This was a game changer for me

This was a game changer for me. Over the past 25 years I have become quite the plumber. Customer Service is top notch and their advise and encouragement has gotten me through several plumbing disasters. I live on a remote island in Alaska and your team has certainly made a GRAND difference in my ability to keep my 30 year old Hot Tub up and running.

When the original one cracked, I chose this as a replacement part. It worked great and sealed well. I just screwed the nut on to the existing piping.

Called in thinking I needed to replace entire heater tube due to broken collars. Advised that I could just buy split ring collars at a fraction of the cost.
