    Great Service, honest answers!

    I had a worry free order from them and then followed up by emailing them a question. Their response was to reassure me *not* to buy an unnecessary add-on. I truly appreciate the honesty! Thank you Heidi! Great service, and they didn't try to sell me something useless. Wayhay!

    Quality and value

    This was a difficult RO replacement filter to find, but Water Store had it. It was as described and fit properly in place of the original. We take some comfort in knowing it did not ship from China as our experience with such products has not been good. The new check valve that came with it did not function well, however, and made terrible noises until we put the old one back. The new RO filter is performing quite well! Thank you Water Store!
