Saved another 22 year old cooling system from certain boneyard death.
The sump was leaking from several golf ball size corrosion holes before a stainless steel liner was installed a few years ago. The problem with the stainless steel liner was the support posts weren’t removed beforehand so the liner could be properly installed. This left these support posts to continue to rust and opened the door to more leaks.
We came in, vapor blasted, pressure washed then sprayed with a beautiful Polyurea 60-80 mils thick coating. This sump now will outlast the coil bundle’s life span.
