  • Pump Wet End Seal
  • Plumbing Tubing
  • Jet Bodies
  • Acrylic Spa Shell
  • Heater Assembly Manifold

 

  1. The hot tub pump
    Many hot tub pumps leak. Sometimes the problem can be the seal on the pump which can be replaced easily. Another fault can be with the union fittings. These can get loose from continual use, or even in shipment. To fix this, all you need to do is hand-tighten them and you will be fine. Also please note that it is a good idea to turn off the power to the hot tub before masking any repairs or adjustments.
  2. Hot Tub Valves
    All valves are at risk of leaking, and need to be checked regularly. The gasket on the knife style valves can easily break which will result in them leaking. Also there are some hot tubs that have valves on either side and are also a frequent cause of leaking. Valves need to be replaced right away if you see a leak in them.
  3. Hot Tub Heaters
    If you notice that your heater is leaking you need to check the heater assembly manifold and replace any parts that may be necessary in fixing a leak.
  4. Other Connections
    All connections need to be checked frequently for leaks. This includes all pipes and jets. Tighten loose ones, and seal those that are leaking and replace failing spa gaskets. Most connections can be tightened or sealed but leaking hot tub jets that have a failing gasket will need to be replaced. Cracked pipes can be sealed with PVC sealing glue.
  5. Spa Shell leaks
    Spa Shell leaks do not happen often as most hot tubs are made with very strong fibreglass that is not easily broken. On the other hand leaking may occur around the jests or other attachments due to lose thread or fitting.  If the shell of the hot tub has a leak, use PVC bonding products to seal.
  6. Other leaks
    If you cannot find where the leak is coming from, you can use this helpful method to find the leak. Add a small amount of food coloring to the water and look at where the food coloring is pulling toward in the tub. Another way is to completely empty the tub and keep checking the level at which leaking stops. This is a good indicator of the possible location of the leak.
    If you are having a hard time finding where the leak is coming from, or are not confident in finding the leak yourself it may be a good idea to call in a Hot tub repair specialist.
