My uninformed guess would be corrosion. Salt water will (eventually) destroy everything you know and love

As an ex-firefighter not based out of antarctica, you are absolutely right. Sea water is extremely damaging to pumps. We use it as a last resort, and often have to refurb pumps when we do.

Eventually?

Yes. Not immediately, but eventually like parent said.

Is there something lost in (your) translation, or are your single word post just extraordinarily hard to comprehend?

If you had a question, please use more words. Seems like you are just being stubborn or otherwise not wanting to add to the discussion.

I was trying to make a joke about how bad salt water corrosion is.
