Shower leaking - Mira event xs thermostatic shower

This is a simple task if one have some basic knowledge with setting seals and the like. It should be kept in mind that the use of special tools that may be required. However I'm not advising you carry this out repair. Erring on the side of caution, I suggest having a certified professional deal with it. You may do a seemingly good job but later having a catastrophic failure if something is overlooked.

I would suggest using a professional to ensure the job is completed correctly using the right tools and parts. Usually with things like continuous drips and leaks the problem is down to a wrongly seated washer/seal or may have slowly degraded over time.

Hi Kimptoc - In line with other tradesmen that have responded to your question, I would be reluctant to carry out this job yourself unless you feel completely competent in isolation the electrical supply to this unit, which is likely to be supplied with electricity of a very high Amperage. That being said, from my personal experience, I think the problem you have here is related to component 'H' in the diagram from the link you posted. This component acts as a pressure-relief valve and usually contains a small rubber ball. The rubber ball is designed to pop out of its housing if the flow of water through the unit becomes restricted. More often than not, this is caused through limescale build up in the shower head. Once this happens you have a constant leak. It's a relatively simple job if you are electrically competent enough to remove the cover from the unit to access it. Don't forget to de-scale the shower head or renew it before using the shower again after the repair has been made. Hope this helps. Rick
