Heating Leak Detection in Greater Vancouver – How ROMA

Heating Leak Detection in Greater Vancouver

A leaking heating system rarely announces itself. Often the only clue is a boiler that keeps losing pressure, a faint damp smell, or a stain that slowly spreads near a pipe or radiator. Left alone, even a small heating leak causes corrosion, water damage, and repeated pressure loss that can shut your boiler down on the coldest night of the year. ROMA Heating & Cooling provides heating-system leak detection and repair across Greater Vancouver, tracing leaks in boilers, hydronic loops, radiators, and in-floor radiant systems since 1999. Our gas-licensed (TSBC) technicians find the source first, then fix it — rather than simply topping the system up and hoping.

Signs Your Heating System Is Leaking

• Pressure keeps dropping — you find yourself re-pressurising the boiler every few days or weeks.
• Damp patches or staining — on ceilings, walls, or floors near pipes, radiators, or the boiler.
• Visible drips or pooling — around fittings, valves, the pump, or the pressure-relief discharge pipe.
• Rust or limescale deposits — dried mineral or rust marks at a joint are the fingerprint of a slow weep.
• Cold spots or weak heating — lost system water reduces circulation and heat output.
• Musty smell or unexplained humidity — a classic sign of a hidden leak under floors or behind walls.
• Discoloured or warped flooring — common above a slow radiant or hydronic-loop leak.

Where Heating Leaks Usually Start

How ROMA Detects a Heating Leak

Finding a leak you cannot see takes a systematic approach rather than guesswork or tearing out drywall and floors at random:

1. System pressure test — we confirm the system is genuinely losing water and how fast, which rules a waterlogged expansion vessel in or out before we go further.
2. Visual and component inspection — we check the boiler, pump, valves, radiators, PRV discharge, and accessible joints for weeps and tell-tale staining.
3. Isolation testing — we isolate zones and loops to narrow the leak to one section of the system, which is essential for hidden hydronic and radiant leaks.
4. Leak tracing — for concealed leaks we use targeted tracing methods to pinpoint the location before opening anything up.

This staged process means we open the smallest possible area and repair the actual source — not just keep refilling a system that will only lose pressure again.

We Repair the Leak, Not Just Find It

Once the source is located, our technicians complete the repair: replacing failed fittings, radiator and zone valves, pump seals, a waterlogged expansion vessel, or a corroded section of pipe. We then re-pressurise the system to the correct level, bleed trapped air from radiators and high points, and confirm it holds steady pressure before we leave — so you are not back to topping it up next week. Where corrosion or sludge is the underlying cause, we can also advise on a system flush and inhibitor to protect the repair and the rest of the system.

Boilers, Hydronic and In-Floor Radiant

We trace and repair leaks across combi and system boilers, baseboard hydronic heating, and in-floor radiant systems. Radiant and concealed hydronic leaks in particular benefit from our isolation-and-trace method, which keeps disruption to your floors and finishes to a minimum and avoids the cost of unnecessary exploratory work.

What Causes Heating Leaks in the First Place

Understanding why heating systems develop leaks helps explain our repair recommendations and how to prevent the next one:

• Internal corrosion — over years, oxygen and sludge in the system water corrode pipes, the pump, and the heat exchanger from the inside out; this is the most common root cause we find.
• Worn seals and glands — pump seals, radiator-valve glands, and gaskets harden and weep with age and heat cycling.
• Pressure stress — a waterlogged expansion vessel lets pressure spike when the system heats, pushing the relief valve open and stressing joints.
• Movement and vibration — pipes expanding and contracting, or a vibrating pump, gradually loosen compression and soldered joints.
• Freezing — pipework in unheated spaces or against exterior walls can freeze and split during a cold snap.

Because corrosion and sludge sit behind so many leaks, we often recommend a power-flush and a corrosion inhibitor after a repair, which protects both the new work and the rest of the system from the next failure.

The Cost of Ignoring a Heating Leak

A heating leak is one of those faults that only gets more expensive the longer it runs:

• Constant top-ups introduce fresh oxygenated water, which accelerates internal corrosion and sludge build-up.
• Persistent damp damages flooring, drywall, ceilings, and finishes, and can lead to mould.
• Low or fluctuating pressure makes the boiler lock out — often on the coldest night, when you need it most.
• A small, cheap weep left alone can become a burst joint or a failed component costing far more to put right.

Catching and fixing a leak early is almost always cheaper than the water damage and emergency repair that follow from leaving it.

Frequently Asked Questions

How do I know if my heating system is leaking?

Common signs are a boiler that keeps losing pressure and needs topping up, damp patches or staining near pipes, radiators, or the boiler, rust or limescale around fittings, a drop in heating performance, or the sound of dripping. Hydronic and in-floor systems sometimes leak with no visible water at all.

My boiler keeps losing pressure but I can’t see any water — why?

Pressure loss with no visible leak often means a very small joint or radiator-valve weep, a leak under the floor in a hydronic loop, or a waterlogged expansion vessel mimicking a leak. We pressure-test the system and trace it down rather than just topping it up.

Can you find a leak in an in-floor radiant heating system?

Yes. We isolate and pressure-test the loops and use leak-tracing methods to narrow down the location in radiant and hydronic systems, so the repair is targeted instead of opening up large areas of floor.

Is a heating leak urgent?

A small weep can often wait a short time, but ongoing leaks cause water damage, corrosion, and repeated pressure loss that can shut the boiler down in cold weather. Active leaking, or a boiler that won’t hold pressure, should be looked at right away.

Do you repair the leak as well as find it?

Yes. Once we locate the source we repair it — replacing fittings, valves, seals, an expansion vessel, or a section of pipe — then re-pressurise and test the system to confirm it holds before we leave.
