NTI Flow Switch Replacement in Greater Vancouver
Genuine NTI flow switch, supplied and professionally installed by Technical Safety BC–licensed gas fitters. Never sold for DIY.
The Flow Switch on Your NTI Boiler
The flow switch proves adequate water flow through the heat exchanger before the boiler is allowed to fire, protecting the exchanger from dry-firing and overheating. A stuck switch causes no-heat or no-hot-water faults.
On NTI systems — including models such as Trinity Tft, Trinity Lx, TX Series — a failing flow switch often shows up as ignition failure or related symptoms. We diagnose it precisely and install the correct genuine NTI part.
