Item has been arrived in Vancouver. I swear could not find it anywhere but finally found TPS had it. Great online store and great work ethics!
10/10. Decent company
I had to buy a new heater for my above ground pool because my old one was not able to do the job anymore. Hopefully 125k BTU should be enough but anyway it's better than nothing. My technician said it's what I need. Placed order online and received the next week. Excellent service guys!!!
Received it, everything was smooth and arrived in great condition. I expected to come it the same week probably not your fault, but UPS. Anyway, great job!
Like it so far! Pentair gives 2 years warranty so I didn't hesitate getting this 125k Pentair above ground one just because I feel it's worth even I ended up paying a bit more. At the end it's good I don't need to worry about it that much 2 years is more than enough for me. Seems like Pentair is more than confident in the product they sell based on the warranty they offer. Completely satisfied!
