How to take care of your hot tub

Hot tubs can be a relaxing way to unwind, but they require regular maintenance to run smoothly. Here's what you need to know about cleaning and repairing your hot tub.

How to take care of your hot tub

Easy ways to clean your hot tub

  • Treat hot-tub water much as you would pool water, testing it and treating it with chemicals to maintain proper sanitation and the correct pH level. Keep leaves out of the water and leave the cover on when not in use.
  • Keep the motor and pump clean. Vacuum away any dust and spray with pump lubricant, which is available at pool stores. Clean or replace filters monthly.
  • Whenever you detect slime on the sides or bottom, drain the tub and scrub the inside with a mild bleach solution. Rinse the tub thoroughly before refilling.

Patch leaks in a wooden hot tub

Small leaks can occur if a gap opens between vertical wood staves. Dark spots near the gaps suggest a leak.

  • Use a putty knife to pack the gaps with cotton string, which swells and reseals the seam. If water has started dripping through the tub, the problem is more severe. Talk to the dealer immediately.

Diagnosing a mechanical problem

  • If the pump won't work, make sure that the switch to the pump is on.
  • See if the circuit breaker has tripped; if it has, and continues to do so after you reset it, call for service.
  • If an electric heater is broken, check the circuit breaker; then try turning off the power and tightening any loose wires leading to the thermostat.
  • If the water is heated by gas, make sure the gas shutoff valve is open and the pilot light is lit.

A warning

A hot tub is heavy: it holds 1,900 to 2,650 litres (500 to 700 gallons) of water and needs a sturdy foundation of crushed stone or concrete. To operate, a pump circulates water through a filter and then through a heater, which brings the water to about 38°C (100°F).

  • Be careful; sitting in very hot water for more than a few minutes may adversely affect the young, the elderly and people with medical conditions; if in doubt, ask your doctor is a hot tub is right for you.
