If you have a question about using  the kit or how to perform a test, by far the quickest answer will always be to log on to the forums at www.Troublefreepool.com and ask your questions to hundreds of users there.

You can also reach us by email at TFTestkits@gmail.com.  

You may contact us by phone @ (919) 529-6056 or (919) 528-1104.  We are a small company and the phone is not always answered by a live person.  If you leave a message, we are good at returning calls promptly and solving the issue quickly.
