Boiler leak?
 

I have a oil weil mclain boiler during the storm we lost power so boiler did not work.I recently noticed that there is a slight leak on left side of boiler on floor when I run my hand along the bottom edge of the boiler sometimes there is water and sometimes not could this be condensation from the boiler from being turned on and off and is it normal.Any advise or explanation would be appreciated.

has one procedure for one type of pressure test.

If you find a leak, there may be some type of StopLeak chemical product for this.
