Shower not turning off when switched off

[Kcoz15]

I have a triton t90sr it's working fine apart from when switched off it continues to run water at a slower speed for about 5 mins . Also I have turned the shower to cold only setting and water runs at a slower speed for even longer after it has been turned off.it will only turn off if it is switched on to heat water again and turned off. I have turned off electricity and water still flows. Hope that makes sense . Any ideas please ?

Solenoid valve ,probably needs replacing.

Ok does that mean I have to change the whole valve or just the solenoid ?

 

[terryplumb]

The solenoid . It's what opens or closes the water flow into the shower.

Usually just the solenoid - about £10 not sure in Ireland.

No!!
The solenoid, when powered, opens the solenoid's VALVE. The solenoid is just a coil of wire. When the power is removed the valve shuts, therefore it cannot be the solenoid. You must replace the valve, though it's usually only sold with the solenoid attached.

Sorry for the confusion ,I was not referring to just the electro magnet , as meldrew mate quite rightly points out ,it's the solenoid valve. It's the valve that the solenoid operates . The plastic assembly that the coil attatches to.

Ok so I need to replace the whole thing and that would probably mean a plumber ?

That depends on your skill set.
You only need spanners and screwdrivers in the way of tools.

So am I right in saying I need to replace the whole of number 5 here ?
