Water storage tank repair

1200 gallon polyethylene plastic tank had its spout broken off. I prepped the area on tank for welding and plastic welded the spout back on. Its now stronger then when customer got it from factory.

Unlike tanks made of other materials, poly storage tanks require almost no maintenance. Steel tanks require external preventive care such as painting and internal inspection to determine weld integrity. Fiberglass also poses its own issues, like multiple layer construction and the sensitivity toward micro-cracking. Poly tanks eliminate the need for internal inspection for leaks and cracks.

Rotational-moulded polyethylene storage tanks are leak resistant because they are moulded, one-piece construction without seams. Steel tanks tend to develop pin leaks over time from rust and corrosion and have stress points at welds. The quality of fiberglass tanks and their resistance to leaks can vary widely due to the method of construction and quality of the manufacture. The seamless construction and superior inert qualities of polyethylene tanks means less chance of leaks.

In addition to reduced cost to transport, less error-prone installation and reduced need for maintenance, poly tanks can sometimes last longer than steel and fiberglass tanks.
