Frequently Asked Questions

Do you work on remodeling projects?

Yes. We can assist with plumbing installations that are part of kitchen, bathroom, and other residential remodeling projects.

Can new plumbing fixtures improve efficiency?

In many cases, newer fixtures can improve water efficiency and reliability while reducing ongoing maintenance and repair needs.

Do you install customer-provided fixtures?

Installation options can vary by project. We can discuss your plans and determine the best approach for your installation.

Why does my toilet keep clogging?

Recurring toilet clogs can mean there is a larger backup in the pipe. A professional plumber can use tools like sewer cameras, drain snakes, and hydrojetters to clear the clog.

Why is my water pressure suddenly low?

Low water pressure can point to blockages in your fixtures, a valve that hasn’t fully opened somewhere, or even a hidden water leak.

Why does my shower take forever to get hot?

It could be because of the physical distance between your shower and the water heater, the diameter of your pipes, or because of an issue with your water heater itself, like sediment buildup.

Why is there a sewer smell in my house?

A smell of sewage in your house is a warning sign of a backup in your pipes. It is best to call a plumber right away to perform a sewer inspection.

Do I need a permit to replace my water heater?

Permits are typically required for the installation of any water heater. John Owens Services takes care of the permit process for you before beginning the job.

Why are my pipes making banging noises?

Pipes could be loose, water pressure could be too high, or thermal expansion could be causing the pipes to move.
