What is the primary function of a spa diverter valve?
A spa diverter valve’s main job is to control the flow of water, allowing you to direct it to different parts of the spa, such as various jets or features. This is typically done by turning a handle which rotates an internal component, redirecting the water.
What are the common reasons a spa diverter valve might fail to work properly?
A common issue is a cracked, broken, or stripped diverter valve insert. This insert is what directly rotates to divert the water, so if it’s damaged, the handle will not be able to properly redirect water. Another potential issue is the failure of O-rings, which can become worn or damaged, causing leaks around the valve.
Why is it important to turn off the power to the spa before working on the diverter valve?
Turning off the spa’s power is crucial because the plumbing system is pressurized when the spa is running. If you open the valve while the power is on, water will forcefully spray out, potentially causing injury or making a mess. Turning the power off eliminates the water pressure, making it safer to work on.
What are the key components inside a spa diverter valve that are prone to failure?
The key components prone to failure are the diverter valve insert and the O-rings. The insert itself can crack or break, preventing proper rotation, and the O-rings can degrade, causing leaks. These are the two components that should be inspected when troubleshooting a diverter valve issue.
What indicates a worn-out O-ring in a spa diverter valve?
A worn-out O-ring is usually indicated by water leaking from the valve’s housing. This is because the O-ring is designed to create a watertight seal, so when it is not properly sealing water will leak out. The O-ring may also appear flattened or degraded.
What are some of the common types of debris found inside a spa diverter valve?
Common types of debris found inside a spa diverter valve include broken-down pieces of plastic or rubber, often originating from the O-rings themselves. There can also be calcium build-up or general grime and gunk from the water. This debris can contribute to leaks or hinder the function of the valve.
How do you properly re-install a spa diverter valve insert?
When re-installing the insert you should pay attention to the ridges on the insert and the valve housing. It should be lined up correctly so that it seats fully, and you can test this by pushing it in and turning back and forth. It’s essential to note the orientation to make sure it is aligned with the flow of the water.
How should you correctly position the handle when reinstalling it on the diverter valve?
When putting the handle back on, you want the handle’s range of motion to be the same on both sides (left and right). You want to make sure the handle doesn’t stop too far in either direction because it’s hitting the spa shell. Center the handle as much as possible when putting the cap on to ensure an equal range of motion.
