Hot tubs and spas are not supposed to leak. However, over time, this can happen in older models. Knowing the areas to look for leaks is the first step in preventing them.
Hot tubs and spas can also leak in various locations. Most of the time, they are not found on the surface itself but usually find them through plumbing joints and gaskets.
The water in a spa can evaporate several inches if it is left open or is used for a long time. If it is used excessively, this may cause a leak.
If you think you are losing water in your spa - open the equipment access and check these areas first:
- Water dripping off of the pump (unions, drain plugs, shaft seal)
- Water dripping off of heater (unions, pressure switch)
- Water pouring out of blower (check valve failure)
- Water leaking from valves (valve body or gasket failure)
- Water leaking from spa light (gasket failure)
- Water leaking from jets (internal cracks or bad gasket)
Still Leaking? If you've got no puddles or dripping water after going through several baths, it's time to check the jets for leaks. These small jets tend to leak where the flexible pipe is attached.
They can also lose the seal that's made by a rubber gasket against the back of the spa. This can happen even though the jet body is designed to lock.
Spa Jet Tools. Many spa jets have a special wrench that's used to tighten the lock nut on the valve or the spa side. Other tools are used to keep the jet from spinning while the valve is tightened.
FULL FOAM INSULATION:
For spa systems with full spray insulation on their undersides, it can be challenging to find the source of a leak. However, with a few simple steps, you can prevent the spa from leaking and find the source.
If you see water coming out of the spa on one of its sides, it's possible to explore this area by removing the cabinet. However, be careful not to damage the other side panels since this will most likely cause them to get damaged.
Once the insulation has been secured, the easiest way to cut it is by opening the holes with a kitchen knife or a drywall saw. Follow these steps to avoid damaging the insulation.
After a pipe or jet has been buried in insulation foam, replace the foam with spray foam insulation. This will help fill in the gaps and prevent further damage.
A QUICKER METHOD TO REPAIR LEAKING SPA JETS
You may have already wondered, "can't I just put a sealant on the inside of the spa, around the jet fitting?" If the leak is the gasket and not the pipe connections, which it usually is.
You can test the effectiveness of spa jets with food coloring by squirting small drops of dye underwater.
You can test the dye around the jets with food coloring. If the dye doesn't get through, turn the pump off and wait for the jets to empty.
You may want to try applying a seal around a suspected spa jet, but this may not fix the problem and could cause a mess.
