## Customer Reviews

### ⭐⭐⭐⭐⭐ perfect replacement for the OEM part
*by P***7 on February 12, 2016*

It's been working perfectly for 6 months now. Set at 2 PSI for circulating pump flow sensor use on a nearly 20 year old JEM Spa hot tub. Used a small bit of plumbers putty to ensure a tight seal. Teflon plumbing tape might work as well. Biggest challenge was clearing the broken off stem of the original unit out of the pressure sensor insertion hole on the heating unit. Carefully used a drill (can't remember bit size) to remove the majority of the old stem and then some steel picks to clear the leftover plastic from the threads. Once this was done the new unit easily screwed in and work perfectly. Took a cellphone photo of the wiring of the original unit before removing to ensure they were replaced exactly the same on the new unit.

### ⭐⭐⭐⭐⭐ Worked great after doing what everyone said not to do
*by A***R on November 13, 2019*

They say do not adjust the pressure switch but after I installed kept showing flo fault. When I pushed hydro button everything worked until it stopped circulating. Then it would show flo fault again. I turned 2 times 1 direction nothing happened. So I turned it back 2 times and then started to turn 2 more times that way and I heard a click. I turned off hot tub and restarted and been running great ever since.

### ⭐⭐⭐⭐⭐ Over Pressure Error Fixed!
*by K***G on December 14, 2018*

Fixed my over pressure error in about 3 minutes!
