Frequently Asked Questions

What types of leaks can you locate?

We are a leak detection plumber that can locate slab leaks, underground water line leaks, gas leaks, radiant heating leaks, and many other hidden plumbing leaks.

Will you have to open my walls or floors?

The goal of our plumbing and gas leak detection company is to accurately locate the leak before any demolition begins with professional video leak detection technology. Once we’ve confirmed the source, we’ll explain exactly what access is needed to complete the gas or water leak repair.

Can you repair the leak after finding it?

Yes. Once we’ve identified the problem, our licensed plumbers can recommend and complete any slab leak repair, gas leak repair, or plumbing leak repair.

Do you work on older homes in Santa Rosa?

Yes. We regularly work on both older and newer homes throughout Santa Rosa and understand the plumbing systems commonly found in each.

What should I do if I smell natural gas?

Leave the area immediately, avoid creating sparks or flames, and contact your gas utility. After the area has been made safe, we can inspect your gas piping. Consider installing gas leak detectors to prevent this.

Do you have experience with Eichler homes?

Yes. Our team has extensive experience diagnosing plumbing and radiant heating systems in Eichler homes throughout the North Bay. We offer slab leak detection in order to identify possible leaks in the concrete slab.

Why did my water bill suddenly go up in Sonoma County?

If you’ve noticed an unexplained rise in your water bill, it is possible you have a hidden leak. Leaks can come from irrigation systems, toilet flappers, or an underground pipe leak without anyone noticing at first.

Can a plumber find a hidden leak without opening walls or floors?

Yes, there are many methods of finding leaks without going inside walls or floors, such as thermal imaging leak detection, acoustic listening devices, tracer gas leak detection, and the FAST Aqua M300 device.

Do I need a plumber and a leak detection specialist?

If you know or suspect you have a leak somewhere in your home but don’t know where it is, you need a leak detection specialist. If you have found the source of the leak and need a repair, you need a plumber. John Owens technicians are onestop plumbers: plumbing and leak detection all in one!
