Waterbed Maintenance

Why maintain your waterbed?

A well-maintained waterbed lasts longer, sleeps better, and costs less to run. Regular care keeps the vinyl supple, prevents odours, stops air build-up and waves, and protects your heater and base.

Quick Care Checklist (save this)

  • Add waterbed conditioner every 6 months (standard) or 12 months (long-life).
  • Wipe vinyl monthly with a vinyl cleaner or mild soapy water; dry thoroughly.
  • Bleed air whenever you hear sloshing/feel waves (often after refills).
  • Check for leaks monthly—especially seams, corners, and valve.
  • Inspect heater seasonally—confirm set temp and that it cycles normally.
  • Protect the liner—make sure it’s sitting correctly and not creased.
  • Wash the cover/topper as per label to reduce dust and moisture.

The Right Conditioner (and why it matters)

Waterbed conditioner:

  • Inhibits algae and bacterial growth (prevents smell/cloudy water).
  • Lubricates the vinyl from the inside (extends bladder life).
  • Reduces trapped air formation.

How much?

  • 1 bottle per bladder (king/queen often have two).
  • Pour into the filler cap, top up with water if needed, then bleed air.

How to Bleed Air (2–3 minutes)

  1. Unzip the cover to access the valve.
  2. Open the valve and insert the bleeder pump or hose adapter.
  3. Gently pump/squeeze until air stops gurgling and water reaches the neck.
  4. Close the valve firmly; wipe any moisture; refit the cap.
  5. Smooth the surface from edges towards the valve to push tiny bubbles out.

Tip: If air returns quickly, you may be under-filled or overdue for conditioner.


Setting the Correct Water Level

  • Lie on the bed; your hips should not bottom out on the base.
  • A good starting point is the factory fill line (if marked) or until the corners are just rounded, not tight.
  • Add/remove in 5–10 L steps and re-check after 24 hours.

Temperature & Heater Guide

  • Typical comfort: 27–29 °C (cooler for summer, warmer for winter).
  • Give temperature changes 12–24 hours to stabilise.
  • The heater pad must sit flat under the bladder with no folds.
  • If the heater trips often, or runs constantly, contact service—do not keep cycling power.

Cleaning the Vinyl & Surrounds

  • Monthly: wipe the bladder and safety liner with a vinyl cleaner or mild dish soap solution; dry completely.
  • Do not use solvents, alcohol, or abrasive cleaners.
  • Treat exterior timber with manufacturer-approved polish only (avoid overspray onto vinyl).

Draining & Refilling (move, deep clean, or replacing parts)

You’ll need: drain pump or utility pump, hose, towels.

  1. Turn off heater and let water cool to room temp (to protect vinyl).
  2. Insert pump at the valve and run hose to a suitable drain point.
  3. As water lowers, support baffles (if present) by smoothing towards the pump to prevent creasing.
  4. Once empty, inspect liner/base and wipe clean.
  5. Refill slowly, checking corners and liner placement; stop at your normal level.
  6. Add conditioner, bleed air, and wait 12–24 hours before heating to full temp.

Leak Action Plan (stay calm)

  • Unplug the heater.
  • Identify the source (valve, seam, puncture).
  • Contain with towels; the safety liner should hold water—do not pierce it.
  • For small punctures: dry the area, apply a vinyl patch kit, press firmly, cure as directed.
  • Refill just enough to test. If seams are involved or the patch won’t hold, call Shire Waterbeds for repair/replacement.
