How to fix Caroma Uniset toilet leak?

Caroma Uniset.jpg I’ve replaced both the inlet and outlet washers on my Caroma Uniset yet it leaks a lot from the bottom of the grey tube on the right into the pan, even when the tap is turned off at the wall.

When I lift the rocker arm up high, placing pressure downward, where the new inlet washer now is, the leak stops.

Is this somehow the problem? Can you help with my next step? Thanks gurus!

Apologies for the skewed pic, can't seem to right it...

Hello @Easy1520

Getting a matching seating washer for the traditional flushing valve of your Caroma toilet can be a challenge sometimes. In my experience the Kinetic Seating Washers - 2 Pack (the red one) is a much better match to the Caroma set. The use of dish washing soap is an excellent technique to center the washer, but I recommend using a massaging movement as you go around the seal. Your goal is to center the washer to the seat, take your time and don't rush trying to center the seating washer. It can get a bit wearisome but be patient, the washer will center itself and will seal the toilet valve properly.

If you need further assistance, please let us know.

Hi @Easy1520,

A warm welcome to the Bunnings Workshop community and thank you for your question.

Can I trouble you to remove the outlet valve and show us how the washer at the base of it is sitting?

Considering that the water is leaking into the pan and when you apply pressure to the rocker arm it stops, it seems likely that the outlet washer is the culprit.

It sounds like it is not seated correctly or there is some debris that is preventing it from sealing correctly. If you are confident it is the correct size, I'd suggest you inspect the outlet seal and the hole at the bottom of the cistern and remove any debris you find.

Allow me to tag @Jewelleryrescue and @Dave-1 to see if they have any ideas on what to do from here.

Let me know how you go.

Managed to move the washer into a better position using detergent and noticed how it fits better under the clear plastic now. Still having the same leaking problem though. Will persevere....Arggh! lol 🙂

Thanks Jacob 🙂

Looks like I've failed outlet washer replacement 101. The area beneath is clean and free of debris. Any tips on getting this little devil in place properly? It seems to have a mind of its own! I watched some youtube vids and some suggest using liquid detergent.

Thanks for your help.

Cheers 🙂

Evening @Easy1520

Mmmmm when I have had a similar leak and also when I have had washers fail on the top I have ended up changeing over the whole unit in the end 😕 Its happened twice now where the washer has perished and even if I find a washer that suits it just dosnt seem to work.

I do know that Bunnings stock a universal one. Which is what I have used to eventually solve my problem. Id give it a few more trys but for the time and effort verse getting it fixed and multiple trips back and fourth 😕 Yeah.... I know the frustration well.

Hi @Easy1520,

It's in the right place, but your washer is too small. The washer should cover the entire white section at the base of the valve.

Can you advise what the diameter of the white plastic piece is?

I suspect this FIX-A-LOO Seating Washer - Suits Caroma Duoflo And Thunderflush is what you should be using.

Let me know what you think.

Thanks Jacob,

I've used the "FixALoo Seating Washer - Suits Caroma and Dux". Its dimensions are close to the Duoflo. But seems not close enough.

Sealing Washers:

Suits Caroma and Dux: Washer Dimensions: Outside Diameter: 62mm, Inside diameter: 24mm, Washer thickness: 1.70mm.

Suits Caroma Duoflo : Washer Dimensions: Outside Diameter: 66mm, Inside diameter: 25mm, Washer thickness: 1.60mm

I'm sure you're right though, so will get the one you recommend and see how I go.

Thanks very much for your help. Very much appreciated!

The pic is a bit misleading. The diameter of the white plastic is about 78mm.

Cheers to ya 🙂

An update on all your good advice is that the Kinetic washer has worked. Yay, hoorah and thanks again!

I think the one recommended by @JacobZ will also likely work so I bought both and will keep it as a spare when needed for the second cistern in the house.

The only minor problem is that I can't replace the cistern top fully as it pushes down on the rocker arm at the float end and lets water into the pan. I've played around with it to no avail so will just let it sit there, half locked on. At least it works.
