Frequently Asked Questions

What plumbing service work can John Owens Services help with?

Our team helps homeowners with practical plumbing service needs in Sebastopol, including troubleshooting, repairs, replacements, and recommendations for long-term reliability.

How do I know whether to repair or replace something?

We start by looking at the condition, age, repair history, and safety of the system. Our preference is to maintain first, repair when needed, and replace only when that is the better long-term choice.

Do you help with remodeling projects?

We do! Kitchen, bathroom, and other home remodels are projects we can provide plumbing installations for.

Why are my pipes making banging noises?

Loose fittings, high water pressure, or pipes expanding from the water pressure can be the cause of banging sounds.

Should I repipe my home?

If you’re noticing discolored water, recurring leaks, low water pressure, or your plumbing system is around 40-50 years old, it might be a good idea to repipe.

Do you install customer-provided fixtures?

This depends on the specifics of the installation project. We can discuss all options with you before any work begins.

Why does my toilet keep clogging?

This could be a sign of a larger clog deep in the system that needs to be cleared. Our plumbers can use a tool like a hydrojetter to clear tough clogs.

Why does my shower take forever to get hot?

It could be your shower’s physical distance from the water heater, the diameter of your pipes, or because there is a problem with the water heater itself.

Do I need a permit to replace a sewer lateral?

You will typically need a permit for a job like this. John Owens Services can handle the permit process for you for any plumbing repair or installation.
