An isolation valve kit is a set of valves that allows you to isolate the water heater from the rest of your plumbing system. This is important for a number of reasons.

Here are a few specific reasons why an isolation valve kit is necessary for a tankless water heater:
- To prevent cross-contamination. If there is a problem with the water heater, such as a leak or a burst pipe, the isolation valves can help to prevent the contaminated water from spreading to the rest of your plumbing system.
- To allow for repairs and maintenance. If you need to make repairs or maintenance to the water heater, the isolation valves allow you to shut off the water to the water heater without having to turn off the water to the rest of your home. This can save you time and water.
