Hot Tub Repair Method 3
As the alternatives of the method 1, here we provide some other ways in repairing your hot tub. The methods are not really different with just some additional methods that you can try.
After you are in equipment compartment, the first thing you have to check is the pump, often the pump seal is the main reason for the leak. If you find water leaking from the pump, you can decide to replace the seal or replace the entire wet end to fix the leak.
If you want to save your time from further leaks, replacing the entire wet is the option for you, because replacing the seal is quite hard without breaking other components within the wet end. In short, you can replace the seal or the entire wet end, but we recommend you to replace the entire wet.
If you find the pump is okay, check the union fitting around the pump and the heater. It can be the source of the leaks even for a brand new hot tub due to the vibration during shipment.
To fix it, DO NOT use a wrench to tighten it up! It can be tightened by hand, or you can remove the realign parts to make it straighter fit then tighten by hand. Once again, DO NOT use a wrench because it can damage your hot tub. Fix the leak in the union and you just finish your hot tub repair work.

And then, some manufacturers build a hot tub with the valves installed on both side of the pump, so water doesn’t need to shut off. So you can access the pump and replace it. Our recommendation is; remove the valves because they are the common leak source of a hot tub. So you can save a lot of time and headache.
Connections and Jets
The next step if you didn’t find the source leak is, inspecting all of your pipes, jets, and connections. The leaking jets because of the bad gasket un the jet, but it probably happen because of the bad over time and you should replace it. Check the pipe if it needs to be tightened, tight it up or seal it with PVC glue.
