What is a Tankless Isolation Valve Kit?

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

Preventing cross-contamination. If your tankless water heater develops a leak, the isolation valves will prevent the contaminated water from entering your other plumbing fixtures.
Allowing for repairs. If you need to repair your tankless water heater, you can do so without having to shut off the water to the rest of your home.
Easing maintenance. The isolation valves make it easier to flush and clean your tankless water heater.

Why Do You Need a Tankless Isolation Valve Kit?

If you have a tankless water heater, you need an isolation valve kit. Even if you think your tankless water heater is in good condition, it’s always a good idea to have an isolation valve kit on hand in case of an emergency.

Different Types of Tankless Isolation Valve Kits

There are two main types of tankless isolation valve kits:

Manual isolation valve kits. These kits consist of two valves: a shut-off valve and a drain valve. The shut-off valve stops the flow of water to the tankless water heater, and the drain valve allows you to drain the water from the tankless water heater.
Automatic isolation valve kits. These kits include a pressure sensor that automatically closes the shut-off valve if the water pressure drops below a certain level. This can help to prevent cross-contamination in the event of a leak.

Choosing the Right Tankless Isolation Valve Kit

When choosing a tankless isolation valve kit, there are a few factors you should consider:

The size of your tankless water heater. The isolation valve kit you choose needs to be compatible with the size of your tankless water heater.
The type of valves you want. Manual isolation valve kits are more affordable, but automatic isolation valve kits offer more protection against cross-contamination.
The price. Tankless isolation valve kits can range in price from a few dollars to several hundred dollars. Choose a kit that fits your budget.

A tankless isolation valve kit is an essential safety device for any home with a tankless water heater. By following the tips in this article, you can choose the right tankless isolation valve kit for your needs.
