About Tankless Gas Odor Leak Detection

Smelling the rotten-egg odor of mercaptan near an on-demand tankless water heater is an immediate emergency that demands rapid professional intervention. In Cornwall, Pennsylvania, loose gas union fittings, cracked flexible connectors, ruptured internal gas valve diaphragms, or failed combustion seals allow raw or unburned fuel to escape into living spaces. Gas leaks pose catastrophic fire, explosion, and asphyxiation hazards to building occupants. Our certified gas technicians use sensitive electronic combustible gas sniffers and non-corrosive bubble solutions to pinpoint the exact leak location. We shut off fuel supplies, rebuild gas joints, and verify 100% airtight integrity.

What Our Customers Say

Real reviews from homeowners and business owners we have helped.

Our Navien NPE-240A started beeping error code E003 on a freezing Tuesday morning. Marcus from TWH PRO's arrived within 40 minutes, tested the gas manifold pressure, cleaned the flame rod, and replaced a worn spark igniter on the spot. Having hot water back before our kids woke up was huge.

We went three days with lukewarm showers because our electric EcoSmart 27 kept tripping breakers. The technician tested the continuity of all three heating elements and found two had burned out from mineral scale. He swapped in genuine OEM canisters and descaled the chambers. Steaming showers are back.

Our restaurant dishwasher tripped a sanitation temperature alarm during Friday dinner service. TWH PRO's sent a commercial technician immediately. He cleared a clogged air intake screen on our cascaded Rinnai rack and re-calibrated the water servo in under an hour, saving our dinner service.
