Pressure testing your PEX loops before pouring concrete or closing up a wall is the single best way to catch a leak while it's still easy to fix. This kit lets you test up to 4 PEX loops at once by linking their ends together — instead of testing loops one at a time, you test your whole zone in one pass.

Need to test more than 4 loops? Add the 1-loop or 5-loop add-on kits to match your project size.
