Pipe Material Comparison

Filter by use, tap up to three materials and compare lifespan, cost, hard-water tolerance and more, with notes on how each performs in Central Texas.

PEX-A	40–50+ years	The most common repipe choice in Central Texas slab homes, usually routed through the attic.
PEX-B	40–50 years	Standard in many production homes built along the corridor since the 2000s.
Copper Type L	50–70 years	A premium repipe choice; exposed copper was widely damaged in the 2021 freeze.
Copper Type M	30–50 years	Common in 1970s–90s Texas homes; repeated pinholes often lead to a repipe.
CPVC	40–50 years	Found in many 1990s–2000s homes; older CPVC in hot attics can turn brittle.
PVC (DWV)	50–70 years	Standard drain material in most homes built since the 1980s.
ABS (DWV)	50+ years	Less common locally than PVC; check transitions carefully during repairs.
Cast iron (no-hub)	50–100 years	Original under-slab cast iron in mid-century Austin and San Antonio homes is a common failure point.
Galvanized steel	40–60 years (most are past it)	Found in pre-1960s homes in historic areas of Georgetown, Austin, San Marcos and New Braunfels.
Polybutylene (PB)	Unpredictable	Common in corridor homes built roughly 1978–1995; most owners should plan a repipe.
HDPE	50–100 years	Popular for buried water services and site utilities where clay soils move.
Stainless steel	50+ years	Common in food, beverage and lab facilities along the corridor.

// FAQ

Good to know

Which pipe is best for a Central Texas repipe?

For most slab homes, PEX-A run through the attic is the best mix of cost, freeze tolerance and speed. Type L copper is the premium choice where you want rigid, UV-proof pipe. The right answer depends on your water chemistry, attic space and budget.

Should I replace polybutylene or galvanized pipe?

Yes, plan for it. Polybutylene was used widely in 1978–1995 and is prone to sudden failure; galvanized steel corrodes from the inside. Replacement on your schedule beats replacement after a flood.
