Pool Service Miami: Understanding Spa Leaks

Pool Service Miami: Understanding Spa Leaks

Leak detection and repair were outlined in more detail in the previous chapter, but it should be noted that spas are far more prone to leak problems than any pool I have ever seen. In addition to the likely leak locations already detailed, many fiber-glass and acrylics spas leak at the light fixture, skimmer assembly, or jets. Spas are designed to vibrate with turbulent water and bend under heavy bather loads, so these additions are subject to loosening and leaks.

Conducting a dye test (described in chapter 10) is easier on a spa than a pool because you can test virtually every corner without getting very wet. Also, the dye remains close to your eye level for easier observation. So unless you have trouble finding a leak, I would not use the drain-down test but move directly to the dye test when troubleshooting spa leaks. Most Pool Companies Miami can help you with this if you run into issues or do not have the experience.

If the jets are found to be leaking around the faceplate, they probably need to be tightened. Use your jet wrench to check each fitting. Time, harsh chemicals, and heat can deteriorate the gasket between the jet body and throat, so tightening might not seal the leak. Unfortunately, you can’t usually replace gaskets. If you remove the throat, the jet body behind the spa will invariably shift slightly, making realignment for reassembly impossible. If you can access the jet body, replacement of the gasket is possible.

Always remember to contact Pool Service Miami if you have specific questions regarding Leaks. We are always happy to help.

If the gasket seal is found to be leaking, try draining the water level down below the jets and unscrew the throat slightly. Allow the area to dry completely. If the gasket is brittle and/or extremely deteriorated, remove it. Tale a new gasket and cut it along one side so you can open it and slip it around the jet throat. Obviously, the place where you cut the gasket will not seal when you tighten the throat down, so fill the gap with silicone sealant, then tighten. Wipe the excess sealant that oozes out as you tighten away from the face of the jet. Wipe in an even, steady motion, forcing the material into the seal area and smoothing it over the joint of the jet face and spa wall. The objective is to form a watertight seal and thoroughly cover the work with the sealant. Allow the work to dry completely before refilling the spa and dye testing again.

Similarly, the integrity of other joints, such as the skimmer, drains, and light fixtures, is often compromised. In each case, tighten whatever you can and then seal the entire assembly with silicone sealant. These seals will often leak again as the silicone shrinks from constant temperature extremes and harsh chemicals, but this provides and inexpensive and quick way to extend the life of the spa. Of course, the best repair is to completely disassemble the leaking component and replace its gasket or the component itself. But if the spa installation does not allow than an option, silicone is your best bet.

If you have made there repairs in numerous places in a spa, we recommend a full overhaul. In this case, you remove enough of the deck and back-fill to expose the plumbing, replace the fittings and fixtures in the spa, then rebuild the assembly. This is best performed by an experience Miami Pool Service company since it requires more experience.
