Service for leak in basement. Inspected and determined that the leak was coming from an upstairs steam radiator valve. The valve was wrapped with paper towels from when it was installed many years ago. There was not leak at this time. The packing nut on the valve was slightly tightened. The wood u set the valve was wet and rotted which showed that this small leak has been present over time. Estimate was provided for replacement of the steam radiator valve and 1/8†air valve. Manager on location will keep an eye on condition and schedule replacement if leak returns. Owner authorized Folkes office to charge credit card on file for diagnostic fee.
