Dennis’s concern about a crack at one of the spa jets leading to water leakage is a scenario many spa owners might encounter. This situation underscores the complexity of spa structure and the necessity for a meticulous approach to repair. While the outer aesthetic layer of a spa, typically made of acrylic, can indeed crack, it’s the underlying layers that play a pivotal role in ensuring water containment and structural integrity.

Understanding Spa Construction

Spas are constructed with a multi-layer approach to balance aesthetics with durability. The visible layer is made of acrylic for its appealing finish and is relatively thin, especially at the bottom of the spa where it can be between 0.020″ and 0.030″ thick. Beneath this, a layer of polyester resin reinforced with chopped fiberglass strands (FRP) provides the necessary strength. An additional layer of high-density polyurethane foam is often applied for insulation purposes. This construction method ensures that even if the acrylic layer cracks, the FRP layer typically remains intact, preventing water leaks.

Addressing the Crack

The crack Dennis observed at the spa jet does not necessarily mean that the spa will leak water, thanks to the FRP layer. However, water could potentially find a path through the jet’s assembly, which is why silicone sealants are commonly used to seal these points during assembly. To repair the crack in the acrylic layer without needing to remove the jet, the granite repair kit offered by Multi-Tech Products is an effective solution. This kit is specifically designed for such purposes, providing both the materials and the procedure needed for a successful repair.

Jet Removal and Repair

Removing a spa jet can be complex due to its tight anchoring and integration into the spa’s structure. If the repair necessitates jet removal, or if there’s a suspicion that the plumbing might be the source of a leak, consulting with a spa maintenance expert or the manufacturer is advisable. They can offer guidance on jet removal without compromising the spa’s integrity or advise on locating and fixing any plumbing leaks.

Conclusion

Cracks near spa jets can be concerning, but understanding the spa’s construction and the layers involved helps in addressing the issue effectively. While the aesthetic damage can be repaired with the right kit, ensuring the spa’s functionality and water-tightness might require professional input, especially when dealing with the intricate plumbing system. Dennis’s experience serves as a reminder of the importance of regular spa maintenance and the value of using specialized repair products designed for the unique challenges of spa repair.
