Creda cylinder replacing

I am competent in electrical work and would like to know if it is a good idea to replace the cylinder/boiler in my shower. having looked I do wonder if this would be quite simple as my concerns are the water connections to the cylinder and how they are sealed. Any advice would be welcome.

First check out the video above to be sure that the can is not working.


I am often asked “Is this a DIY job” to be honest I can’t answer that, because without knowing someone, it isn’t possible to assess their skills?

I should say that most jobs on showers although relatively easy (from my point of view) can be fiddly and an extra pair of hands, long thin fingers and the strength in your hands of an all in wrestler are a help!

The secret is, observing very carefully when things are taken to bits, their order and orientation, taking notes and/or photos as you go can also be a help.

When you are working with electricity and water so make sure it is switched off and turned off before you start.

If you think you can do the job but aren’t just that confident, it may help to buy the part and compare it to the faulty part, you will then be able to see where the screws, wires, nuts, or washers etc. go, if then you think it is to complicated, at least you will have the part when the plumber or electrician arrives.

We will always be here to offer help and advice if you run into a problem, however it is not the same as being on site where we can get the overhaul picture, if you are still not sure, now is the time to call in a professional.


"O" rings are used to seal most connections.
