"NYC Sewers helped us do hydro-excavation around utility lines in a new development project we did. We also hired them to clean and later maintain dry wells in our strip center that were flooding with heavy rains. Each time they were professional and knowledgeable and their prices were great compared to other companies we contacted."

Boiler Repair questions, answered by experts

If you go to turn it counterclockwise and it won’t turn anymore, it’s open. Like most other valves, you should be able to turn a radiator valve counterclockwise (to the left) to open it and clockwise (right) to close it. To close a radiator valve, turn it clockwise until you meet some resistance and can’t turn anymore, but do so carefully to avoid breaking the valve.

Leaks, pressure loss, air in the system, burner failures, and thermostat malfunctions are common problems that require professional repair.

If you hire a professional to replace your gas furnace’s thermocouple, you’ll usually pay between $150 and $250. Since thermocouples often fail due to a lack of maintenance, you may be able to avoid—or at least delay—a thermocouple replacement by taking good care of your furnace. This means scheduling annual furnace inspections, changing the filters at least once per season, and cleaning the burners occasionally.

Yes, it is OK to turn off some radiators, and you’ll save money on heating costs if you make it a regular habit to turn your radiators off in unused rooms that don’t need heat. That said, turn them back on when you need to heat your whole home instead of cranking up the dial on the ones you haven’t closed to compensate. The latter will result in higher heating costs and more wear and tear on your system.

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.
