Hi Mauro, thank you very much for your response. But being a new water heater and with little use, (only I use it), do you think that so soon, in less than a year the diaphragm could have been damaged? Because I have no idea.
As I was told in this area the water is a bit heavy and very calcified, that's why it seemed logical to me, or what I was told in ORBIS, (that the problem was that it was covered with zarro).
If you think you would try to give the serpentine a wash first. If I use white alcohol vinegar alone, do you think it could be very corrosive?
I understand friend .. you have to discard everything !! ..
According to my experience, so that the coil is clogged with zarro, many more years must pass before this process is consolidated.
A fissure in the diaphragms sounds more plausible.
But it does not hurt that you clean the corrosion factor is low if you use vinegar and industrial alcohol .has the cleaning. !!
If you continue in trouble let me know
Regards!
