Scuba Tank Maintenance
Proper diver weighting
Always lay tanks on their side before leaving them unattended. If you store your tanks in an upright position, be sure to secure them to prevent them from tipping over.
Rinsing & Storing Scuba Tanks
Like all gear, tanks should be rinsed with fresh water after every diving day. This prevents corrosion from forming on the cylinder and valve. If the cylinder has a plastic or rubber tank boot on the bottom, remove it on occasion and clean the bottom.

Water is a tank's enemy, so you never want it to enter the inside. To prevent moisture from entering the tank, always store it with at least 200 psi of pressure.

Tanks are heavy and can cause damage if tipped over. So when storing or hauling your tanks, either lay them down or secure them so they cannot tip over.

Heat increases the tank's internal pressure, so store them away from sources of heat. An increase in temperature can cause the burst disk to rupture.
