There are multiple areas where a leak can occur on a hot tub. For that reason, you may think it is extremely difficult to locate a leak. Luckily, as long as you know where to look, it's quite easy to find the source of the water loss. Here are five of the most common culprits of your hot tub leak:
Culprit #1: The Pump
The most common component of your hot tub that will spring a leak will most likely be the pump. Before you can check for a leak safely, you need to switch off the power to the pump. Once this has been done, you can feel and look underneath it. You may need a flashlight for this. If you feel or see water, this is a tell-tale sign that there is a huge problem. Usually, the pump seal can just be replaced. However, in some cases, the entire pump will need to be replaced. Sometimes, replacement is simply the easiest option.
Culprit #2: Union Fittings
Another common cause for a hot tub leak is the union fittings, which can be found at the tub's pump as well as the heater. One possible reason for these leaks is from the union fittings becoming loose over time due to vibration. Check them all to see if any are loose and are your possible culprit of the leak. If so, it is very important that you only tighten these fittings by hand rather than with a wrench so as to not get them too tight.
Culprit #3: The Heater
The next area that you should check for any leaks is the heater and its surrounding components, including the pressure switch. If you notice that any of these components have water leaking from them and are defective, they should be replaced immediately.
Culprit #4: Valves
Perform a close inspection of each valve on your tub. You will need to determine the type of valve that you have so that you can purchase the right type of valve for repair or replacement. For example, knife-style valves consist of two pieces that bolt together with a gasket in the middle that is prone to failing. It is that gasket in the middle that typically results in a leak.
Culprit #5: Connections
There are many connections on your hot tub. You should go around your hot tub and check all the jets, pipes and the rest of your connections for any visible sign of a leak. In a lot of cases, you will simply need to tighten the connection back or re-seal it. If you find a leaking jet, though, you will probably need to replace a defective gasket.
