Electricity question: Why does a bathroom bulb flicker when we switch on the hot water geyser?

Answer 1

I suspect you are using an electric hot water heater?

Let a qualified person check the wiring. Meanwhile stay away from that death trap!

Answer 2

Not knowing what a "hot water geyser" is, I can only suggest you get an electrician to look at it.

Some flicker may be normal if you are switching in a large electrical load when you turn that thing on. Or it may indicated faulty or marginal wiring.
