Hi all,
Finally getting around to changing some of the older taps in the home.
We have a few inconsistencies, where both hot + cold taps turn off the "normal" way - counter-clockwise (CCW), but in other rooms, the left (hot) tap turns on CW while the right (cold) tap turns on CCW - and even the opposite way in the shower!

Before I go out and buy some new taps, are these simple to change (the direction) up? Would there be any considerations I need to make?
Also, I might lump this question here also, but I noticed in many sinks the water pressure isn't great, but then one day one of these poor water pressure taps suddenly popped out the "aerator" (?) and the pressure was decent after fortunately,
Are these available to buy at Bunnings? Do they come in standard sizes? And do they offer variants which can improve water pressure?

And finally, also related to water pressure, the toilet tanks seem to refill at a slow pace, is there a fix to this (anything similar to the faucets?) or is it just based on the cistern (I plan on replacing the existing cisterns).
Thanks everyone, appreciate the patience on this wall of text 🙂
