Is fiberglass water tank toxic?

Fiberglass water tanks are generally harmless to the body, but it is necessary to ensure that their material meets relevant
hygiene requirements.

Firstly, from the perspective of material composition, fiberglass water tanks are a special material product composed of resin and fiberglass composites. This material itself does not contain harmful chemicals to the human body, so under normal use, fiberglass water tanks will not pose a direct threat to human health.

However, it should be noted that not all fiberglass water tanks can be used to store drinking water. Generally, fiberglass
water tank products with high low molecular weight content cannot be used for storing drinking water without being monitored and approved by the health monitoring department. This is because some low-quality fiberglass water tanks
may contain harmful chemicals to the human body, such as unreacted resin residues, additives, etc. These substances may dissolve during prolonged contact with water, polluting water quality and posing a potential threat to human health.
