Plumbing Antifreeze NT330
Hood Chemical non-toxic Plumbing Antifreeze NT330 has been specifically formulated to protect and prevent freeze damage to drains and fresh water lines in septic systems, boats, recreational vehicles, seasonal homes, swimming pool filtration and heating systems.
Our Plumbing Antifreeze NT330 is a mixture of propylene glycol, alcohols and water. It is completely non-toxic and if used as directed, it is not harmful to the environment.
Plumbing Antifreeze NT330 does not have a definite freeze point but will turn thick and viscous as the temperature drops and will not expand as water does. For this reason it is correct to refer to burst protection rather than freeze point. When used undiluted, Hood Chemical formula 0 provides burst protection down to - 51 C Care should be taken to make sure as much water as possible is drained from the plumbing system before adding Plumbing Antifreeze NT330. Dilution caused by water remaining in traps and pipes will reduce the level of burst protection.
