Leak Detection in Bonnybridge
A working back boiler is about the best place in a house to hide a leak. It sits inside the fireplace with a gas fire fixed in front of it, its pipes go under the hearth or up inside the chimney breast, and it runs hot enough that a slow weep often dries before it can drip. In some of Bonnybridge's older terraces the back boiler is still there and still doing its job, and the signs of a leak on one are rarely a puddle. They are a rust streak at the foot of the fire surround, a white crust on a pipe, a stain on the breast that is warm to the touch, or a hearth tile that has started to lift. Finding which pipe it is starts with taking the fire off, not with opening the wall.

About Bonnybridge
Bonnybridge has older terraced houses where the heating was built round the fireplace, and in some of them the back boiler is still there behind the fire.
Bonnybridge grew along the Forth and Clyde Canal and the Bonny Water on the work of its foundries, Smith and Wellstood's stove works among them, and on the brick and fireclay works round about. Its older housing is mostly terraced, stone and brick rows near the centre and council built streets from the middle of the twentieth century, with newer estates since on the edges of town. The Antonine Wall runs along the south side, with the Roman fort at Rough Castle close by.
For a couple of decades, a back boiler was the usual way to heat a house with a chimney. A gas fire sat in front for the living room and a boiler sat in the fireplace opening behind it, heating the hot water and the radiators. Two pipes ran from the boiler up to a hot water cylinder, often in a cupboard directly above or beside the breast, and the radiator pipes left the fireplace under the hearth or through the floor beside it. Those pipes spend their lives against old brick and mortar in a warm, sooty space, which is hard on copper from the outside.
Heat is what makes these leaks hard to see. Water weeping from a joint on a hot pipe evaporates almost as fast as it escapes, and leaves behind what it was carrying: a white or green crust on the copper, or rust running down from a steel fitting. Only when the system cools, overnight or through a summer when the heating is off, does the same weep start to collect as water. So a back boiler leak often shows as a mark that appears in the morning and has gone by the evening, or as damp that turns up in June and not in January.

What We Do in Bonnybridge
Emergency Callouts
If water is running out of the fireplace, turn the boiler and the fire off at their controls, close the stopcock and call 07988 591331.
Boilers
A back boiler can weep from its own casing with age, and the boiler is checked as well as the pipes round it.
Drains
A rhone or downpipe overflowing at the foot of the chimney wall can wet the breast from outside, and that is ruled out before anything inside is opened.
Heating
Radiator pipes leaving the fireplace under the floor are traced with the heating on, so a warm leak shows against the cold boards.
Common Problems in Bonnybridge
Water in the fireplace opening behind the fire
The back boiler's own pipe connections sit inside the fireplace, hidden by the gas fire in front. A joint weeping there drips onto the floor of the opening, and the first sign is often a tide mark on the hearth, rust streaks at the foot of the surround, or a damp smell when the fire is on.
A stain on the breast at the height of the pipes
Where the two pipes to the cylinder run up inside the breast or in a chase cut into it, a leak shows as a patch on the plaster along their line. It stays the same in dry weather and wet, and it is often warmer than the wall round it after the hot water has been on.
A brown patch that comes back through every coat of paint
Coal fires left salts in the flue and the plaster, and those salts draw moisture out of the air. The patch darkens in muggy weather and fades on cold dry days, whatever the heating is doing. It is not a plumbing fault, and testing the pipes is the quickest way to prove it so the plaster can be dealt with properly.
A hearth tile lifting or a slab that has cracked
Radiator pipes often leave the back boiler underneath the hearth, bedded in the mortar below the slab. Copper buried like that corrodes from the outside, and water from a pinhole spreads under the slab until the tiles on top start to loosen or a crack opens. A warm patch on the hearth with the heating on, and the fire off, is the sign to mention.
Who You'll Get in Bonnybridge
Muhammad, who is Gas Safe registered and does a lot of the team's boiler repairs, takes the back boiler leaks, because the first step is often taking the gas fire off. That is gas work. The fire has to be disconnected, capped and refitted by a registered engineer, so it is not something to do yourself to have a look. With the fire off he can see the boiler's connections and the floor of the opening. Then the boiler goes on and the thermal camera goes over the breast, where the warm pipes show as lines and a leak shows as a bloom spreading from one of them. If nothing shows, he says so, and the chimney becomes the suspect.
Repair the Pipework, or Take the Back Boiler Out?
If the leak is on a joint or a length of pipe and the back boiler itself is sound and still serviced, repair the pipe. It is the smaller job by a distance, and nothing says a working back boiler has to go. If the boiler itself is weeping, from its casing or between its sections, it has usually reached the end, because a leak there is rarely a lasting repair and parts for some older models are hard to find. Replacing it means a new boiler somewhere else in the house and the pipes in the breast coming out, which ends that leak for good. If the leak is on a radiator pipe buried under the hearth, do not break the slab out to patch it: run a new pipe round the hearth under the floorboards instead and leave the old one capped, which is less work and does not disturb the fireplace.

“Our radiator pipe was bent and leaking. They answered straight away… Guy was here an hour later and he was wearing ID, very professional, patient and kind. We just got a new carpet in this room and he done an amazing job on getting little to no water on it. Couldn't recommend enough, price was reasonable.”

“We lost heating just in time for the coldest day of the year with a baby in the house… When I contacted them they were ready to dispatch that night. Fixed by the afternoon. Quoted that morning and no extra charges were added. Honestly cannot thank them enough.”

“As a small business owner, I needed a drainage company that could respond quickly. The team attended first thing in the morning, cleared the blocked drain and carried out a full CCTV survey. All documentation emailed across promptly. Professional, efficient and great value for money.”

Bonnybridge Questions
Very likely, and a slow one. A weep on a hot pipe dries almost as fast as it escapes, so what it leaves is the minerals that were in the water, as a white or greenish crust round a joint or a valve. It will not seal itself, and a weeping joint is usually a small repair if it is caught before it corrodes the pipe. Leave the gas fire in place and call 07988 591331 with where you saw it.
