Low-Water Cutoff Service in South Londonderry, VT

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 South Londonderry, VT 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.

Low-Water Cutoff Service FAQs

Frequently asked questions about Low-Water Cutoff Service

Questions we hear most often about Low-Water Cutoff Service in South Londonderry, VT.

Talk to a real person
What pressure should my boiler run at in South Londonderry, VT?
Most residential hot water boilers sit around 12 to 15 psi when cold and stay under 30 psi when hot. Steam boilers are different and run at a fraction of a pound.
Do condensing boilers work with old cast iron radiators?
They can, but they only condense when return water comes back cool. Outdoor reset control and properly sized radiators make the difference.
Why are my radiators cold at the top?
Air is trapped in them. Bleed each radiator with a radiator key until water runs steadily, then check the boiler pressure and top it up if needed.
How often should a boiler be serviced?
Once a year, ideally before the heating season. Steam boilers with a float type low-water cutoff also need regular blowdown through the winter.
How do I know if my boiler is the right size?
A room-by-room heat loss calculation is the only real answer. Boilers that short cycle on mild days are often oversized for the house.
