Push Button Cistern Cable Stuck, Can’t Access Flush Valve - Help!

[dilalio]

Probably started leaking at the flush cone because you've been disturbing things - always happens!

While you have all that exposed, I'd put a support under the flexible pan connector as these have a tendancy to droop over time, fill with crap and then pull off the back of the spigot!

Remove whole flush valve with cable assembly. Valve is a bayonet fit.

The cable end to valve is a clip in fit, but the clips can break fairly easily *I have the T shirt..

https://www.siamp.co.uk/optima-50/ may help with all that?

Flush cone should be easy to sort and may just need a remove, clean and some silicone grease to refit and push back in place?

 

[dilalio]

seems to be fitted just with putty/mait.

Nothing wrong with that used on a flush cone.

Thanks again, all - I’ll order new valves and try to get them out via the opening, rather than have to remove both the cabinets/units. It’s really only access that’s the issue.

I’ll have a look at fitting a new flush cone.

They lose their flexibility and rubberisation and therefore watertightness. Slightest disturbance and they'll leak.

Usually limescale issue in hard water areas.

I see you managed to slide back panel up and out

Put a smear of LS-X around the flush cone, it was only slightly, possibly, damp when adjusted.

Bought a new Thomas Dudley flush valve, but the cable was too short, so, upon further investigation, this was the button issue - not sure if it was supposed to have a terminal on the end of the wire:

Crimp a bootlace ferrule on to it?

If I had one… Ordered a new one from Amazon, was getting limescaled and sticky anyway.

This is testing my patience - not wanting to fix what isn’t broken, I’ve replaced the diaphragm washer on the Siamp fill valve (cleaned the existing one, but it was still sometimes slow to fill). Didn’t touch or change anything else, but now the cistern will sometimes continue to fill until it goes down the flush overflow, even though the float/tray has popped up and there doesn’t appear to be anything flowing via the diaphragm washer. Everything looks fine, the washer is seated correctly, changing the float/rod height doesn’t make any difference. Can water enter the cistern aside from via where the diaphragm washer assembly is?

You're not alone!

I've spent hundreds of hours, over the years, feckin about with inlet valve diapghrams!

With life being too short, water usage now metered and limescale a bastard to remove from the pan... I try replacement once, if it's a match to what I keep on the van, and then I change the whole inlet valve to a fluidmaster or skylo.

If I don't have one, I'll go to merchants and get one. Not economical to keep trying to stop a £3 washer from letting by.

Personally, I don't think the rubber is as good a quality as it used to be!

 

[HERTS P&D]

As above, I always carry fluidmaster fill and flush valves in the van and always recommend all the cistern internals are replaced.

Not just me then! Thanks all for the advice, it seemed to be behaving so I’ve siliconed everything back together.

 

[dilalio]

so I’ve siliconed everything back together.

Not overly so, I hope!
