Which leaks do engineers trace in Llangynidr?
Describe where water appears, how the meter behaves and whether the heating pressure is falling so ADI Leak Detection can plan the relevant checks.
Detached houses make up nearly three-quarters of Llangynidr’s built-up-area homes in Census 2021, with semi-detached houses forming most of the remainder. The village’s older setting includes stone-walled wash lanes and the stepped lane beside the bridge on Mill Road. When describing your own supply, give the present meter and stop-tap locations and any known pipe route.
Access through a garden or over steps may need arranging before testing. Inside the home, moisture and thermal checks can help locate water concealed beneath finishes.
For a Llangynidr supply that appears to lose water outside, explain where wet ground lies in relation to the meter and house. Mention any separate building on the connection. Tracer gas or acoustic testing can help narrow the suspected underground escape.
