Yes the tap water is yellowish few months ago, since I noticed my drinking jar is yellowish then.
Dun know why there's so many spiders came into my hse, they are everywhere....OMG! So far i saw those long legs type & the black, bigger, short legged type. Although try cleaning up my hse, they also still intruding into my house now & then. Anyone having this problem or it's beocs we have a lot of insects flying in that's why...
