Heises Plumbing evaluates suspected water leaks using diagnostic methods appropriate to the plumbing system and symptoms present. Depending on the situation, testing may include pressure testing, acoustic investigation, visual inspection, or other diagnostic methods to help determine the likely source of the leak.
Proper leak detection begins with an accurate assessment of system symptoms. Heises Plumbing uses appropriate diagnostic tools, which may include acoustic line locators, thermal imaging, or pressure testing to help locate hidden underground, slab, and wall pipe leaks while minimizing property disruption where possible.
Once the leak is located, all pipe repairs and replacements are installed to meet current California Plumbing Code standards using high-grade copper, PEX, and brass components to ensure long-term durability.
These symptoms can have several causes. A plumbing evaluation can help determine whether a leaking water line or plumbing component may be contributing to the problem.
Sudden increases in water costs without a change in usage habits.
Hearing water running when all fixtures and appliances are turned off.
Moisture or visible water stains appearing on walls, ceilings, or flooring.
Unusually warm spots on the floor which may indicate a hot water slab leak.
A noticeable drop in water pressure across multiple fixtures.
Persistent moldy or musty smells coming from walls, floors, or cabinets.
We consult with you to review the visible signs of water damage, meter readings, and other indicators of a potential leak.

Common questions about our professional services in San Francisco and the Peninsula.
Heise's Plumbing begins by evaluating the symptoms and accessible plumbing. Depending on the situation, technicians may use pressure testing, acoustic investigation, visual inspection, meter testing, or other diagnostic methods to help identify the likely source of a leak.
Not always. Some leaks can be investigated using non-invasive diagnostic methods, but certain situations may require access to walls, ceilings, floors, or other surfaces to confirm the source or complete repairs.
Possible signs include unexplained water usage, sounds of running water when fixtures are off, damp areas, water stains, reduced water pressure, musty odors, or recurring moisture. These symptoms can have multiple causes, so a plumbing evaluation can help determine whether a leak may be contributing to the problem.
Our technicians explain the findings and discuss appropriate service or repair options. The work that may be recommended depends on the location, condition, and accessibility of the affected plumbing.
