Located in NYC
I currently have a Weil Mclain Gas Hot water boiler (CG5SPDN about 15 years old) 140k btu, with 30 gal indirect hot water tank. There is a little water dripping on the flame, a national grid service person told me that we have a leak in the boiler.
He suggests that we need a new boiler. Any suggestions on course of action, including recommendation for plumber to install new boiler and cost range.
It has been suggested that I try a product like Boiler Solder (Powdered Stop Leak) any thoughts on this.
