Boiler repair

Hot water boilers heat with water moving through pipes, baseboards and radiant floors, which makes them as much a plumbing system as a heating system. We repair the boiler plumbing and keep the water moving.

Boiler problems we handle

  • Leaks at the boiler, fittings or radiators
  • Pumps and circulators that are noisy or not moving water
  • Pressure relief valves that drip or discharge
  • Waterlogged or failed expansion tanks
  • Air in the system and banging pipes
  • Zone valves and mixing valves
  • Backflow protection on the boiler fill line

Call us if your boiler

  • Leaves cold spots or cold rooms
  • Bangs, gurgles or whistles
  • Shows pressure that climbs or falls
  • Has water around the base
  • Keeps tripping or shutting off
  • Is losing water you keep refilling

Radiant floors and combination systems

Some homes around the lake use radiant floor heat or a combination system that makes both heat and hot water. These systems depend on good circulation and the right water temperature at each zone. We troubleshoot pumps, mixing valves and piping to get even heat back.

Where we provide boiler repair

We work out of our office on Harmony Road in Eatonton and cover all of Putnam County, the communities around Lake Oconee, and nearby Greensboro, Madison and Milledgeville. See all service areas.

Boiler repair questions and answers

25 common questions, answered by Eatonton Plumber Pro, a Georgia master licensed plumbing company (MP210274). Last updated November 10, 2026.

Why is my boiler losing pressure?

Pressure loss usually means a leak somewhere in the system or a relief valve that is letting water out. We track it down and repair it.

Why do my pipes bang when the heat comes on?

Air in the lines or a circulator problem is a common cause. Bleeding the system and checking the pump often fixes it.

Do you service the burner and controls?

We focus on the water side of the boiler: pumps, valves, tanks and piping. For burner and control issues, we can tell you what we find.

What is a hot water boiler?

A hot water boiler heats water and circulates it through pipes to baseboards, radiators or radiant floors to warm a home. Because it moves water through piping, it is as much a plumbing system as a heating system.

What pressure should my boiler run at?

Many residential hot water boilers run roughly 12 to 15 psi when cold and somewhat higher when hot, but the right range depends on the system and the height of the building. Check the manufacturer's guidance, or call us.

Why do I keep having to add water to my boiler?

A system that keeps losing water has a leak, a relief valve that is discharging, or an expansion tank problem. Adding water over and over brings in fresh oxygen and minerals that corrode the system, so it is worth finding the cause.

Why is one room cold when the boiler is running?

Air trapped in that zone, a stuck zone valve, a failed circulator or a balancing problem are common causes. Bleeding the radiators and checking the zone controls often brings the heat back.

What is a circulator pump?

The circulator pump moves hot water from the boiler through the heating loops. If it is noisy or stops moving water, rooms go cold even though the boiler is hot. We repair and replace circulators.

Why is my boiler relief valve dripping?

The relief valve opens when pressure gets too high, often because the expansion tank is waterlogged or the fill valve is overfilling the system. A worn valve can also drip. It is a safety device and should be checked promptly.

What does an expansion tank do on a boiler?

The expansion tank gives heated water room to expand. When it fails or fills with water, pressure spikes every time the boiler fires, which can make the relief valve discharge.

Can you repair radiant floor heating?

Yes. We troubleshoot the pumps, mixing valves and piping that radiant floors depend on, to bring back even heat in every zone.

What is a mixing valve on a boiler system?

A mixing valve blends hot boiler water with cooler return water to deliver the right temperature to a zone, such as a radiant floor. A failed mixing valve leaves rooms too hot or too cool.

Do you service combination systems that also make hot water?

Yes. Some homes around the lake use a combination system for heat and household hot water. We troubleshoot the plumbing side, including pumps, valves and piping.

How do I bleed a radiator?

With the system running, use a radiator key to slowly open the bleed valve until air hisses out and water appears, then close it. Keep a rag handy, and check the boiler pressure afterward, since bleeding can lower it.

Is a leaking boiler dangerous?

A small leak is usually not dangerous on its own, but it can damage floors, cause pressure loss and corrode the boiler. Water near electrical components is a hazard, so turn off the boiler if water reaches the controls and call us.

Should my boiler be serviced every year?

Yearly service before the heating season is a good habit. It catches leaks, failing pumps and pressure problems before the first cold night.

Do you work on boiler systems in commercial buildings?

We work on the water side of boiler systems, including pumps, valves, tanks, piping and backflow protection. Call us with the details of your system.

Why does my boiler make a gurgling sound?

Gurgling usually means there is air in the system. Bleeding air from radiators or high points in the piping often quiets it, and an automatic air vent can help keep it out.

Can a boiler leak cause damage under radiant floors?

A leak in tubing under a floor can show up as damp spots, pressure loss or warm wet areas. Finding it accurately before opening the floor saves cost, so call us if pressure keeps dropping with no visible leak.
