like hell. Thanks a lot.

I could not find a switch and turning the screw did nothing and this is a new valve.

[@rufinocabang6099]

Same here. Does nothing with the newer-style toilet my landlord installed. The water level is low and stays low. And a plumber told me it's just made that way (which makes the screw-thing it has very confusing). Argh.

[@pat2633]

There must have been a change in design it seems your toilet has a slight change in the float also i noticed you don't have an overflow tube to prevent tank from over filling For those of you that have one you will have to extend yours or cap it off However if you cap it off you run the risk of having water run all over your floor if the shutoff float ever sticks

[@TheKingofHowTos_TKHT]

CHEERS MATE!! I will try this with my very similar design Tuscany dual push-button... These are nice looking toilets with slow/quiet close seats, but the flushing mechanism has cost me THOUSANDS of dollars each time that I have to call the plumber to unclog my drains in my multi-units after my tenants clogged it... HEY GUYS, I have an easy idea on how to fix that overflow issue if you would like to get even more water in... Try the following, which I already know would work as a SMART/DEEP/THINKER/INNOVATOR as I... Solution: Purchase a compression-type rubber fitting with rings that allow you to attach via fasteners... Now attach a 1" (I am guessing that the over-flow is around 1"-2" pipe, so get one compression fitting just slightly wider to go around the over-flow pipe)... Tighten up snugly... VIOLA! You have successfully extended the overflow by another 4-6 inches. So now, you can adjust the height of your water even higher up to around 2"-3" higher or 8L-9L (this also depends on how high the mechanism would allow for you to adjust)... VIOLA! You should now have an even more stronger flush after this mod, assuming that the mechanism will allow you to adjust the height even higher... I will try this idea, and I should make a video about it one of these days... Good luck mates and tell me how this idea work (it should/will work as I am rather confident, except the mechanism doesn't allow you to adjust that high as this is the only restriction)....

[@rssagoo5780]

Thank you so much for the video after flushing I would hear the noise as it was trying to still fill up as the float was not popping up. After putting the float down it now pops right back up when its full thank you so much .....!

[@Shona632]

Thanks for the video. The problem I have is that the water does not reach the full water line because the float rises to the top too soon & then the water is cut off. I cannot adjust the float screw to let more water into the cistern because it has been adjusted as far as it can go. The design of the screw is terrible because the thread stops 3 3rds of the way up. Which means that the thread does not go the full length of the screw so it cannot be adjusted anymore than that. So even on full flush the toilet does not flush the waste away completely & so we have to flush twice. (They call it a water saving model but it doesn't save water if you have to flush twice!) We have had this issue ever since we had the new toilet installed less than a year ago & I miss the old one which was probably as old as the house (built in 1952!) They dont make em like they use too. The only solution I can think of is to go back to the plumber &/or find a screw with thread on the complete length so I can adjust the water level. I dont know if there is one available as a replacement. It's a Levivi Marbella toilet from Plumbing World NZ. Do you have any good suggestions please?

[@TheAnnieSisters]

Wow same issues here! I have found some relief with letting go of my super plush fancy ply paper and finding the fastest disintegrating t.p roll we could handle. We only have to double flush once a week now.

[@sylviawofford4216]

I turned the water off and used the tip of the screw driver to push it in to the right. You can't see how he did it in the video but I slowed it down several times and noticed that it looked pushed in. I couldn't do it with my hands like he did so I gently used the tip of my screwdriver.

[@RATANKUMARRateria]

Can this be dismantled completely to clean the insides of the Tube with some cleaning agent? The quality of water supply in our city is very bad and the valves gets chocked with calcification & iron...???

[@joaquintall5180]

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...

[@OCC_Plumbing_and_Restorations]

This is an R&T fill valve that is from China. They can be found in ProFlo, Glacier Bay, Niza Pro, and a few others.

[@RJ-gg9xp]

Owen Cowan do you happen to know where to get it? I need to replace this whole thing and am struggling to find replacements! Thanks

[@OCC_Plumbing_and_Restorations]

@@RJ-gg9xp You can find it on a website called AliExpress or at a plumbing store called Ferguson. You do not need that exact fill valve though, you can just get a Fluidmaster, korky, or any universal fill valve.

[@woojinjoo241]

would you turn the screw for the fill valve clockwise (as in this video) to increase the flush volume? Typically most online advice recommends counter clock wise to increase the flush volume. Is this particular fill valve different than the standard ones?

[@OurBackGarden]

Great video. Helped me understand the valve more but still one huge problem, it’s not long enough and cuts off to soon which makes my toilet difficult to flush because it’s just not full enough with water! Do they make longer ones?!

[@Dragon-Slay3r]

Thanks for that

[@rpmorrisjr]

Yea it actually sucks as a toilet. It’s like going to the bathroom in a drywall bucket. No. There’s no way to increase the water level. Nothing demonstrated on this video accomplishes anything at all.

[@RJ-gg9xp]

Hi - do you know where to find the replacement parts? This is the exact set up as my toilet and I need to replace the dual flush valve next to it as well. The part you mention is leaking from the top so I’m thinking it needs a replacement! Thanks

[@richardtran2358]

Thank you.

[@subterraneansecret]

Glad the video helped you out.

[@Magpiehills]

As shown, I adjusted the float housing so it was further up and then adjusted the float by twisting the screw. At first, it seemed to work as the water level in the bowl went up to a good level. However, then water in the bowl slowly flowed out until the water level was low again! Is there anything else I can do please?

[@Dragon-Slay3r]

Was I even working there then? Lol

[@KindCountsDeb3773]

Some people say to screw the rod, Nothing about the "switch" on the back. My flushing is Not dual. Would that make a difference? I just want my bowl water to raise, but when it did, it also went into the filling tube. I will keep working at it. Maybe my Project Sources toilet is a piece of crap, No pun intended. lol. Thanks.

[@padmavathi1341]

Thanks, it worked for me…problem fixed

[@GiGi-nm6pw]

To me it looked like nothing changed after the adjustment. Same water level in tank, same water sound. Maybe you should have switched camera angles to show the flush difference in the bowl itself.

[@chessguru900]

How to increase the water flow into the tank could have been mentioned.

[@ddad6011]

I discovered another solution. If anyone find difficult to move the button as myself then better to tie some thing light heavy thing with the floater then it will come more water into the system to lift the floater but not too heavy thing otherwise water never stop to come in. It's work for me as couldn't move the button.

[@stephenhart6158]

got it, what are the graduation marks 1-40 on the outlet used for, got a situation where i have water in the cystern and the inlet tap is shut - push the button and the dump button works for the required time i want it, but if i open the water supply and then push the dump button water continues to run. almost a new unit, doesn't seem to be any debris around the seal rubber looks ok?

[@Asl6uk]

We had a great toilet, until we had a new suite installed. It was a Rolls Royce flush and a pleasure to use, much better than the crap they install now.

[@SpencerGordon]

My Galba toilet is only 2 years old. I noticed the other day the fill valve was slowly running even after it reached the fill line. I lowered the float to lower the fill line BUT even with the float in the cut off position the valve is still allowing water to slowly run water. My guess is the fill valve has gone bad. Any other adjustments to try before I order a new fill valve?

[@vpatrickd]

Do you know how to repair if the water in the bowl (not tank) is too low? Which of those parts in the tank are responsible? Thanks.

[@Jimsathome]

The water level in the bowl is a result of the geometry of the trap, and there is no way to adjust it once the toilet is manufactured. Some low flush units don't have much of a water surface area, and the Bowl soils all the time. This seems especially true with a Caroma toilet - which we just installed. Our Pearl unit is a bit better, and an American Standard unit is the best we have in the family. We can't even return the Caroma as it only has a 14 day return at the distributor. We bought it before we renovated the Bathroom - and it took us a couple months before installing the toilet.

[@OCC_Plumbing_and_Restorations]

The fill valve. Connect the rubber hose to the overflow tube so that it brings water to the bowl.

[@mdafzalkhan8374]

I want solution for when i push the button of flash tank. Water flow didn't stop till the water tank empty. I want to pass limited water.

[@JJ-yh9kf]

I think you would adjust the float the opposite of what this video shows,so the float is lower and shuts off water faster.
