How To Fix a Leaking Hot Tub

Hot tub leaks happen, but they can be fixed easily. It is important to regularly check your hot tub for leaks and make necessary repairs before the problem gets worse.

The Cover Guy Safety Tip: Remember to power off the hot tub before making any repairs or adjustments.

Essential Tools and Materials
–     Basic tool set
–     Slice/Knife and Gate Valves
–     Pump Wet End Seal
–     Plumbing Tubing
–     Jet Bodies
–    Acrylic Spa Shell
–    Heater Assembly Manifold

Common Leak Sources

  1. The Pump. Many hot tub pumps leak. In most instances, the seal on the pump needs to be replaced or the union fittings need to be tightened. (Fittings become loose from repeat use). You can purchase a new pump seal online or at your local pool and hot tub supply store.
  2. Valves. All valves are at risk for leaks need to be checked regularly. The gasket on knife style valves can break easily and the valves on either side of the hot tub are also known to cause leaks. If one of your valves is leaking, it needs to be replaced immediately.
  3. The Heater. Hot tub heaters can leak. If you noticed your heater is leaking water, check the heater assembly manifold and replace any parts that are a source or potential source of the leak.
  4. The Shell. Leaks from the spa shell itself are uncommon since most hot tubs are made with durable fiberglass that is not easily broken. If the shell appears to be leaking, the source is most likely a jet or other attachment that is loose. If you have an actual shell leak, however, use PVC bonding products to seal the area.
  5. Connections. All hot tub connections, such as pipes, jets and gaskets, need to be checked regularly. Tighten all loose connections manually and seal those that are leaking. For example, a cracked pipe can be sealed with PVC sealing glue. Any failing gasket will need to be replaced.

The Leak Test
If you cannot identify the source of the leak, add a small amount of food coloring to the water and see where the food coloring is being pulled toward in the hot tub. Another option is to empty the tub slowly, noting the level at which the leaking stops. This is a good indicator of the possible location of the leak. Finally, if you cannot identify the source of the leak, call in a Hot tub repair specialist.
