Toilet cistern won’t stop running. EASY FIX!!

The toilet cistern kept filling with water. How to changed the ball cock washer/diaphragm.

[@NGTV600]

Had watched other videos which only explained in part, this video helped me finally solve my problem with water continuing to run and it was down to not lining up the marks when replacing the washer! Thanks so much! Saved me paying out ££££s for what was a simple fix!

[@dennisbennett7064]

Thanks so much for this, I did exactly the same as you. I replaced the rubber fitted everything back together and yes it still leaked. There are 2 notches to align inner and outer. If you don’t get them both aligned properly then it will still leak. Thanks again.

[@patrickgannon8190]

Thank you, that little tip to get the rubber aligned at the top has made all the difference, now at last the water has shut off....and for good as I was about to call out a plumber...!!

[@MrRobimike]

Great tip it would not stop filling for me until I saw this video and comment. Working perfectly now

[@clairewheatley6827]

Mine was filling very very slowly I replaced the rubber seal and now it won't stop filling 😂 help! Fitted old one and was slowly filling so at least I knew it wasn't the actual whole unit. Finally after many attempts I got it to work!

[@starmole5000]

I literally had this exact same problem only a few days ago. Had the diaphragm replaced and then it started overfilling. The issue for mine was the top bit. If you look at the bit where there's a small hole and what looks like a rubber flange, press your finger down on the plastic part in the center of the hole. If it stops overfilling then you have the same issue I did. I fixed it by placing 3 very small washers under the lip of the white hole so it held the flange and the little plastic bit down, essentially simulating constant pressure downwards, and it works now!

[@davesutton2381]

I have exactly the same issue currently 🤣🤣

[@KenR208]

Good to see someone work on the inlet valve instead of the flush, and show us what happens when it's not fitted properly, most helpful,

[@shelleyrichardson2070]

Thankyou so much you are gold 😊

[@shonaflaherty384]

thank you!!! from all of us too broke to afford a plumber

[@tonykeary1270]

Perfect that little rubber thing was what was wrong with mine. Nearly fully degraded

[@raghavendran7154]

This exactly worked for me. Saved my money. Thanks a lot for educating us sir

[@nanumanu13]

The little nozzle was disconnected. Your video helped me find and fix it. Thanks a lot! 🤑

[@Offline1988]

You saved my day, thank you so much! Basically the water tank was running constantly so I bought a spare part , when I got home I realised that was the wrong part, and was already Saturday, all shops are shut, on Sunday are not working, and the most issue is that I got one valve for both water tank and the bathroom sink, so shutting the water tank pipe valve would mean shutting the entire water in my bathroom. Found that the washer had some debris cleared it and it worked! Thank u so much sir! 🙏

[@angelahart6218]

I replaced the rubber, its all in correctly and put it in and out multiple times now but its still overfkowing no matter how many times i take it out and adjust it. Losing the will to live!

[@debnairwilson6052]

I'm off to B&Q with a spring in my step! Thank you for this!

[@davemcdave2169]

Amazing big man. Thankyou. Short trip to screwfix and all sorted. You should set up 'buy me a coffee' as it's always good to give a small bit of cash for cracking advice.

[@pdunleavy1982]

I’ll look into it. I think there’s a “Thanks” button on KZbin that lets you give tips. Somebody gave me one a few months ago. Glad the video helped.

[@rhys1944]

Can anyone help please, the part that the button screws into has dropped further into the system and I can't see it, I need to replace it but don't know what it's called or where to find it

[@cryptombt5880]

Thank you so much mate. This is the exact one I have. Time to order a new part

[@CS-ms8pj]

Thank you so much.I replaced the valve but now cistern is over filling. Think I need to adjust the float level but unsure how 😖

[@pdunleavy1982]

Usually you can just twist the screw that the float is attached to.

[@CS-ms8pj]

⁠@@pdunleavy1982Yes, I found ‘turn to left to left’ to lower water level but didn’t make any diff

[@usy37]

thnx man its really help me 👍 i got this rubber cheaper 3£

[@richardvannjones9632]

Thank you for taking the time to post this. It worked a charm! (after I managed to line up the valve notches properly. Glad I wasn't on hourly rates...)

[@pdunleavy1982]

Glad it helped

God bless you! Mine didn’t even need replacing just reseating in place

[@mixaylo1981]

Thanks . I sort the problem 👍❤️❤️👌👌

[@ellevee9523]

My toilet hasn't got one of those screws to turn the water off so i turned off the stopcock but the cistern won't stop filling up??

[@pdunleavy1982]

@@ellevee9523 I’d say you haven’t turned the correct stopcock off then. Or it hadn’t closed all the way

[@Gemrh86]

Hi, Thank you so much for this video. My cistern was taking ages to fill up. Just check and the washer was in a bad way. Just ordered another one. I have noticed as well that there was also a constant flow of water running into the bowl - would this be a related problem or it is something different? If so, what would be the solution? Would I have to change the rubber or a part at the bottom too?

[@pdunleavy1982]

I think both problems should be solved with the new washer.

[@Gemrh86]

Thank you so much for replying. Fingers crossed it does 🙂

[@adamrandall6399]

Appreciate you for making this video. 🙏🏻

[@stevengower9982]

What is the top bit of the filler value, the little white thing that drops into the hole when the toilet stops filling (see it drops at 7.51 in this vid). This is what won't drop properly on my toilet. Any idea how to fix? Is it another rubber seal or similar?

[@jonos138]

I've had mine to bits the same. The rubber washer is fine and it still F**** leaks. Worst design ever for a cistern. I have 2 of these in my house and they are both shite. Both of them keep playing up and running water. Bring back the metal valves with plastic float. Rarely was there a problem with those. These crappy plastic fittings don't work 5 min without having to fiddle with them!

[@davecustance3423]

Thanks for vid and thanks for leaving the section in that showed you had to try again … that helped me a lot because I had exactly the same problem and realised the washer wasn’t quite seated properly … well done v helpful … and also the toilet internal parts were identical … plus helpful Amazon link page cheers dave

[@charlottethomas5677]

Doing mine. It's easier if you take the plastic arm away from the round plastic thread. When you go to put the thread back on you can align the notch perfectly and the plastic arm doesn't get in the way.

[@wozzywaterfield5913]

I’ve changed the rubber but it’s still running after the cistern is full but it stops after about 30-40 seconds ? It does fill up fast now and not slow.

[@clairemaule8747]

Thanks for this video, it's exactly what I needed to help me to stop my toilet cistern overfilling :)

[@KieranJB]

Did I skip ahead, miss the part where he turns the water pipe off, and spray water all over my bathroom? Maybe.

[@pdunleavy1982]

I’m pretty sure that part was at the beginning.

[@salfetka]

I will have to try this i've got the same issue with the same toilet mechanism. Thanks mate

[@marcjoyce765]

Thank you, this was so helpful. I have 1 question though; i twisted the nob to make the float lower, however that doesnt seem to stop the water. It continues to fill the cistern until approx 5ml below the overflow pipe. Any tips or should i just apply the 'dont fix whats not broken' addage?

[@pdunleavy1982]

I think I would leave alone. Or keep adjusting the float lower. Trial and error.

[@CS-ms8pj]

Please clarify what you did ‘wrong’ as I clearly have? I have done it twice now, taking care to match the notches & fail to see what the issue is why it won’t stop filling/shut off

[@pdunleavy1982]

I didn’t line the notch up first time. When you pull it up with your finger, does it stop the water?

[@michaeljawaharbravuri7665]

Thank you so much. Appreciate making this video. God bless you. I fixed mine with £3.5.

You any idea how yo remove that middle part? I've a problem I'm trying to fix and need to remove that flapper bit

[@pdunleavy1982]

@@megc18 there usually 2 nuts underneath that bolt it to the bottom part of the toilet. Undo those and undo the water pipe and the top part should lift off. Then there’s a big plastic nut holding the middle part on. There might be some crews holding it to the wall as well.

[@megc18]

@pdunleavy1982 I appreciate the reply mate. I can't do that though, I have alot of hidden things on the toilet. Cause it's fairly new most of the pipework ect is hidden. Can't even isolate the toilet. Need to turn off the water for the whole house when trying to sort it. Thanks though

[@pdunleavy1982]

@@megc18 that’s the problem with hidden pipework

[@megc18]

@pdunleavy1982 I'm sure I can get that flush valve out by unclipping it or something but I'm far too cautious I break it. Yeah the hidden features are a nightmare

[@philtucker1224]

If you are talking about the central tower, it just turns slightly anti clockwise to un clip it from the base.

[@darrenlee8118]

I changed my Diaphragm Washer but still finding the water still flowing slightly in the basin which makes the system every so often fill back up which makes a noise like there's a air block

[@pdunleavy1982]

Have you double checked to make sure the diagram is sitting in there properly?

[@olliemoffat4025]

Having this problem too. But the thing you unscrewed by hand on the left is tight and win't budge. Don't want to force it incase i break it. Any ideas? Please and thank you

[@pdunleavy1982]

You might need a bit of help with a pair of grips. Just don’t go crazy. Can’t always be done by hand.

[@CS-ms8pj]

I had same prob, didn’t want to use metal on plastic. I gently tapped all around where I could & it unscrewed after a while

[@peaksandpioneers-uv5nz]

Hi there, we’ve got a similar cistern as in this video. The cylinder in the middle bit won’t slide down enough to close the gap and stop the water from running. Have you any tips on fixing this?

That’s the problem I am currently having with my daughter’s cistern. (Did you eventually get it to seal?)

[@KathleenRamsay-s4v]

Hi, my toilet cistern was taking ages to fill up so I replaced the rubber seal as shown on this video. It worked great for about a week but now the water won’t stop running even when the cistern is full. I can’t get a plumber to come out to look at it. Do you have any ideas what it might be? Many thanks

[@pdunleavy1982]

I would check the rubber again. Maybe it wasn’t sitting right and it’s worn a hole in it again.

[@ilariafrau8018]

Thank you! You are a star ✨

[@keithmonk4503]

Not mentioned in these videos is there is a rubber inset in the lever arm circa 6mm dia. Not easy to see as white the same as the lever. This can be indented to such an extent it cannot form an air tight seal to the little hole in the end of the plastic piece he took out. The rubber can be pushed out from the rear turned round and reinserted to expose a fresh smooth surface. I replaced the sealed in the video but still had a problem. Turned round the seal in the lever arm solved the problem.

[@tonytraveller7218]

Im having the same problem, I do not see a rubber inset at all on the lever arm and cant find the part at all? I replaced the seal as in the vid (flow valve) but water is still jetting out of the little hole in the lever arm? And the toilet does not stop filling
