Recently come across what is becoming a seriously problematic Fortic Tank( I`m sure they do go by different names but at this moment just cannot remember)
The cylinder is situated in a loft space, it is fed directly.
Sometime last year their hot water stopped working so I changed the thermostat in the immersion heater and job done.
About a year later the guy calls me back as he has water coming through the ceiling. I check the cylinder and notice the water in the header tank is warm, so I automatically assume the thermostat has gone again and it has boiled over. ( For some reason the installer has sited the overflow higher than the cold feed..... muppet).
So I change the thermostat. When I turn the water back on I notice the ball valve is letting bye, so I go ahead and change that.
I pressume over the years this has happened before as there was staining to the ceiling, and two trays under the cylinder, probably put there to catch water.
Anyway fast forward four months and the thing boils over again, this time taking part of the ceiling with it.
So the customer, probably at this point thinking i`m pretty incompetent, rings his house insurance guys(usually he rings me if he has any probs) and their task was to stop the leaking.
For some reason the guy changed the ball valve(????????), the one I had changed a few months earlier, why the customer did`nt tell him this I don`t know!
The guy also advised that there could be a split in the cylinder and to keep an eye on it.
Now I am sure that this problem is gonna happen again, obviously the positioning of the overflow needs sorting.
But I now see myself with only two options........ change the immersion heater or completely change the cylinder alltogether as its just becoming problematic.
I have just googled internal diagrams of combination cylinders and can now see that the guy could only be right about the cylinder splitting if it was an indirect cylinder.
TBH I don`t deal with this type of cylinder too often so perhaps some of you knowledgeable heads could fill me in with some help and advice.
P.S the electrics at his place are quite old and sometimes his lights pop out every now and again. probably irrelevant.
