The media could not be loaded. Re-doing my product review , after a failed attempt to make this item work , I made a " bad " review on this item , after posting it here , I got an email from Kimberly from Customer Service to let me know she could send me a new filter set up If I would give them an other chance , I said yes , next day or two I had a new box with a new filter set up , I got really impress by the way they wanted to make things right about their product , so After few days , I finally got to do another set up with the filter on the new tankless water heater in my house , set up was easy this time after Kimberly gave me some pointers of what I should do this time in order to not have a leak , I fallow her instructions and I am happy to say that the system works as advertised ! No leaks and I am really happy that the new set up works perfectly ! Thanks to Kimberly for her time and effort to make things right on their product . Recommend it 100% !

Perfect fit each time, and ease of removal and installation of the filter! Good quality and price!

I’ve had this installed for about a year now I haven’t really noticed too much difference and the hardness of the water, but that sort of a hard thing to gauge and and so far it hasn’t leaked.

This is my second Waterdrop product. I also have an under sink filtration system. This scale inhibitor is a must when installing a tankless water heater to prolong the life of your water heater. Others have reported leaks at the threads, but if you use a good amount good teflon tape & tighten appropriately, you should be fine. Other than that, nothing else I can report on until about a year when its time to flush out my tankless heating system. Eddie K out !!

Wow amazing works and water feels great not hard like before

Tee leaks. On my third attempt. Two different fittings and now a brass nipple. Came to the conclusion the included tee is not good.

You’ll never know if it works. It would take a couple years and disassembly of your water heater to find scale. Other than that, the assembly was easy.

Got it as a replacement. Have purchased from this merchant before.
