Leak detection in Thorpe St Andrew for heating and supply pipes

In Thorpe St Andrew's newer homes, trouble tends to show as a gauge that keeps dropping or tiles warm underfoot; nearer the river, the meter gives it away. Our engineer Charlie starts with whichever is moving.

Thorpe St Andrew runs along the north bank of the Yare on the eastern edge of Norwich. Its older part, near the river, has houses with timber floors, hot water cylinders and pipework altered over the years. To the east, newer streets stand on concrete floors.

In those newer homes, heating pipes and often underfloor heating loops are buried in screed, fed from a manifold in a cupboard. Most have a sealed heating system, so a leak there barely registers on the water meter. The boiler gauge is the clue, and that is where we start.

What a typical Thorpe job looks like

Falling pressure, but every underfloor loop held

The property

A detached house on the newer eastern side, with water-filled underfloor heating downstairs, a manifold in the utility cupboard and tiles throughout.

The problem

Every few days the gauge sank below one bar and had to be refilled, but no damp showed anywhere. The owners blamed a split floor loop.

How we found it

Each loop held at the manifold, so the loss lay on the flow pipe from the boiler. Thermal imaging traced it under the dining room once warm, and a pressure test agreed.

The outcome

Two dining room tiles were marked and photographed over the leak. Cutting in and joining the pipe was quoted separately, and the loops were left alone.

Loft tank refilling at night in an older house

The property

A house in the older part of Thorpe, with timber floors, a cold tank in the loft and a bathroom over the kitchen, its bath fed from the tank.

The problem

Anglian Water wrote about water passing the meter overnight, and the owners heard the loft tank refilling after bedtime. A faint mark had just appeared on the kitchen ceiling.

How we found it

Closing the tank's cold outlet to the bathroom stopped the meter. That pipe would not hold pressure, and moisture readings on the kitchen ceiling peaked beneath the tap end of the bath.

The outcome

Lifting the bathroom board at the mark showed a weeping joint on the bath's cold feed, remade during the visit, quoted separately, with our 3 month guarantee.

Thorpe households that ring us

Newer homes with heating in the floor

Pressure keeps sliding, the house looks dry, and a strip of tiles is oddly warm. We isolate loops and pipes until one fails to hold, then trace it from above.

People whose boiler has been cleared

An engineer has checked the boiler and blamed the pipes. Mention how often you refill and whether a sealant product has gone in, since both shape the testing.

Older houses with a supplier's letter

Anglian Water says water is passing your meter. With a loft tank and cylinder, closing the right valve shows which set of pipes to search.

Why the meter misses heating leaks

Thorpe St Andrew is supplied by Anglian Water, and its letters about constant use concern water passing your meter. A sealed heating system is filled once and topped up by hand, so its leaks barely register there. If Anglian Water has written, the supply pipe and hot water are the likelier suspects.

Starting from whichever dial is moving

1

Gauge or meter

A falling boiler gauge means the heating; a turning meter means the supply or the hot water. Knowing which, and how often you top up, decides the first test.

2

Close it down section by section

Loops are shut at the manifold, radiator branches at their valves, or a tank at its outlet, until the loss stops. The last section closed is the leaking one.

3

Camera first, then confirmation

Thermal imaging follows the warm pipe to the leak. Pressure testing or tracer gas then has to back it up before the spot is marked and photographed.

Tests for screed floors and older pipework

Thermal imaging

The heating has to run long enough for the floor to show the pipes clearly. Rugs and furniture hide them, so we may ask for those to be moved.

Pressure testing

Closing one loop or branch and watching a gauge shows whether it holds. In newer homes this soon separates floor loops from the flow and return pipes.

Tracer gas

Once a heating section is emptied, a hydrogen and nitrogen mix is pushed in. Wherever it leaks out, it works up through screed or boards to the detector.

Weigh the excess before you claim

The search price is agreed before you book, so you can set it against your policy excess before claiming. If a claim makes sense, check the trace and access section and whether approval is needed. The report gives the location, methods, readings and photographs; any opening up starts at the marked spot.

Common questions in Thorpe St Andrew

Usually a tile or two over the marked point, for the repair. We find the leaking loop at the manifold and the point along it from the surface. Pipes laid on insulation or a membrane give a softer picture, and we tell you on the day.

A sealed heating system uses hardly any mains water. It is topped up by hand through a filling loop, so a leak shows on the boiler gauge instead. Note the pressure before and after each top-up and the days between.

Usually, but say so at booking. Sealant can block small leaks for a while and stop some tests working properly, so tell us which product it was and about when it went in. We then plan the visit around it.

It buys a set block of searching, half a day or a whole day, agreed before you book and not reduced when the leak is found early. We pass on materials and parking at cost. No find, no fee on home water leaks does not cover central heating; full conditions are on our terms page.

A little. Timber floors let us listen through the boards, and many older houses still have a loft tank and cylinder, so the meter often shows a leak first. Newer homes on screed are tested from the boiler gauge instead.
