    5.0 out of 5 stars Happy I found these here on 鶹!
    Reviewed in Canada on June 20, 2025
    Verified Purchase
    For whatever reason, I have to replace this part in my heater every year or every other year. It’s not expensive and it’s easy to change so I don’t mind. What is helpful is that I remove it at Poole closing time each year and store it indoors or in the garage. That seems to help and make it last for an additional year.
    I usually order a couple at a time just in case
    I love the fact that they’re inexpensive here on 鶹. I purchased it from a pool supply store and paid two or three times the cost in the past.
    Delivered about a week after I ordered.

    Easy to install just look up how to do it on YouTube and compared to the OEM Pentair, it's a no-brainer! This is a fraction of the cost and works well. Highly recommend.
