Bathroom Leak Detection in Ipswich

Symptoms

The owner of a flat in Ipswich had been contacted by their water authority advising of a suspected leak on the property. A plumber had already attended and confirmed through a meter isolation test that the loss was occurring internally, with no visible or audible signs pointing to the source.

Bathroom leak detection was the logical next step to identify where water was escaping without causing visible damage.

The flat comprises two bathrooms and a kitchen, with an unvented indirect hot water cylinder located near the internal stopcock. Because the customer has no access to the external meter, the investigation was limited to within the flat itself.

All pipework is routed above floor level and behind plasterboard, which ruled out the floor as an obvious area of concern but introduced concealed wall voids as a potential problem zone.

Methods Used

The investigation began with a thorough visual inspection of all taps and toilets across both bathrooms and the kitchen. Video evidence was captured of the toilet flushing valve in the main bathroom, which was found to be continuously running into the pan.

That toilet was isolated before pressure testing began, to ensure it did not interfere with results.

Pressure tests were applied to both the hot and cold feed pipework via the washing machine valve at the kitchen sink unit, with each system holding 40psi for one hour and passing. An endoscope camera was used to inspect concealed areas behind plasterboard where direct visual access was not possible.

Bathroom leak detection of this kind — covering both the pipe systems and the visible sanitary fittings — allowed the source to be identified without destructive investigation.

Investigation Process

1. 1
   Initial Visual Inspection

   A thorough visual check was carried out across all taps and toilets in both bathrooms and the kitchen. The main bathroom toilet was observed to be continuously passing water from the cistern into the pan.

2. 2
   Video Evidence Captured

   Video footage was recorded confirming the continuous flow of water through the toilet flushing valve. This provided clear documentation of the fault.

3. 3
   Toilet Isolated

   The main bathroom toilet was isolated at this stage to remove its contribution to water loss and allow accurate pressure testing of the pipework.

4. 4
   Pressure Test Kit Connected

   A pressure test kit was connected to the washing machine valve at the kitchen sink unit to test the internal hot and cold feed pipework.

5. 5
   Hot Feed Pressure Test

   The internal hot feed was tested at 40psi for one hour. The system held pressure throughout and passed.

6. 6
   Cold Feed Pressure Test

   The internal cold feed was similarly tested at 40psi for one hour. The system held pressure throughout and passed.

7. 7
   Endoscope Camera Inspection

   An endoscope camera was used to inspect concealed areas behind plasterboard. No further issues were identified in these areas.

8. 8
   Findings Communicated to Customer

   The customer was fully informed of the results. They requested the toilet remain isolated and confirmed they would arrange its repair independently.

Result & Outcome

The source of the water loss at this property in Ipswich was identified as the flushing valve on the main bathroom toilet cistern, which was continuously passing water into the pan. This was confirmed through direct visual inspection and video evidence, with no pressure loss recorded on either the hot or cold feed pipework during testing.

Pressure tests on both the internal hot and cold feeds held at 40psi for one hour without any drop, ruling out leaks within the concealed pipework. The endoscope camera inspection of areas behind plasterboard found nothing of concern. The outcome of this bathroom leak detection exercise was clear: the pipe systems are intact and the fault is confined to a single sanitary fitting.

With the toilet isolated, the water loss has been stopped in the short term. The customer has been advised of the findings and has chosen to arrange the toilet repair independently. No structural or pipework investigation is required — the repair needed is straightforward replacement or servicing of the flushing valve.
