Triton Pressure Compensating Shower - cold?

[rjs123]

We replaced our bathroom suite last week but kept the existing shower as it was only installed two years ago when we had our combi boiler fitted.

When using it now, it runs hot for a while then goes very cold, then warm. My husband removed two valves (which we thought were just connectors) and put isolation valves on them which are located in the loft/attic.

Could this have made a difference? Were the original valves special ones?? Or have we messed something up when putting it all back together?

Any advice would be great, I don't like cold showers!

It's cycling on the tco
doubt it's anything to do with the isolation valves fitted more likely scale has shifted when you isolated the mains to fit these valves.
check the valves are fully open and check the inlet filter first for scale etc.

what model triton is it ?

Thanks for your reply. What do you mean about the tco?

I can't find a model number, it just says pressure compensating on the front. It's just a round mixer fitted to the wall with the hot & cold coming into it.

This is the best resemblance I can find, http://www.showermania.co.uk/prodimages/Pressure Compensating wc.jpg

sorry didn't read it properley.
yes the triton pressure compensating mixer valve.

sounds like it's making the boiler cycle on/off so giving hot/cold flow.
watch the boiler when this happens see if it go's on/off.

have you a pic of the fittings you removed ?
fitting isolation valves shouldn't really affect the shower
where they full bore or restricted bore valves you fitted ?
