Record the water loss and conditions
Note the water level, time, recent use and whether the cover was on. Photograph the same reference point so changes are easier to compare. Look for visible water around the outside without reaching into electrical areas or removing panels.
Bathing, splash-out and evaporation complicate a level comparison. A wet patch does not identify the failed part, and water can travel before it becomes visible. Explain what you observed rather than naming a seal or pipe as the confirmed cause.
When to stop using the spa
Do not use the tub if water is near electrical equipment or the level is below the manufacturer's operating requirement. Follow safe shutdown guidance and contact a qualified professional. In freezing conditions, explain the loss of water and operation when requesting urgent advice; switching off a faulty tub does not resolve its freeze risk.
Prepare for a leak-detection visit
- Provide the spa model and whether it is built into a deck.
- Describe where access panels are blocked by steps or structures.
- Record whether loss seems associated with use or a particular cycle.
- List recent repairs, moves or winter closures.
- Keep photographs and level records together.
Ask what access the technician needs before moving anything. Obtain a separate price for removing or reinstating deck sections if necessary. An accessible diagnosis and a repair buried behind surrounding construction are different scopes of work.
What should the repair quote include?
Request the diagnosed location, proposed parts, labour, access work and the method for confirming the leak is resolved. Ask whether the quote includes refilling, water treatment and a return visit if loss continues. Check warranty coverage before authorizing work.
Can a bottle of leak sealer fix it?
Do not add an unapproved product to avoid diagnosis. Ask the spa manufacturer and repairer whether any proposed treatment is compatible and whether it changes warranty or later repair options.
Should I drain a leaking tub in winter?
Get model-specific professional advice promptly. Draining the shell can leave water in other components, so it is not automatically a safe winter-storage solution.
