  • Affordable & works great
This part saved the heat element in our hot tub. It was very easy to change & has been working now for 3 months, highly recommend.

  • Saved Me Several Hundred Dollars
My pool heater (used only for the jacuzzi) stopped working and there was an error code, which I googled and found out that I needed a new stack flue sensor. I'm not handy but I was easily able to install this sensor in my pool heater. I just needed a flat head screwdriver to open the front panel. I looked at a couple YouTube videos to see exactly what I was looking for once the panel was removed. Then it was just a matter of disconnecting the old sensor and connecting the new one. That was it. ... show more

  • Super Easy to Install
We received a quote for repair to our Stack Flue Sensor from a local pool company, because our Jacuzzi wasn't getting hot. They quoted us $180 for this part and $95 for the install/labor. I decided to look up the cost of the part, to see what the markup was, and boy what a HUGE markup. I then saw a 1 minute video that showed how to switch this out--piece of cake. I am a woman, who is handy but wouldn't say this is my lane in terms of repairs, and it took me all of 10-15 mins to replace. Start to finish. The hardest part was removing the old/chewed up part. Recommend. ... show more

Was not happy with this product. I bought 6 of these stack flu sensors so far 3 out of 3 have not worked. I will not buy from this seller again

  • Pool Heater Good as New
Quote from pool boy was $150 to replace, including $100 for parts. Bought this part for 15% of the quoted cost and installed myself in about 15 minutes. Works like it should.

  • Saved us a bundle!
Wow! Ordered on Saturday, arrived on Sunday. Installed before the delivery truck left town. This easy fix saved us a couple of hundred bucks and got us in the pool a week or two earlier. Our pool company “put us on the list” but we were able to cancel the heater repair. We really appreciated the availability of the product and lightning fast delivery. ... show more
