Plumbing Services in Plano, TX

Plumbing in Plano at a glancePlano grew quickly from the 1970s through the 1990s, and most of its homes sit on post-tension or conventional slabs over the expansive Blackland Prairie clay that runs through Collin County. As the soil shrinks in drought and swells after rain, foundations move, stressing supply lines and drains underneath. Homes from the 1970s and early 1980s commonly have cast iron drains under the slab that are now 40 to 50 years old.

Plano buys treated water from the North Texas Municipal Water District, which typically runs a temporary chlorine maintenance period each year when customers may notice a stronger chlorine taste or smell. The February 2021 winter storm showed how exposed pipes in attics, exterior walls and garages are in North Texas homes built mostly for heat.

What makes Plano plumbing different

Cast iron under aging slabs

Drains under 1970s–80s slabs scale, crack and develop bellies as soil moves.

Expansive clay

Soil movement stresses supply lines and drains and contributes to slab leaks.

NTMWD chlorine maintenance

A temporary seasonal change in disinfection can change taste and odor; it isn’t a plumbing failure.

Attic plumbing and heaters

Many homes have water heaters and supply lines in attics that need freeze protection and pans.
