mixer shower question

[kowalski181]

hi
my father in law has passed on an unwanted rada thermoscopic 215-t3 temperature control. it's a big thing with 3 inlets coming off it i believe 1 hot 1 cold and 1 wate, trouble is its only a temperature control theres nothing to actually power it. ive bought an exposed shower kit to go with it but am led to believe that without the valve to control the power it will be useless and that the shower will effectively always be on. can someone educated in plumbing matters please tell me if this is effectively useless?
thanks

Hi. Does it look like this: https://supreme1.sslpowered.com/cgi...ers/Rada_and_Meynell_Showering.txt&item=00001


Never fitted one myself but looks straightforwards.

You need to get hold of a copy of the instructions. http://www.radacontrols.com/onlinecatalog/pdf/1057616_w2_a.pdf and read carefully to answer any questions. If not phone tech support.

Normally cold will go to the right hand side and hot to the left hand side, and the shower hose connects underneath.

When you say nothing to power it - do you need an additional pump? Is your hot water supply from a gravity system, unvented or combi boiler? You

If you have a gravity system (tank in the loft and copper cylinder), the cold must have its own dedicated supply from the header tank feeding nothing else (this connection to be made lower than the outlet for the hot water feed), and the hot water to come from a tapping near the top of the cylinder or a branch off the horizontal pipe coming from the top of the cylinder.

many thanks
yes thats the one, though this particular unit has the control bit in the middle as seen but on the top it has the 3 inlets, rather than on the bottom on that diagram. as far as we can see it only has one control you can move at the front to change the temperature control, nothing to actually turn it on and off. we have bought this Exposed Overhead Single Spray Shower Kit RA Chrome - Deva available at Plumbworld to use as the shower, but what would we use to turn it on and off?
we have a worcester combi condenser boiler
thanks

There is normally a wheel on the mixer itself to turn the water on and off.

Have you checked your boiler is able to provide sufficient water flow and that the mixer has sufficient water flow for the shower fitting you have selected? If not, it will just dribble.

Can you post a pic of your mixer?

thanks again
here are 3 pics of the shower valve thing
yeah plumber checked when pricing job that good water pressure upstairs from boiler

yeah thats what we thought about control but only bit that seems to move is front bit which appears to be for temperature

i think we'll just buy this Architeckt Como Exposed Manual Mixer Shower Valve - Architeckt available at Plumbworld to go with the whoer kit above already purchased, rather than chance the other one which doesnt seem to have on off control with it.
do you think that would work ok?
thanks for all your help

 

[WHPES]

I think the front is for the control. If I remember right the temperature for these mixers is fixed and can't be adjusted by the user (like in a gym changing room), but I suggest you look at the instructions.

I suggest you connect it up with hosepipes from the hot and cold supply to test it and find out how it works before it is actually installed.

many thanks for ll your help, think ill abort the rada might put it on ebay for a tenner to see if someone wants it
do you think the other option i listed will work ok?
thanks

 

[WHPES]

Absolutely No. It is not a thermostatic mixer and therefore unsuitable.

 

[kowalski181]

i just presumed it would be the same as it has 3 inlets?
could you advise what we need to have a mixer shower please?
what should i be typing in ebay or plumbworld to go with the exposed shower kit above ive bought or is it best just to return that?
do you think anyone would buy the rada things thats useless i have as it has no power control only for the temperature?
mny thanks

is this suitable SQUARE 2 WAY THERMOSTATIC SHOWER VALVE MIXER SET on eBay (end time 14-Jan-10 09:40:32 GMT)
