General Plumbing & Pricing

How much does a plumber cost in Jacksonville?

While costs vary by project, standard residential plumbing services in Jacksonville typically range from $150 to $500 for common repairs like drain cleaning or faucet installs. Complex jobs like slab leak repairs or water heater replacements fall into higher price brackets. We always provide a realistic, upfront price range before we begin any work so you are never surprised by the bill.

What should I do if I have a plumbing emergency?

If you have an active leak or flood, immediately locate your main water shut-off valve and turn it clockwise to stop the flow. Once the water is off, call RiverCity Plumbing at for 24/7 emergency dispatch. Fast action can save you thousands in water damage and mold remediation costs. See our full emergency guide →

Water Quality & Treatment

How hard is the water in Jacksonville, FL?

Jacksonville’s water is classified as “extremely hard,” averaging 15.3 grains per gallon (GPG) of mineral content. This is more than twice the national average and causes rapid scale buildup in your pipes, water heaters, and household appliances. This high mineral count is a result of our water being sourced from the limestone-rich Floridan Aquifer. Learn about our water treatment solutions →

Why does my water smell like rotten eggs in Jacksonville?

That distinct “rotten egg” odor is caused by hydrogen sulfide gas, which is naturally occurring in the Floridan Aquifer, especially in properties using private wells. While generally safe to consume, it’s highly unpleasant. We offer chemical-free aeration and carbon filtration systems specifically designed to neutralize these North Florida odors. Learn more →

Do I need a water softener in Jacksonville?

Yes, a water softener is highly recommended for Jacksonville homes to neutralize the 15.3 GPG hardness. Without one, your water heater’s lifespan can be cut by 50% — dropping from a typical 12 years to just 6 or 7 years. A softener also prevents the white, crusty scale buildup on your expensive kitchen and bathroom fixtures. See our water softener options →

Pipes, Leaks & Sewer

How do I find a slab leak in my foundation?

Common signs of a slab leak include a sudden spike in your JEA water bill, the sound of running water when all taps are off, or “hot spots” on your floor. We use non-invasive sonic and thermal technology to pinpoint these leaks without destroying your flooring. Early detection is critical in Jacksonville, as our sandy soil can wash away quickly under a foundation when a pipe fails. Learn about our slab leak detection →

What is polybutylene pipe and is it in my Jacksonville home?

Polybutylene is a grey plastic pipe used in many Jacksonville homes built between 1978 and 1995. These pipes are prone to sudden, catastrophic failure due to the chlorine in our municipal water, and many Florida insurance companies now require their replacement. If you have grey pipes in your garage or under your sinks, you likely have polybutylene and should schedule a professional inspection. Learn about replacement options →

How often should I pump my septic tank in Florida?

According to Florida Department of Environmental Health (DEH) recommendations, most residential septic tanks should be pumped every 3 to 5 years. Heavy usage or the use of a garbage disposal may require more frequent maintenance to prevent drain field failure. Regular pumping is the cheapest insurance against a multi-thousand dollar septic system replacement.

Water Heaters

Why is my water heater making a popping or knocking sound?

This is a classic Jacksonville problem caused by our 15.3 GPG hard water. As sediment builds up at the bottom of the tank, steam bubbles get trapped under the layer of mineral “rock,” popping as they escape. This is a sign your heater needs a professional flush immediately — and may need replacement soon.

How long do water heaters last in Jacksonville?

While water heaters can last 12–15 years elsewhere, Jacksonville’s “extremely hard” water (15.3 GPG) typically reduces a standard tank heater’s lifespan to just 7–8 years due to sediment buildup. A water softener can extend this back to the national average. A tankless water heater with proper maintenance can last 20+ years even in our hard water.

Emergency Plumbing

How quickly can you get to my Jacksonville home for an emergency?

For residents in the Jacksonville metro area, we aim for a response time of 45–60 minutes for emergency calls. Our trucks are stationed near major landmarks like the Main Street Bridge and Trout River for rapid deployment across all of the 904. Learn about our emergency service →

Do you charge more for after-hours or weekend emergency calls?

We provide upfront pricing for all services, including emergencies. While emergency dispatch fees may apply for after-hours or holiday calls, you will always receive a total price for the repair before we start the work. No surprises — ever. That’s our promise to every 904 customer.
