I was nervous about replacing this myself until you demonstrated that it was just like a bayonet lightbulb. Job successful. Thank you.

[@EM-yk1dw]

Thank you for this. I changed my flush valve and the half flush works again

Would be great if you were to have a closer view of the bellows in operations & access to remove & replace . The video was all done at a distance . Better camera work would of helped. Mostly it's the bellows that are the issue & scale build up. Although its cheaper to replace the bellows , for peace of mind for the customer & future callbacks its best to replace the while flush valve. The push buttons are quite expensive especially the 2" button & in some cases it's cheaper to purchase a whole replacement cistern which comes complete with all parts as opposed to buying the parts separately.

fixed my problem. Flush working, but very difficult. Cut ends off tubes at all joints, worked great thanks.

Big issue with the pneumatic flush valve is if you have low pressure water supply to the cistern, what can happen is the flush valve let's by when filling as not enough water coming in to fill the cup on the flush valve. If you can't get enough water to come in to the cistern what you can do is make sure the flow restrictor is removed as it sits inside the inlet spigot of the cistern & not inside the fill valve itself. If you still have fliw issues what you can do , is to remove the flush valve seal on the bottom , with a large flat blade screwdriver is to prise out the centre green portion which will expose a spindle, using either 1 or 2 penny washers or some solder wrapped around it . Replace the green button refit the flush valve seal & what that then does is help to hold the seal when filling. You might have tk do 2 or 3 tries at fitting some of the washers as if it's too heavy when you attempt to do a full flush when you let go of the button the valve won't empty the cistern. The manufacturers are aware of this issue although won't admit to it. So don't go thinking it's a faulty unit as what will happen is it will do the exact same thing with the new one. If you can remove the unit altogether & fit a different flush valve as these will give you major problems down the line. Another tip with these cisterns is adjust the water level to about 5 -10mm below the water line. The reason being is when the fillvalve shuts off , being an equilibrium it will take a few seconds to adjust the pressure & shut off. On a hp system this can take the water level above the overflow & in some cases spill out the front of the cistern itself. Again the manufacturers are aware of this but won't admit to it.

Many thanks for the explanation here! Managed to fix my flush (cistern was stuck constantly filling/emptying in a loop). I just cleaned the cables a bit and it's all good now!

Brilliant thank you 👍

I’m so glad you put these videos up for us repressed pedantic types to get inspired to create freely without worrying about every little thing. It’s like opening a window on a stuffy room.

Recently had new cistern installed, the same as the one in your video with the blue access panel, and have water leaking from around the push button, having removed the front panel I can see water in the clear pipe, I thought these blue and clear pipes from push button were for air only, does this indicate a fault? Thanks.

[@paulroff8263]

Between 10 & 15 years old, just needed a descale of the linkages.

[@nickdunnill2514]

Hi I have an issue with mine flushing too aggressively on the main flush cycle. To the point water is spilling out the panand onto the floor. can you reduce the main flush?

[@strummer6642]

I have a single flush button and a dual hose entry. Will work if I just fit one pipe?

[@thomasdudleyplumbing]

Hi, if a single flush button is used it should be connected to the clear tube. The green tube which is for the reduced flush can be disconnected. If you need any further assistance please call our Technical Helpline on 0121 530 7000 option 4. Thank you TYDE

[@dmhhackersdmh3871]

having trouble accessing the flush valve as the inlet float valve system is preventing removal of the flush valve? Can you advise?

[@thomasdudleyplumbing]

It depends on your cistern installation but we’d advise isolating the water supply and then removing the inlet valve first in your case, before then servicing the outlet valve

[@user-po1sx9cl4p]

Very informative but annoying music which makes it difficult to hear the narrative.

[@11982463]

Whats the replacement button code or where do i get it please

[@davelinkson1]

Thanks.. I had a new dual flush cistern installed recently and water has started leaking from the push button when pushed. Just had a look behind the panel and have the blue and clear tubes, I thought they only carried air, could there be a fault with the flush valve? Thankyou.

[@thomasdudleyplumbing]

Hi David… Thank you for leaving your comments on our video. I’m sorry to hear that you are experiencing issues with our product. This is a strange one… As we have never seen this issue before? The product you are referring to is a pneumatic outlet valve and as the description details, the tubes are for air and should not contain water. If installed and connected correctly the tubes and button should have no physical connection to water, so it’s extremely unusual for water to be coming out of the button? I advise to start checking all of your pneumatic connections are secured and in accordance with our installation instructions. If you are still experiencing problems please contact our technical helpline on 01215307000 (option 4) and our product experts will help you resolve any further issues you may have.

[@davelinkson1]

@TYDE thanks for your reply, I have looked at the push button tubes and can see water being sucked along one tube to the flush button when pushed, I can only now think it's a faulty tube connection at the flush valve end or the flush valve itself is faulty, the leak has stopped at the moment and the area is dry,but if it starts again I think I may take out the flush valve to check and have a look at the tube connection and probably remake the connection.. I think the flush valve just twists out of the cistern tank doesn't it? After turning water off..

[@thomasdudleyplumbing]

@@davelinkson1 Hi David. Thank you for replying to us. We’re glad to hear that the issue seems to be resolved. You are correct the flush valve is removed with a ¼ turn. It is possible to re-terminate the tubes without removing the valve. Simply remove the tube, cut off 1cm and re-connect. We are always available to help on 0121 530 7000 Option 4 should you need us again.

Excellent video BUT useless if you need to hear what guy is saying! Even with expensive hearing aids I cannot get past the noise of the music in the background. Why on earth did someone think that was necessary? Note to moderator: I am not the only one with this problem.
