My kwikot geyser trips when I turn it on its 7 year old

There must be something in the watersection causing this or its connected to old pipes bring out rust

Hi, I suppose that you talk about an electric geyser.
It is important to know if tripping is the result of a shortcut or via the earth leakage switch.
In the fist case, often insulation is somewhere gone.
But more likely is the second possibility.
then there can be somewhere a little leak in the water circuit and condensation goes on the wires and they become conductive to small currents, specialy to the earth wire.

It sounds like the tank is leaking. Without the information as to where the leak is the only answer I can suggest is to replace it.

Use hair dryer and see if you can dry out parts.
Often, when electronics get wet, they cannot be repaired... like dropping cell phone in bucket of water.
