Frequently asked questions

West Covina homes were built in the 1950s through the early 1970s — what does that mean for their drains?

Homes of that era typically have clay or cast-iron laterals — plastic pipe only took over in the 1970s. Clay and cast iron develop root intrusion and bellies with age, so recurring clogs justify a camera inspection rather than repeat cabling.

Are tree roots a real problem for West Covina sewer lines?

Yes — the mature canopy over West Covina's older neighborhoods sends roots into every joint of aging clay laterals. If a main-line clog comes back within months, a camera inspection will almost always show root intrusion; jetting plus scheduled maintenance usually controls it, severe cases need lining or replacement.

Who is responsible for the sewer lateral — me or the city?

In most California cities the homeowner owns the lateral all the way to the main (sometimes to the property line). Rules vary by city, and some require a lateral inspection certificate when you sell — check your local ordinance.
