Important to Know

Pinholes or rust may occur on stainless steel tanks in environments with high humidity, when salt is present or if condensation remains on tank without being routinely wiped down. If your system will be exposed to one of these factors or you are unable to perform the needed maintenance, we recommend a fiberglass tank.
