Things You Will Absolutely Need


A clean hose is used for draining your mattress. Old hoses or used garden hoses can introduce bacteria and other things into the mattress. A 25 foot hose may not reach far enough. You may wish to pre-measure the hose length needed.


Faucet Connector / Adapter allows connecting the Hose or Venturi Pump to indoor sink.

Waterbed Conditioner should be poured into mattress if it is to be stored for a period of time.

If moving right away you will need to have this so you can set your bed up right away.

If you don't have everything you see above, you are not ready to drain your mattress.

Optional Items
