Soil

Much of Dallas sits on expansive clay that swells when wet and shrinks during drought, moving slabs and the pipes in them.

Abrasion and age

Copper lines can wear where they contact concrete, rebar or gravel, and thermal expansion of hot lines adds movement.

What owners can influence

Consistent foundation moisture during droughts, good drainage away from the house, and prompt attention to leak signs.
