So easy, pleasant and Canadian eh

It is so refreshing to be able to order right out of Canada. My order arrived in a day! I was searching YouTube for a solution to my water softener drain leaking (after a higher water bill) and discovered Gary’s videos. Thank you Gary the Water Guy and your friendly team for what is probably the easiest home repair I’ve ever done. I can’t be more pleased.

Thank you for your kind words! We are glad to hear that you had such a positive experience with our Canadian-based company. Our team strives to provide easy and efficient solutions for our customers, and we are happy to have been able to assist you with your water softener repair.
Thank you for choosing Water eStore and for supporting local businesses. We appreciate your feedback and look forward to serving you again in the future.
Cheers! - The Water eStore Team

CW (Sydney, AU)
Clack rebuild kit

With the excellent tutorial videos, this kit was exactly what was needed to stop my iron filter continuously trickling to drain. I think if you are replacing the spacer stack assembly, the wrench is a must, however it will also be very useful now for regular maintenance of the valve and works on all the caps, not just the spacer stack, by using the other end of the wrench.

Thank you, CW, for your business, kind words, and for taking the time to write this review – much appreciated!
We look forward to helping you again soon.
Take care and stay safe.
