Update , the leak was on the fitting on the pump side of shut off valve where the fluid exits the tank. The solder had busted again. I took a short piece of heater hose put it over the fittings and clamped it at both ends. Leak is stopped . It also gives the entire manifold a little flex. This is the 3rd time in 4 years the solder has broke. Hoping the flex in the system will eliminate breakage. Now to replace the recirculating pump for the preheat it has shorted out due to the leaking fluid.
