Let the tank have a input and output pipe. If pressure instantaneously increases the tank cannot fill instantaneously so current will flow through output pipe. If pressure increases slowly the tank has time to fill as well. This explains low impedance of capacitor for low frequency (slow change) and high impedance for high frequency (fast change).
How to properly discharge a high voltage capacitor?
I have recently blown a capacitor on my home made emp. I have got the perfect replacement which is an electrolytic capacitor, 330v, 140 micro farads.

capacitor
The peak voltage is actually higher, and the peak voltage is what charges the capacitor. If the secondary windings operate at 12V RMS, then the capacitor will charge to a peak of about 17V. Thus, at the peak, there is 5V of dropout. On each cycle, the capacitor charges to the peak voltage. Then, it discharges as the regulator draws current from it.
How do I increase the voltage limit by connecting same capacitors?
Connecting two identical capacitors in series, each with voltage threshold v and capacitance c, will result into a combined capacitance of 1/2 c and voltage threshold of 2 v.. However, it is far better to get a single capacitor that meets the higher voltage threshold on its own as combining capacitors in series will also lead to a higher Effective Series Resistance (ESR).
filter
I expect C1, C2 and C3 in your diagram are filtering capacitors. They filter unwanted high frequencies from power line. Their impedance is low for high frequency signal and high for low frequency signal. This results in acting like a short circuit for high frequency signals.
