Are Stainless Tanks all stainless steel?
Only 1 or 2 items in the tank are not stainless steel. One is the tank overflow, which is a molded PVC fitting. Our tanks larger than 3 meters in diameter have a PVC center prop. Some customers insist to have this center prop replaced with a stainless steel prop to ensure there is no contact of water with plastic at all. The tanks are sealed (like all steel rain water tanks) with potable water approved silicon.
