Optimal Performance with Compatible Reverse Osmosis Membrane for Rainsoft Systems Review

, they mentioned that it replaces part #18644 and 18571 but it is different from what they described on the website and pictures.

Pre-ordered and re-ordered. Customer service is excellent. Item received earlier than expected. Comparable to RS product but much cheaper prices!

I think it will fit, it didn't quite fit. Rainsoft deceives its customers and demands 150 dollars. This and their archaic process of handing the phone over to the dealer will make me order this next time.

This was a replacement for the original diaphragm. The only problem after replacing them at the same time as the filters was that the amount of air in the system took some time to empty. During the first month I had to use bypass mode several times to get the air out.

Nice and well built. The material seemed to match my Rainsoft ro. However, the filter did not fit. It didn't fit because of the yellow spring on the bottom of the original Rainsoft membrane. This missing part prevented the block from fitting tightly, causing water to flow around the filter.
