Element is scaled up.....noises are from element heating and scale popping
Might want to re-establish the 'air pocket' cause flipping the T&P Relief Valve open has most likely gotten rid of 'air pocket'
Air pocket is used to absorb increase in pressure due to water swelling when heated. Air can be compressed.......water can't
Turn off water supply
Open nearest faucet hot side to relieve pressure
Open T&P via lever until water stops flowing then let it Snap closed
Close faucet
Turn on water supply
