John Owens Services provides plumbing repair in San Anselmo, which sits low in the Ross Valley where San Anselmo Creek has flooded more than once, and that history shows up in the plumbing. The downtown Victorians and early-1900s bungalows often still carry aging galvanized or cast-iron lines, and the hillside homes up in Sleepy Hollow and Seminary bring their own water pressure and drainage quirks. We have worked on San Anselmo plumbing since 1986. We find the real problem, explain the repair clearly, and fix it without the upsell: leaks, running toilets, failed shutoff valves, low water pressure, drain backups, and urgent issues that should not wait until morning.

We always do our best to prioritize repair and maintenance over immediate replacement. But when replacement is the best solution, we are committed to offering top equipment for plumbing installations. This includes shower valves, toilets, garbage disposals, faucets, water heaters, and more.

Why San Anselmo Homeowners Choose John Owens

We do not work from a generic checklist. Pipe age, access, fixture condition, water pressure, drain behavior, and past remodels all shape the right repair. John Owens Services is local, licensed, and used to working in occupied homes where clean communication matters. We tell you what is urgent, what can wait, and what should be watched.

Frequently Asked Questions

Why does my toilet keep clogging?

As with any recurring plumbing clog, this can point to a larger blockage deep in the system. It is a good idea to have a plumber inspect the sewer pipe and provide a solution to clear the clog, like hydrojetting.

Why do I have low water pressure?

This can come from blockages somewhere in the fixtures, a hidden leak in your plumbing, a valve that has not opened all the way, or outdated piping.

Do I need a permit to replace a water heater?

You usually will need a permit for a water heater installation. If you hire John Owens plumbers for the job, they can take care of that process for you.

Why is there a sewer smell in my house?

A smell of sewage might mean there is a backup happening in your pipes. It is vital to call a plumber right away before any damage occurs.

Should I consider repiping my home?

Repiping can be a good solution for plumbing systems that are 40-50 years old and if you have low water pressure, rusty water, or frequent leaks.

Why did my water bill jump so high?

An unexplained increase in water bills are a big red flag that indicate a possible hidden water leak. John Owens offers leak detection services to locate plumbing leaks.

Do you install customer-provided equipment?

We can discuss installation options once we’ve inspected the issue and work with you to provide a solution that satisfies you and works best for your plumbing.

Why are my pipes making banging noises?

This might be because of high water pressure, loose fittings, or the pipes expanding because of the temperature of the water.

Do you work on remodeling projects?

Yes! We can assist with bathroom, kitchen, and other plumbing-based remodeling jobs.
