Heater Replacement Tips:

Important Things To NOTE:

How old is your safety Liner? Over 5 years of age? Check for common problems: Torn, broke down along the sides or corners, is there a hole(s) in it? If you said yes you are in the market to replace your liner. You will need to consider a new soft side waterbed liner found here.


Remember it does what it says. It is a safety liner and is your final and last safety net in the case of a leak and should be swapped out for a new one. Home repair is expensive, liners are not. Do not play Russian Roulette and risk home damage, replace the worn liner.


When refilling your water mattress do not forget to exhaust all the air out by burping it. Burping your air pockets out of the water bladder reduces loud and obnoxious sloshing noise and makes the bed more comfy and cozy all night long.

Prevent waterbed odor by adding waterbed treatment. The conditioner can be purchased here.
