Potex water cistern flushing system

[Neutralsg]

Thank you for sharing . Although it may be an old thread, it is useful for me now since I encounter similar problem recently.

Have a nice day!

This follow up post is to contribute towards this article for members who may have similar problem since I managed to fix the leakage using a compatible part since the original part is no longer in production.
1st thing to note is the model no. of the potex cistern. Mine is a TM311R. After purchasing the part, modification is required to fit the compatible part to the system. Even the flush button which comes with the new part as part of the package is different although the original button may be used.
Photos of the original and compatible parts cannot be uploaded for now because I do not know how to upload the image in this new design of MCF since the image button only has a url column without a browse button which I usually find to upload a file or image from my computer or thumbdrive.
Anyway, parts are available at Tiong Yeong Hardware.

Cheers!

A white plastic screw is on the top of the lid,use a coin to open.

Advisable to check the date of the post before you specifically reply to it otherwise you may be relying to an obsolete question and waste unnecessary effort.

Can try look for flush valve assembly and DIY replacement. The flush valve comes in diameters and length/height, although some height adjustment provided. Bring the flush valve along to compare with stocks at the shop. Not sure if I still got spare around.

Seems it is now possible to upload the photos which I did not manage to in above post. The new part from Tiong Yeong costs iirc was about $10-15 per set. They were the one who recommended me the substituted part. The only modification I need to do was sawing off the length of the new part to fit into existing cistern. The original push button was used instead of the new one which requires adjustment.

Hope this helps those who uses the same Potex model i.e. TM311R.

I believe all new and past hdb owner have potex toilet and flushing system installed.If your water keep on flowing from tank to toilet bowl then your dounut shape gasket below the plunger must have spoiled. I manage to found silicone type replacement for potex brand at this place and walaa it stop flowing endlessly.
I found mine at rivervale plaze near punggol a hardware shop called hardware 88 trading, i can't believe i can find the exact fix.Anyone thinking of changing without buying a whole cistern can consider.Homefix also have silicone gasket but not suitable for potex cistern as it was too thin and single layer.

Another type of leak is the 50cent size washer inside the ball float arm that will cause the refill to flow non stop easy to buy and fix too.

.

potex a sanitary brand from malaysia installed on new hbd flats a decade ago.i help you hope next time you guys can help me back too.
