These work great for swimming pool.
I bought these for changing the ph in my pool. Dropped them in the center of my filter. Worked like a charm! No more green or cloudy pool! Highly recommend!

Fit my needs perfectly
The Freeze caused a lot of damage to my plumbing and parts were scarce in this area. Amazon came through for me.

All Supply Giant products are quality!
Purchased a single 1-1/4” coupler and a 1-1/2” coupler for copper pipe, local big box stores in my area do not carry these, this is more of a plumbing supply house purchase, the problem with a vast majority of these is that those stores only like selling to contractor’s and if they do they only sell in bags of 10, I don’t need 9 spare’s sitting around. Pay for TV and get free shipping, perfect!

We purchased these to use in our swimming pool to help with the algae. These have been wonderful, highly recommend, and have been recommending to all of our pool community.

Beautiful copper
The media could not be loaded. What an amazing piece of copper. Honestly I would polish it and keep it instead of using it for work.Súper fast shipping too .
