Low Water Cut Offs

Low Water Cut Offs (LWCO’s) monitor boiler water level and turn off the oil or gas or electric heat source to the heating boiler should water level drop too low in the steam boiler, this important safety device prevents explosion or damage to the boiler should the system lose its water. Manufacturers require LWCO’s to be flushed to remove sediment that could prevent the cutoff from working. If the low water cutoff valve is not flushed often enough, the residue of solid debris (minerals, rust, dirt) can clog the low water cutoff valve so that it will stop working and could fail to sense an unsafe low-water condition in the heating boiler.

Low Water Cut Off Maintenance

To minimize the risk of overheating or melting the boiler with a “dry fire” many insurance companies require that the Low-Water-Cut-Off be dismantled, cleaned and reassembled on an annual basis to reduce costly repairs and extend the life of your Low-Water-Cut-Off Controls. We will dismantle the existing Low-Water-Cut-Off; clean float, bowl; inspect linkage and test switches; re-assemble and test operation. Price includes (2) LWCOs per boiler.
