A hot tub leak can be an unwelcome surprise, but don’t worry — in most cases, the issue isn’t as daunting as it seems. Whether it’s a minor seal issue or a more significant plumbing problem, Avalon Pools and Spas in Milton, VT, is here to help guide you through the common causes and solutions for leaks coming from the bottom of your hot tub.
Common Causes of Hot Tub Leaks
- Pump Leaks
The spa pump is one of the most common culprits of a hot tub leak. Issues typically stem from the shaft seal, wet end volute, or pump unions. To address this, inspect the pump closely with a flashlight to identify the exact source of the leak. Replacing worn parts like seals or gaskets can often resolve the issue. - Spa Light Leaks
Over time, the spa light lens or housing may loosen or crack, leading to leaks. Inspect the light area for any signs of water escape. Most light leaks can be fixed by replacing the lens or tightening the locknut. - Filter Leaks
The hot tub filter can develop leaks around the housing or due to worn-out o-rings and gaskets. In some cases, a cracked filter body may require a full replacement. Tightening loose components or replacing damaged parts can quickly resolve these issues. - Plumbing Leaks
Plumbing leaks are less common but can occur due to freeze damage, loose fittings, or deterioration of PVC glue joints. Pay attention to the connections at jets, unions, and fittings for signs of leakage.
How to Diagnose a Hot Tub Leak
Step 1: Visual Inspection
Start by checking around the spa cabinet and equipment bay for visible leaks. Use a flashlight to closely examine all components, including the pump, filter, and plumbing fittings.
Step 2: Turn Off the Pump
If you’re unable to locate the source, turn off the pump and allow the hot tub to drain naturally. Monitor where the water level stabilizes — this can indicate the level of the leak.
Step 3: Remove Cabinet Panels
Carefully remove the exterior panels to access the plumbing. If insulation foam is present, dig into the wettest area to locate the source of the leak. Be gentle to avoid damaging the surrounding pipes or components.
Step 4: Pressurized Test
Run the pump to identify leaks under pressure. Some leaks only appear when the system is running, so observing the hot tub in action is essential.
Fixing the Leak
- Minor Leaks
Small leaks, such as seeping water around fittings, can often be addressed with a hot tub leak sealant like Leisure Time’s Leak Seal. This product is ideal for sealing minor voids and cracks. - Component Replacement
If a specific part like a gasket, o-ring, or filter housing is the issue, replacing the damaged component is a straightforward solution. - Plumbing Repairs
For leaks in PVC pipes, cut out the damaged section and replace it with new piping and fittings. Use high-quality PVC glue to ensure a secure bond. - Insulation Restoration
After fixing the leak, replace any insulation that was removed to maintain the energy efficiency of your hot tub. Spray foam insulation works well for this purpose.
Preventative Tips to Avoid Future Leaks
- Regularly inspect seals, gaskets, and fittings for signs of wear.
- Maintain proper water chemistry to prevent corrosion and damage to components.
- Winterize your hot tub if you live in a cold climate to prevent freeze damage.
- Schedule routine maintenance with Avalon Pools and Spas to keep your hot tub in top condition.
