A $46.5M Pied-à-Terre's Persistent Water Problem

A lawsuit filed in Manhattan Supreme Court last month reveals an unusual headache for the owner of a $46.5 million condo at 220 Central Park South, the iconic Billionaires' Row tower. For seven years, the 4,300-square-foot pied-à-terre on the 14th floor of the building's 'villa' section has produced milky, white hot water from its kitchen and bathroom taps, accompanied by a chalky residue that coats fixtures, according to the complaint.

The property, purchased in 2019 by an LLC linked to Arie Jusidman, son of Mexican hardware magnate Daniel Jusidman, has seen no improvement despite the installation of new filters and multiple building-led interventions. The board and its manager have pointed to an unlikely culprit: the building's extremely low occupancy. An August 2024 email from the building manager to Jusidman stated the top zone of the villa had 'extremely low occupancy, the lowest we have seen in both the Villa and the Tower,' and suggested that a lack of use had led to a build-up of deposits in the water system.

Water tests commissioned by the board in 2024 found elevated levels of zinc, aluminum, iron, and copper, which the board's consultant attributed to 'a lack of use' and recommended continued flushing. A second consultant, hired directly by the Jusidmans earlier this year, also found high levels of metals and concluded the issue was likely 'plumbing-related metal leaching.' After years of what the owner called 'excuses and promises,' the suit seeks damages and a court order to force repairs. A spokesman for the condominium's homeowners' association called the lawsuit 'without merit,' adding that the building's own water tests have always shown the water to be safe, and that the unit's plumbing was installed by the owner—not the developer.

Why Stagnant Pipes Turn Tap Water Cloudy

The Physics of Idle Water Pipes

The core of the dispute rests on a well-understood phenomenon: water that sits unused in pipes for extended periods can degrade. Ibrahim Ahmed, founder of Pegasus Consulting Group, told Curbed that 'heat and stagnation can both accelerate corrosion and metal release.' In a building where many units remain empty for weeks or months, water in the lines loses its residual chlorine disinfectant, giving metals and minerals more time to leach from plumbing components. Dennis Kanakis of Olympian Water Testing explained that sediment can settle, and biofilm—bacteria—can establish, all of which are more likely in underused systems. Regular use and periodic flushing typically keep these problems at bay, but a 'tier of a building used largely as pied-à-terre fits that pattern well.'

Why 220 Central Park South's Occupancy Matters

The villa section of 220 Central Park South, home to fewer than 20 apartments, sits just below Sting's $66 million penthouse, and like many Billionaires' Row residences, many of its units serve as asset-parking investments rather than primary homes. The resulting low occupancy creates the very stagnation that the experts describe. The irony is stark: a building celebrated as a pinnacle of luxury living has seen its most valuable apartments sit empty, and that emptiness appears to be undermining the experience of one of the few owners who actually uses his unit. The building's defense—that the owner installed his own plumbing and that no other residents have complained—will test the limits of condo board responsibility for water quality in a tower where intermittent use is the norm rather than the exception.
