Alternating Pressure Mattress Repair Tips

How To Repair an Alternating Pressure Mattress At Home

If your alternating air mattress system is no longer maintaining air pressure (i.e. sinking, collapsing, bottoming out, no longer functioning), there are a variety of root causes that may be responsible. The below troubleshooting guide should be used to identify or narrow down the potential source of the problem in the system.

Alternating Mattress Systems can be broken down into 2 component systems:

1. Mattress (Air cells, tubing, cover.)

2. Pump (Air compressor unit, power cord.)

It is important to isolate the complaint to either one of these components to facilitate effective complaint device return and replacement. Trying a new or different pump on the system is the quickest way to identify the defective component system. 

Should switching the pump resolve the issue, return the original pump  for evaluation.  If the replacement pump does not correct the issue, continue to follow the troubleshooting steps below to isolate or resolve sources of air loss on the mattress.

Before you Begin

Make sure you Secure the CPR valves at the head of the mattress. If the CPR valve is open or loose the mattress cannot establish air pressure and will not inflate.

  1. Inspect the tubing along the length of the mattress.
  2. Look for any disconnected or loose tubes and secure them back into place.

Check the tubing for any cuts and tears.

Make sure to check the tubing in the mattress tail for tears. The mattress tail runs from the pump to the mattress and is largely covered by a fabric sheath. The sheath may hide tears in the tubing. Slide or roll the sheath down to inspect the entire length of the white tubing.

Make sure that the quick-connect plug is not loose.  This can be done by pushing the quick-connect down onto the tubing.

 Inspect the quick-connect plug for damage. Both white posts should be at equal heights, as in the above picture. The below picture is damaged.

  1. Check the Red/Yellow valves to see if they are broken or cracked. The pictures below show the proper orientation for each valve – the orientation is important as the Red/Yellow valves are one-way valves (only allow air-flow in one direction, from yellow to red) and improper orientation will prevent air flow to the cells positioned downstream of the valve.

Should the issue be found during the pre-inflation steps, a replacement part(s) will be sent or will need to be purchased, based on the warranty.

Inflation Checks:

  1. Once the connections have been checked, and no source(s) for leaking could be detected, connect the mattress to the pump.
  2. Turn on the pump. Set the weight/comfort setting to 400lb and/or Max and set the pump to Static mode. Allow the mattress 20-30 minutes to inflate.
  3. If the mattress does not inflate, the low pressure light is on, or applying weight to the inflated mattress results in the mattress bottoming out, skip to step 5.
  4. Lower the weight setting to approximately 160lbs and/or about ¼ of the way up the dial and set the pump to Alternating mode. Allow 15 minutes for the mattress to readjust to this setting. Place weight on the mattress.
  5. If the mattress maintains air pressure and the Low Pressure Light stays off, the issue was most likely resolved during the pre-inflation steps. The mattress system is considered operational.
  6. If the mattress does not maintain air pressure, continue to step 5.

#5 Inspect Air Cells For Damage

  1. Small/pinhole/non-obvious leaks can be detected applying soapy water along the seam and tubing of the air cells. A leak will be indicated by seeing a large quantity of bubbles forming rapidly. Leaks can also be detected by applying water to the back of your hand. By running the back of your hand along the tubing and seals, a leak will be indicated by feeling a sudden cold sensation from the air leaking out.

Should an issue be found with one of the air cells, replacement air cell(s) will be sent or will need to be purchased (based on the warranty).

If the mattress continues to not inflate, despite following this troubleshooting guide, the mattress may need to be replaced.
