## Questions & Answers

**Q: Are they stackable?**
A: It is recommended to not place anything on the tanks, if you need to stack the tanks you will need a weight bearing shelf between them.

A: A shower head, some plumbing, a hot water heater, an accumulator, a vent, a fill, a shut off, a drain and some soap. Good luck.

**Q: can this be stood upright?**
A: Tank can be placed on any side.
Place tank on level surface and brace to prevent tank from moving during transit.
