ES5 Whole House Water Filters Reviews

Great Product, Awesome Service

“Very happy with the quality of the product and the service. We have gone from having dirty, hard water (awful town supply!) to clean water that feels soft after the installation of a whole-house filter. The wholeprocess was quick, taking less than a week from my first approach to Great Water to the filter being installed. The plumber assigned was friendly and professional. A very small amount of seepage we had after installation was fixed within a day after one text message to Great Water. While the price may put some off, we see it as a saving on the jug filters we no longer need to buy, and on the damage the old hard water used to do to the bathroom, kitchen and cars. I would definitely recommend Great Water's household filter system. ”

Great Water Filter system

We are really pleased with the system we had installed to reduce the amount of scale build up in our drains and shower heads. It gives me peace of mind that my expensive appliances are also protected. I looked for months for a company that could provide a comprehensive system we were needing to filter the water coming into the house. We notice a big difference. It is wonderful that we get reminders when our filters are due for replacement. Thank you so much Great Water!
Regards, Morreen

Excellent

Excellent, efficient and punctual. Drama free installation of an effective water filtering system... this is my third house with the same system. Very pleased - thank you!

Pam20 Sep 2024

Fantastic experience

“Fantastic experience from start to finish. No pushy sales like the other company we enquired with. We kind of knew what we wanted, and any questions we had were answered honestly and concisely. We’re loving having filtered water throughout the whole house with no noticeable water pressure loss. Thanks for being such a wonderful company to deal with. I have already recommended the whole home filtration system to several of our family and friends”

Fantastic whole house water system

A great company to deal with - from the people at the homeshow that we met, to the office with follow-up and our plumber who installed the system. All our questions were answered, we were kept up to date with what was happening and we'll now get reminders when our filters are due to be changed. Couldn't be happier with the quality of the service and our water! Thanks guys!
