Mira Excel no water

Hi



I have a pre 1996 Mira Excel. We had it in the house we moved to and we have been there four years now. I have to be honest and say it has had some niggles with flow rates sometimes being slower than others and also the on of knob being stiff. However, it has now died. On off know turns, but no water. I have taken the front cover off and the teeth all look fine, but evening turning the cartrige manually gives no water. I can see that the mechanism moves in and out OK I am sure I was told we had a downstairs pump as we have an unvented system, but is there a way to identify if the pump or the Excel has a fault, as I don't want to buy one to find it's not at fault. Could there be a blockage

Hi

 

If you have problems with an Excel then it's best just to replace the cartridge, however it is probably worth stripping the cartridge out and checking that the inlet filters are clean, before buying a new cartridge.

 

 

Turn off hot and cold water supply

 

Pull front temperature knob off The rest of the knob assy. just unclips

 

Remove 4 screws that hold cartridge into body

 

Pull old cartridge forward shouldn't be too tight

 

Set new cartridge for High/Low pressure (instructions with cartridge)

 

Slip new cartridge into place remember to check that the new seals are all in place (and don't drop out as you push back)

 

Tighten screws be careful not to over tighten

 

Refit knobs.

 

Turn on water and test. (Occasionally you will have to reset the cartridge temperature, instructions with cartridge)

 

Easy peasy!!!!

 

 

Cartridge   Mira 903.33  This cartridge supersedes the previous high and low pressure versions
