Waterbed Drain & Fill Kit, How to Use One.

There are several things that you must know when you have a waterbed. The first, is make sure that you never jump around on the bed, and the second is to learn how to properly drain your waterbed using a waterbed drain and fill kit and following the instructions. Draining your waterbed isn’t very hard; however, you must ensure that you take special care while you are draining your bed or you can ruin the baffling system or end up with a mattress that is very heavy and not totally drained.
Make sure before draining your waterbed mattress that you unplug the heater while you are draining your waterbed. Actually, the only time that your waterbed heater should ever be turned on is when the bed is filled completely with water.

Drain and Fill Kit Instructions
You first need to remove the cap and plug in order to burp all air bubbles from the waterbed mattress. Then replace the insert plug. Using a drain and fill kit which is available at any local waterbed store, remove the faucet aerator, and attach the faucet adapter to a sink. Next attach the Venturi Pump to the faucet adapter. Turn the bell shaped bottom piece of the Venturi Pump to the marked drain position.  You will then connect the waterbed mattress adapter onto the male end of the garden hose. Remove the plug insert carefully and attach the mattress adapter making sure not to let any air reenter the mattress valve and that the fitting is tight and submerged into the water.
Before starting the draining process if you know you have a sluggish or slow drain, you could experience an overflow. If this is the case you may want to play it safe, and attach the Venturi Pump to an outside faucet letting the water drain outdoors. After you have all of your connections in place, turn on the water to full power. The pressure of the water being forced through the restrictive hole and out the bell housing shaped fitting creates suction. This suction is called the Venturi effect. The suction is not only important to get out all of the water but, if you have a baffled, fiber, or foam insert to reduce wave motion, it can keep you from ruining a mattress. Let the mattress drain until vacuumed down and completely flat, this will hold the wave control system stationary and in place.
HINTS:
Be sure to use a garden hose that measures 50 feet or less and also that the washers for garden/utility hose are placed in all of the female connections. (Pump, Garden Hose, and Mattress Adapter. The components included in a drain and fill kit (Venturi Pump, Mattress Adapter, Faucet Adapter, and Washers) Questions of problems contact a waterbed store.

I recently added water to my waterbed via the garden hose and now my waterbed smells musty. What to do?

Drain the bed and start over. This time use water from a faucet that you would drink from. I also keep the hose that I use on my waterbed separate in the garage from the garden hoses. Because of my precautioins, I have never had a problem with bad water. Oh, another thing. Before attaching your hose hookup let the later run through the hose to clear out any bugs that have found their home there.

All really good advice Tracey. I would only ad that flushing the hose and letting the water run for a few minutes helps flush out bacteria that lead to odor related issues. Thanks for the tips!
