Customer Reviews (16)
We were very happy it didn't take long to get water heater customer was happy everything work very well thank you so much
I am very happy with the purchase of this product and highly recommend it. My old water heater was a huge tank taking up space and was leaking. This one works great and does not take up much space. It was fairly simple to install and I am happy to take a hot shower with endless hot water. No more cold showers for me.
Easy installation, great performance
Heater arrived quickly, Customer service was helpful and it works great. I would definitely recommend factory pure
Give it another month and contact me so far so good is all I can do for now
