Do not connect plastic piping or tubing directly to the ultraviolet sterilizer system because the UV light will break down plastic in a short period. The best way to connect is with an ultraviolet sterilizer dielectric union that connects stainless steel to copper that will not corrode.
The union has a rubber bushing that keeps the dissimilar metals from contacting each other which would cause corrosion and leaks over time.
Ultraviolet Sterilizer Dielectric Union for UV Light, 3/4″ or 1″
Dielectric Unions are available at plumbing supply stores but may be hard to find. We have them available at a very fair price, and if you order them from us you save time and do the job right.
If you have questions about how to properly install a UV system please call our staff of WQA Certified Water Specialists for assistance.
