Ok guys, I'm the one who wrote to ST about this issue
I have called up Alfie today to clarify things and he has expressed interest in garnering help from us hobbyists on how to better maintain the system.
I just want to say that on my side, Alfie had given me a very comprehensive explaination about the whole issue and I urge all who posted in this thread to give Alfie a call to clarify things.
Like Conrad had mentioned, this issue should have already given us a wake up call that every post we made can have an impact and can be used as evidence against us.
All in all, I wish to express my deepest apologies to Suntec if my letter to ST had affected them in any way. But if you think about it, had I not written to them, someone else will and I'm sure Suntec will make a public clarification and put this matter to rest.
In conclusion, I hope that the tank will go on well and should the maintenance team need any help from me, they can always PM me.
Cheers
