South Cypress around Katella Avenue includes single-family neighborhoods, some attached housing such as townhomes and condominiums, and commercial and business areas. Building ages vary more here than on a single tract street, so the drain materials do too: older homes may have cast iron and clay, while later construction typically uses plastic drain pipe.

For attached housing, the big question is often not how to clear a clog but whose clog it is. A drain shared by several units may be the association's responsibility rather than any one owner's.

Whose line is it?

  • IfYou own a detached single-family homeThenThe building drain and at least part of the lateral are generally yours; check with the city about the section near the street.
  • IfYou own a townhome or condoThenCheck your association documents; shared drain lines are often common area.
  • IfYou rentThenReport to your landlord or property manager.
  • IfYou lease commercial spaceThenYour lease usually defines responsibility; check with the property owner.

Common questions

Is the race course area on the city sewer?

Check with the City of Cypress for sewer service details for any specific property.

Do newer plastic drains clog less?

They are smoother and resist roots better at glued joints, but grease and wipes still cause clogs.

Can I hire my own plumber for a shared line?

Check your association rules first; there may be an approved process.
