Review on Replacement UV Lamp For Viqua S810RL Water System (S8Q-PA) by Ashley Belehar

Works at expected and described from manufacturer. Easy to i install. Do not order a knock-off because it will void your warranty. just an FYI, Walmart will show that the sleeve and O-ring are recommended to be ordered together. I did that, but it turns out I did not need those items. The O-ring came with the replacement lamp AND the Sleeve. So I ended up with 3 O-rings. I plan to keep them, hopefully I will be able to use them at some point. Just save your money.
