Does PEX ever burst from freezing?

It is more forgiving than rigid pipe, but it can still split in severe or repeated freezing, and the brass or plastic fittings can crack. Keeping lines warm is still important.

Water from my neighbor's townhome is coming through our shared wall. Who do I contact?

Start with the neighbor so they can close their valve, then the HOA or management company if the wall or plumbing may be shared. Notify your own insurer and photograph the damage on your side before anything is opened up.

Central Park is within the City and County of Denver, so plumbing permits go through Denver Community Planning and Development. Your HOA may also have its own approval process for exterior changes.

Central Park Pipe Leaks: Newer Homes, PEX and HOA Rules

Newer does not mean freeze-proof

Homes in Central Park were built under modern codes, with plumbing usually kept in interior walls and insulated spaces. Many use PEX, which tolerates freezing better than copper because it can expand somewhat. That reduces risk, but it does not eliminate it. The fittings that connect PEX lines are rigid and can crack, and any line in an exterior wall or above an unheated space can still freeze in a severe cold snap.

The neighborhood's design adds some particular features. Many homes have alley-loaded garages, some with living spaces or accessory units above them. Rowhomes and townhomes share walls. Some homes have bump-outs and cantilevered rooms with plumbing in the floor, exposed to the cold underneath.

Another common source of leaks in newer homes is fixtures and appliances rather than pipes: supply lines under sinks, refrigerator lines, washer hoses and tankless water heater connections. These fail in any season.

Central Park homeowner checklist

Find the main shutoff, often in a mechanical closet, basement or garage
Check whether your townhome has its own main or shares one
Inspect supply lines under sinks and toilets and replace aging ones
Keep the garage door closed in winter if living space or plumbing sits above or beside it
Read your HOA documents for who maintains what in attached homes
Consider leak sensors near the water heater, washer and refrigerator
Keep construction documents and plumbing plans if you have them
