Talk to me about the pressure flush toilet. Is that where the water
pressure pressurizes an accumulator?

They're pretty simple, the pressure tank is inside the toilet tank rather
than having a float with flapper valve. They're sold in every hardware
store and nothing fancy is required other than just a different type of
toilet. The water pressure builds up inside the pressure tank and it is
water efficient and produces a much more powerful flush. So instead of
having to flush 5 times with a traditional toilet because the contents in
the bowl overwhelm the weak gravity flush, you flush just once with a
pressure toilet. So it saves water too.

So this is a special toilet, not something that can be retrofitted.
