Normal water tank, clean and free of patches. There are cracks in the neck only, and a 1.5-inch fitting is installed and sealed with a gasket. A reducer is also installed, as shown in the pictures. The tank's manufacturing is shown in the pictures, and I don't know its origin. I've had it for more than three years and bought it from Al-Gharabi in Riyadh for 1150 or 1200 riyals.
