How can I tell whether a shower leak is plumbing or waterproofing?
The timing and controlled testing of supply fittings, wastes and wet-area surfaces can help narrow the source. Water below a shower does not by itself prove which system has failed.
Why does the cupboard under my sink stay damp?
Possible sources include the mixer, flexible connectors, waste, trap, appliance hoses or water tracking from the sink edge. Dry the area and observe when moisture returns.
Should new bathroom plumbing be tested before tiling?
Altered or new pipework should be checked before finishes close access. Recording concealed routes can also help future maintenance.
Is appliance plumbing part of a normal sink repair?
Not automatically. Dishwasher or appliance connections should be identified separately so the scope states which valves, hoses and wastes are included.
