A bypass kit is often something that is overlooked but is very useful for many koi hobbyists. Make a bypass between the inlet, outlet and include a third ball valve, you then have full control of the flow that goes through the UV.
This can be especially beneficial when you have fish parasite. If an outbreak does occur in the pond, you will need a very low flow through the UV. If a bacterial outbreak such as a white spot occurs in your pond, then with the bypass you can effectively control and manage the outbreak swiftly.
The bypass allows you to control contact time and increase this further by opening the ball valve, resulting in the outbreak disappearing quickly.
If you create a separate dedicated circuit for your UV, maintenance will become simple and hassle-free. Creating a bypass enables you to keep your filtration online and uninterrupted.
If you use a ball valve for both the inlet and outlet of the UV you can then easily remove the entire unit. This means that you can easily perform your yearly bulb replacement and your bi-annual quartz tube clean.
