The water problem finally got resolved today afternoon, after 3 days of no hot water supply.
Turns out dozens of houses were affected from this problem and in fact, happened to visit couple of them only to hear troubles they faced.
Finally relieved to have assurance of a satisfactory bath tomorrow, thanks to Watercare Services. I can see Easter turning better from now onwards. ๐ฑ๐ง๐๐ฟ
