How To Drain A Waterbed With A Shop Vac? – The Complete Guide

Here are some steps to do this easily and safely.

1. Take Out All The Protective Covering From The Mattress​

  • A waterbed can be a great addition to your home, but it can also be a nightmare if it’s not properly drained. Don’t wait until there’s a major flood – take action now! 
  • The first step is to remove all the protective covering from the mattress. This includes the mattress cover, mattress pad, and any other covers.
  • Make sure to clean out any remaining water and debris before sealing it up again. 
  • Next, use a shop vac to suck up all the water and debris in the bed. This will help avoid a major flood down the road.

2. Ensure That Your Waterbed Heater Is Unplugged Before Draining The Bed

  • First, unplug the waterbed heater if it’s plugged in. 
  • Next, open one of the side panels (it should have a handle) and remove both clamps that hold down each end of the straps on either side of the bed frame assembly. Be sure to note the location of the drain hose as you remove the panel, as you’ll need it later. 
  • Finally, turn off all electrical sources – including the waterbed’s main power switch – and disconnect any hoses leading from the drain pipe. 
  • With one person holding down each end of the strap while someone holds onto the top clamp on the side panel, carefully pull the panel out as closely to the edge of the mattress as possible, making sure not to pinch cables or rip vinyl coverings.

3. Find The Fill And Drain Valve Of The Bed​

  • First, open up your shop vac as much as possible without dumping everything out. 
  • Next, place the intake tube over the fill valve opening on the waterbed frame. 
  • Hold down the release button until the machine starts to suck. When the machine becomes quiet, carefully remove the intake hose from the frame mark center vacuum line at the top. 
  • That’s it! Next, remove the cover over the pump by unscrewing two screws on each side of it. 
  • Finally, locate the power supply for the bed and turn it off. Disconnect all hoses from around the pump. Now you are ready to drain your waterbed!

Frequently Asked Questions

How do you remove water from a waterbed with a shop vac?

If your waterbed has been heavily wetted, it may be time to call in the professionals. This means that the mattress is saturated and unable to hold the weight of a person or animal. 

Professionals can use a waterbed dryer or the ULTRA wet method to remove the water. The manual way is by manually sucking all of the water out from under and around the mattress with a shop vac hose attachment. 

There are a few ways to drain waterbeds using a shop vac: the manual way, the ULTRA wet method, and the bed dryer. The bed dryer is pretty self explanatory – place your mattress on top of an air conditioning unit or inside out freezer for about 24 hours.

Does it matter if I remove the pump first or leave it in place and use the shop vac on top of it?

It always pays to remove the pump first before using the shop vac on top of it. This will minimize damage done and make sure that the vacuum is working as intended. 

If you leave the pump in place, make sure to open up all air vents and turn off the electricity before plugging in the shop vac.

Can I use my own vacuum cleaner instead, or would that be too dangerous to use near an electrical outlet and waterbed?

There is no definitive answer to this question as it depends on the specific vacuum cleaner you are using and the water bed you are draining. 

However, the safest way to proceed is to turn off all unnecessary appliances in the house before vacuuming, wear gloves and eye protection when working with the vacuum cleaner, and make sure that the power cord and plug are long enough so that you can reach all areas of the waterbed.

How much time will it take to drain my waterbed?

It will take about 30 minutes to drain your waterbed, depending on the size and shape of the mattress. 

After draining the mattress, it’s recommended to vacuum the entire mattress using a machine with a hose attachment.
