If you are having problems with your jetted tub leaking, you will need to know how to diagnose the problem before you can repair it. Generally speaking, jetted tubs are not that much different than regular bathtubs and showers in the areas where a leak can occur. Therefore, troubleshooting a jetted tub leak is not that difficult, and shouldn't take you more than a few minutes. This article will address some of the most common causes for leaks in jetted bathtubs and how to identify them.
Check for Cracks in the Tub
Because jetted bathtubs are usually used for recreational activities, they can sometimes be subject to abuse or horseplay. So, if your jetted bathtub is leaking, the first thing you should do is drain the tub and inspect the entire surface area of the jacuzzi or jetted tub for any cracks in the fiberglass. Depending on the severity of cracks in a jetted tub, you may or may not be able to repair them. If hairline cracks in the fiberglass of your jetted tub are causing problems, you may be able to plug the leak with some heavy duty epoxy. If that doesn't do the trick, you might want a plumber as he/she will usually have access to plumbing adhesives and cracks sealers that aren't easy to find at the local home improvement center.
Replace Old Plumber's Putty or Teflon Tape
If there are no cracks in the surface or basin of your jetted tub, you should start inspecting all the fittings for the floor drain and overflow drain assembly. Use a screwdriver to remove the cover plates of the drains and check the fittings for worn out or drying plumber's putty or old or decaying plumber's tape.
Many times, simply removing the drain fittings from your jet tub, and applying to new plumber's putty or wrapping some new plumber's Teflon tape around the fittings will help solve many of your leak problems.
Loose Faucet Handles and Connections
Just as you should check the fittings for the floor and overflow drains, you should also check the faucet connections as well. Remove the handles and cover plates from faucets and inspect the compression nuts used to attach the faucets to the water supply risers. Unscrew the compression nuts and wrap new Teflon tape around the fittings. Also check to make that sure that the rubber seals and gaskets used in the faucet are pliable and not worn, dry or cracked.
If you find worn rubber gaskets for washers in your faucets, replace them and see if that helps stop the leaking. If replacing the rubber gaskets and seals, or using new Teflon tape, does not fix your leaky faucets, you may need to purchase new ones and install them to stop the leaks in your jet tub.
When All Else Fails
If you've tried everything above, and your jetted tub is still leaking, then the problem is probably in the P-trap or main water supply lines going to your Jacuzzi. If this is the case, and you have access to those heights and lines, try installing new connection fittings or using new plumber's tape. If you don't have direct access to those pipes, you'll need to pull out your Jacuzzi and continue searching for the problem.
