Why a late 1970s tri-level may be hiding gray plastic pipe
Willow Park homes are mostly tri-levels from the 1970s and early 1980s. Polybutylene supply pipe was made from 1978 to the mid 1990s and was installed in millions of homes, so a Willow Park house built in or after the late 1970s is worth checking. It is a flexible gray plastic, often joined with plastic or metal crimp fittings, and it tends to fail at those fittings without much warning.
You can sometimes spot it where the main line enters the house, at the water heater or under sinks. A tri-level layout spreads plumbing across three floor heights, so supply lines run through ceilings and walls between levels. A failed fitting on the upper level can leak for a while before water shows on a ceiling below. Older homes in the neighborhood are more likely to have copper, which holds up better.
Drain lines in these homes are often cast iron or early ABS plastic, and the sewer lateral to the city main is the owner's responsibility under Aurora City Code. The expansive clay soil under much of the Front Range moves over decades, which can stress both buried lines and the spots where pipes pass through the foundation. A short inspection tells you what you actually have before you budget for any of it.

Laterals from this era collect roots and buildup. A backup in the lowest level is usually the main line, and clearing it gets every drain moving again.

How to check your own Willow Park home

- Look at the water entryFind where the main water line comes through the foundation. Gray plastic pipe with crimp rings is a strong sign of polybutylene inside the house.
- Watch the meterTurn off every faucet and appliance, then check whether the water meter keeps moving. If it does, a hidden leak is likely somewhere in the system.
- Note ceiling stains earlyA small yellow ring on the ceiling of the middle level often means a slow leak from the floor above. Call before the drywall softens.
Questions
Plumbing questions from Willow Park
How can I tell if my Willow Park tri-level has polybutylene pipe?
Look at exposed pipe near the water heater, under sinks and where the main line enters. Polybutylene is usually gray, flexible plastic about the size of a garden hose, often joined with copper or aluminum crimp rings. If you are not sure, we can identify it during a short visit.
Is it worth repiping a Willow Park home that has not leaked yet?
Many owners choose to repipe before a failure, because polybutylene tends to fail at fittings without much warning and a leak between levels can damage several rooms. It can also make a sale easier. If you prefer to wait, we can inspect visible fittings and replace any that look stressed.
How long does repiping a tri-level in Willow Park take?
Most tri-level repipes take a few days, depending on the number of bathrooms and how the walls are finished. We keep water service on overnight whenever possible and patch access openings neatly so the drywall finisher has a clean start. Aurora requires a permit for repiping, and we pull it.
