Basically break tank is the water tank at the mid floor of condo to pump water up to top floor. In my line of work as a professional property consultant, I've seen condos withOUT breaktank, and trust me, they are a huge huge engineering nightmare to maintain due to constant pipe overpressure.

As long as machines are properly maintained and not too noisy, it shouldn't be a bad thing. I would even find it a plus as water pressure would be better.
