Leaks in hot tubs are not easy to fix especially if you have difficulty locating where it is coming from. Nevertheless, there’s no need for you to call in a professional since it’s very possible for you to get the job done on your own. The things you will need for this project are a pump wet end seal, plumbing tubing, heater assembly manifold, knife and gate valves, jet bodies, wrenches, acrylic spa shell. Prepare all these materials first before starting to work. In the meantime, here’s the step by step guide in fixing a hot tub leak:


Step 1. Check the pump first since it’s one of the most common places that leaks occur. Make sure you turn the power off first before checking the pump. If you can confirm that the problem is coming from the pump, you will need to replace the seal or the pump itself.

Step 2. Check the heater next. Look for problems that may be present in the heater itself, the pressure switch, and the other components. Any parts that may need some fixing should be fixed or replaced immediately.

Step 3. If there is no problem with the pump or the heater, check the union fittings that are located around them. Usually, a hot tub may leak if the fittings become loose. Check the fittings and tighten them by hand if necessary.

Step 4. Another part you might want to check for problems would be the valves. The gasket present in the valve may get damaged and cause leakage. If the problem is with the gasket, you will have to replace as soon as possible.

Step 5. Next, check all the connections, as well as the jets and the pipes. For damaged PVC pipes, the solution is to patch the cracks or holes. On the other hand, loose connections can be sealed or tightened. If the problem is a leaking jet, there’s a huge chance that the gasket needs some replacing.

Step 6. Check the shell as well because even though most shells are made of strong materials such as fiberglass, they can still acquire some damage that causes leaks.

Step 7. After checking all the components and still you can’t seem to find the cause of the leak, then you might want to check other parts of the tub for problems. Sometimes, the leak may be caused by a hole in the tub itself. To find out the location of the hole or the crack, fill the tub with colored water. Mix some dye into the water and observe the tub for leaks. The dye in the water will make it easier for you to locate the problem especially if the leak may result to puddles underneath the tub. Once you confirm that the problem is indeed a hole in the tub itself, then you will have to allow the tub to dry completely and fix it accordingly.
