Low-Water Cutoff Service in San Augustine, TX
The low-water cutoff shuts the burner off if water in the boiler drops too low. Firing a dry boiler can crack it, so this safety device needs to work every time.
There are two common types. Float type cutoffs on steam boilers need regular blowdown: you open the drain on the cutoff while the boiler runs to flush sediment out of the float chamber. Probe type cutoffs need the probe pulled and cleaned, since scale on the probe can fool it.
On hot water systems, a low-water cutoff often appears where the boiler sits above the radiation, and it trips when a leak or an air pocket drops the level.
Reliable Boiler Service connects San Augustine, TX homeowners with technicians who test the cutoff by lowering the water and watching the burner stop, clean or replace probes and floats, and show you how to do the blowdown yourself.
