What are the signs of a clogged drain?

Common signs include slow draining sinks, tubs, or showers, water pooling around drains, gurgling noises from pipes, bad odors coming from drains, frequent backups or overflowing fixtures, and multiple clogged drains at once.

What causes drain clogs?

Common causes include grease, oils, and food scraps washed down kitchen sinks, hair, soap residue, and toiletries in bathroom drains, flushing items not meant for toilets, mineral buildup from hard water, tree root intrusion in outdoor drain lines, and old deteriorating pipes restricting flow.

Yes, Precision Flow Plumbing offers same-day and 24/7 emergency drain services throughout San Francisco. We understand that clogged drains can disrupt your entire home and require immediate attention.

How can I prevent future drain clogs?

Prevent clogs by avoiding pouring grease and oils down drains, using drain strainers to catch hair and debris, not flushing items other than toilet paper, running hot water after each use, and scheduling regular professional drain maintenance.

Why are multiple drains clogged at once?

When multiple drains clog simultaneously, it usually indicates a blockage in the main sewer line rather than individual drain issues. This requires professional diagnosis and may involve tree root intrusion or a major obstruction in your main line.
