Where can I find a 1 1/4 inch, 3 way mix valve made by Heat Wave?

How can you find where there is a hole when using radiant heating?

Thanks

Do a Google search for your valve. If that brand is not available then just use another brand and hook up according to the directions.

To find a leak use a pressure test. If there is a leak according to the drop in pressure during the test it is probably a hidden leak. Then you will have to use a ultrasonic type leak detector or as happens every so often uncover the pipe until you find it. That is the one problem especially if it is buried under concrete.
