Circulates descaling solution through the heat exchanger for 30 to 45 minutes. It is the core tool for any tankless flush and the reason scale comes out instead of staying in.

What our tankless leak repair and flush covers
Every tankless visit includes a full leak inspection, a descaling flush, and a pressure test. If we find a failed part, we quote the repair before we touch it.
Work order
Tankless Leak Repair & Flushing- Full leak inspection: We check the heat exchanger, all fittings, the T&P relief valve, the drain valve, and the supply lines. An electronic leak detector and moisture meter confirm the source. You get a plain-language explanation of what failed and why.
- Descaling flush: A hose and bucket flush kit circulates descaling solution through the coil for 30 to 45 minutes. That removes the mineral scale that causes most Fort Pierce tankless problems. We show you the water color change so you can see the result.
- Pressure test: After the repair we pressurize the system and watch a pressure gauge for 15 minutes. A thermal expansion tank check is part of this step. If pressure climbs past 80 psi, we diagnose the closed system and recommend a fix.
- Failed part replacement: Gaskets, flex lines, T&P valves, drain valves, and heating element gaskets are common replacements. We carry them on the truck and install with Teflon tape and pipe dope. Parts are quoted before we start, so there is no surprise.
- Photo documentation: You get photos of the leak, the failed part, and the flush before and after. We email them the same day.

Tankless Leak Repair & Flushing in Fort Pierce
A tankless unit that leaks or scales up costs you hot water, gas, and eventually a flooded closet. Fixing it properly the first time is cheaper than replacing it or repairing water damage.
Tankless Leak Repair & Flushing in Fort Pierce means finding where water escapes a wall-hung unit and removing the mineral scale that causes most of those leaks. We open the cabinet, pressure-test the supply lines, inspect the heat exchanger, and flush the coil with a hose and bucket flush kit. If a fitting is cracked or a gasket has failed, we replace it with a braided stainless flex connector or a new heating element gasket and test the line before we leave.
Fort Pierce water runs hard, and that mineral load is what kills tankless units early. Scale builds on the heat exchanger, overheats the coil, and eventually finds a weak point at a fitting or the T&P relief valve. Homeowners call us when they see water under the unit or notice the burner short-cycling. A tankless water heater leak repair Fort Pierce FL near me search usually means the leak has been dripping for weeks, so we treat every call as urgent.

What our tankless service visit looks like
Every call starts with a real conversation about what you are seeing, then a hands-on inspection.
Tools and methods we use
Each method answers a different question. Together they leave very little to guess.
Traces hidden leaks behind walls and inside cabinets without tearing anything out. We use it to confirm the source before we start replacing parts.
Shows temperature differences that reveal a leaking fitting or a scaled heat exchanger. It confirms what the pressure test suggests and speeds up diagnosis.
Monitors system pressure during the test phase. If pressure climbs past 80 psi, we know the closed system needs a thermal expansion tank.
Measures water content in drywall, framing, and flooring around the unit. It tells us how far a leak has spread and whether drying is needed.
When Fort Pierce homeowners call us
A homeowner in Fort Pierce North sees water under the tankless unit on a Saturday morning and cannot get hot water.
We take the call, walk them through shutting the isolation valves, and dispatch a technician the same day.
HomesA Hutchinson Island condo owner notices the hot water temperature dropping and the unit short-cycling every few minutes.
That pattern points to scale on the heat exchanger.
HomesA landlord with rentals in Fort Pierce South needs two tankless units serviced before new tenants move in.
We schedule both units in one trip, flush each one, and inspect the fittings, drain valves, and relief valves.
BusinessesA White City homeowner on well water calls because the tankless unit is leaking and the water smells metallic.
Well water carries more mineral content than city water, so we check the heat exchanger closely.

How tankless service runs in Fort Pierce
Fort Pierce sits on some of the hardest water in St. Lucie County, and that shapes every tankless job we run. City water carries high mineral content, and well water in White City and Indian River Estates is worse.
Hutchinson Island
Salt air corrodes flex lines and fittings faster here. We check connections closely on every beachside call and often replace the original line with braided stainless.
Fort Pierce North
Older homes with tight utility closets make access harder. We plan extra time for the flush and bring a camera to inspect connections we cannot reach by hand.
White City
Well water carries heavy mineral content. Units here scale up faster, so we often recommend flushing every 8 to 10 months instead of annually.

PhotoLeaking Navien unit in Lakewood Park
Before: A 5-year-old Navien unit dripped from the bottom of the cabinet for weeks. The homeowner saw water stains on the floor and the burner was short-cycling. The heat exchanger was heavily scaled and the heating element gasket had failed.
After: We replaced the gasket, flushed the coil with descaling solution, and pressure-tested at 75 psi. The drip stopped, the short cycling ended, and the hot water temperature came back up. The whole job took under three hours.
Weeping T&P valve on Hutchinson Island
Before: A condo owner noticed water in the drain pan and a constant drip from the discharge pipe. The T&P relief valve was weeping and the system had no thermal expansion tank. Pressure was climbing past 90 psi during heating cycles.
After: We replaced the T&P valve, installed a thermal expansion tank, and tested the system at 70 psi. The drip stopped completely and pressure stayed steady through two full heating cycles. No more water in the pan.
Corroded flex line in Fort Pierce South rental
Before: A landlord found water running down the wall behind a tankless unit in a rental. The original flex line and nipple were corroded through. The tenant had been without reliable hot water for days.
After: We replaced the line with a braided stainless flex connector and dielectric unions, then flushed the coil and pressure-tested. The leak stopped, the tenant had hot water that evening, and the wall stayed dry.
Tankless problems we fix in Fort Pierce
Most tankless calls come down to one of a handful of failures.
Tankless water heater leaking from the bottom
Water pools in the cabinet and drips into the wall or floor below. Over weeks, that rots framing, stains ceilings, and grows mold.
Scale buildup choking the heat exchanger
Hard Fort Pierce water deposits minerals on the coil. Flow drops, hot water temperature falls 10 to 20 degrees, and the burner runs longer.
Leaking T&P relief valve
A weeping relief valve drips constantly from the discharge pipe. It often means thermal expansion is pushing pressure past the valve.
Corroded flex line or nipple
The connection between the wall and the unit corrodes over time, especially in humid coastal air.
Why Fort Pierce homeowners flush tankless units
A tankless unit that gets flushed every year lasts years longer than one that never does.
Stop the drip fast
A leaking tankless unit can dump 2 to 5 gallons a day into a closet or wall cavity.
Restore full hot water
Scale on the heat exchanger cuts flow and drops your hot water temperature 10 to 20 degrees.
Cut your gas bill
A scaled heat exchanger makes the burner run longer to hit the same temperature.
Avoid a flooded closet
Tankless units sit above drywall, flooring, and sometimes a finished ceiling. A slow leak rots the framing and grows mold before you see it.

What Fort Pierce customers say
Our Navien started dripping from the bottom of the cabinet and we could not figure out why. The tech found a failed heating element gasket and a scaled-up heat exchanger. He flushed the unit, replaced the gasket, and pressure-tested everything. No drip for six months now, and the hot water is noticeably hotter. Worth every dollar.
I manage four rentals and two of them have tankless units. Water Heater Leak Pros flushed both and replaced a T&P valve that was weeping. They showed me photos of the scale that came out, which was disgusting. Scheduling was easy and they worked around my tenants. I use them for all my units now.
Condo unit leaked into the hallway ceiling and I needed it handled fast. They came out same day, shut the water, found a cracked flex line, and had it replaced before dinner. The tech also checked the pressure and told me my expansion tank was shot. Fixed that too. No more water where it should not be.

Describe what you are seeing and we will point you to the right next step.
(772) 264-9364Once a year is the right schedule for most Fort Pierce homes, because our water is hard. If you are on a well in White City or Indian River Estates, every 8 to 10 months is safer. We check the scale level during the flush and tell you if your unit needs a tighter interval.
The most common causes are a failed heating element gasket, a cracked braided stainless flex connector, a leaking T&P relief valve, or scale that has corroded a fitting. On units over 8 years old, a cracked heat exchanger is possible. We pressure-test the supply lines and inspect the coil to find the exact source. Most leaks are a same-day repair with parts we carry on the truck.
Units mounted high in a closet or behind finished walls take longer. We quote the full job before we start, so you know the number up front.
Yes. Florida water, and Fort Pierce water in particular, carries high mineral content that deposits scale on the heat exchanger. That scale insulates the coil, raises your gas use, and eventually cracks fittings or the exchanger itself.
