Leak detection in Waltham Cross

A letter about constant use leaves two things to settle: whose pipe it is, and where it leaks. For leak detection in Waltham Cross we work out both from the surface.

Waltham Cross sits at the southern tip of Hertfordshire on the edge of the Lea Valley, named after the Eleanor cross still standing in the town centre. Older terraced streets give way to interwar and post-war housing, with shops, flats and small business units mixed in.

Close to the county boundary, check which water company supplies you; the name is on your bill, and a letter from it is how many leaks first come to light. Some older terraces also share one supply pipe with next door, which changes how we test.

Typical work in Waltham Cross

A meter chamber shared by three terraced houses

The property

An interwar terrace with a short concrete front garden. Its meter shares a pavement chamber with two neighbours' meters, and the supply runs under the concrete to the hall.

The problem

A letter about constant use arrived, yet the meter the owner had been checking hardly moved. Nothing indoors was damp, and the toilets and taps were fine.

How we found it

Turning the indoor stop tap off and on showed which dial was really theirs, and it crept with the tap shut. The ground microphone peaked halfway along the concrete, where tracer gas seeping through a crack agreed.

The outcome

One small square of concrete was broken out at the mark. We repaired the pipe while there, quoted separately, and the owner sent the photographs and report to the supplier.

Gas pipework under a small business unit

The property

A single-storey unit on the edge of town, with gas pipework under its concrete floor, already isolated and made safe by the gas emergency service.

The problem

Staff had smelled gas and rightly rung the gas emergency service first. The gas engineer then needed the leak's position under the floor before breaking it out.

How we found it

The isolated pipework lost pressure under test. A hydrogen and nitrogen mix was then put in, and the detector found it rising at one point by the rear wall.

The outcome

Payment came in advance, as it can for businesses. The point was marked and photographed, ready for the registered gas engineer to carry out the repair.

Owners with the meter in the pavement

If the letter says water is passing constantly, close your indoor stop tap and watch the meter. Still moving means the leak lies between the two, usually outside.

Neighbours on a shared supply

Some older terraces share one supply pipe between two or more homes. Closing each stop tap in turn shows whether the loss is on the shared stretch.

Shops, units and small offices

A business water bill that jumps, or gas pipework made safe but not yet traced: we handle both. For a business, payment may be needed in advance.

Which water company is yours?

Start with the name printed on your water bill, or the supplier's own postcode search if you are unsure. Its letter about constant use means water is passing the meter with everything off. Its own pipes stop at the boundary or meter, and the length from there into your home is usually yours.

Letter to marked spot, in three steps

What we ask first

Have the letter to hand. Give us a rough distance from meter to stop tap, and say whether the supply is shared and whether this is a home or business.

Split the supply

Stop taps are closed one at a time while our engineer Charlie watches the meter. That shows whether the loss is inside, outside, or on a length two homes share.

Trace, confirm, mark

The leak is followed along the pipe with a ground microphone or tracer gas, checked with the other method, then marked and photographed for you to keep.

How we trace pipes in Waltham Cross

Acoustic listening

Under pressure, a split pipe hisses, and soil or concrete carries that noise up to the surface. Stepping the ground microphone along its route, we mark the loudest point.

Tracer gas

Where sound is faint, as on plastic pipe, a hydrogen and nitrogen mix goes in and the detector finds it breaking the surface over the leak. It also works on isolated gas pipework.

Pressure testing

Sealing a pipe and watching its pressure proves whether it leaks before any tracing. On gas pipework already made safe, it shows the gas engineer which section needs work.

Business premises and insurance

If you rent a shop or unit, the buildings cover may be your landlord's policy rather than yours, so check the lease and both policies before booking. Our report gives the location, methods, readings and photographs for whichever insurer handles it, and is yours once the visit has been settled in full.
