How to Drain a California King Waterbed

Use a Faucet Adapter

• 1

  Strip the sheets and mattress pad from the bed. Pull the valve cover out of the mattress and attach a garden hose to the valve.

• 2

  Connect the other end of the garden hose to a water bed faucet adapter, and attach the adapter to a sink faucet.

• 3

  Turn the adapter valve to the "up" position and turn the water on.

• 4

  Turn the valve to the "down" position and keep the water running. Allow the bed to drain completely, which may take three to four hours.

Use a Garden Hose

• 5

  Strip the sheets and mattress pad from the bed. Pull the valve cover out of the mattress and attach a garden hose to the valve.

• 6

  Connect the hose to an outdoor faucet placed lower than the bed.

• 7

  Turn the water on for 15 seconds, turn it off and remove the hose from the faucet. Allow the water to drain completely from the bed via the hose.
