My pump seems to cycle far too often and I assume I need a new one. Since they come in a lot of different sizes, I was wondering if I should get a larger one. There's only the two of us but I do like LOOOONG showers.

How often is "too often"?
What type of tank, galvanized pressure tank or painted bladder tank"
How big is your present tank.
Does the pump cycling occur when water is running.
Pump cycling is caused other factors not by pump itself.
