    Exact replacement for my AO Smith UV unit

    Looking for replacement UV lamp and quartz sleeve for my AO Smith UV water filter, I found mostly cheap fake parts on the market. I don't want to cut corners on my water purity. Glad I found these Viqua parts, which are exact OEM replacements. Great service from The Water Store. These super-fragile parts were carefully packaged.
