UV Transformer Upgraded Solid State (4-Pin for Post-2011 UV Units)

FREE Shipping! UV electric 4-pin solid state transformer for all post-2011 UV units. What is the difference between the pre-2011 2-pin UV transformer and this new post-2011 4-pin UV transformer? Just a slight upgrade in quality and improvement of the new solid state transformer. The new transformer has 4 pins, so the UV lamp now has 4 pins instead of 2 to make the connection. All UV units made in 2011 and after will come standard with the 4-pin UV lamp and transformer. If you have a pre-2011 UV unit, you may upgrade to the 4-pin assembly easily by clicking here. Compatible ONLY with EWS sink filtration and RO systems with UV.

Free Shipping Every Day

We always ship free to all 48 contiguous United States. No minimum order requirements. No coupon codes. Just free shipping every day.

Processing Time

Most orders leave the factory facility within 3-5 business days. Larger whole home appliances (like the Spectrum, salt softeners, 1465, etc.) and specialty products (like iron removal, pH systems, etc.) can take up to 10 business days to process. Each product is machined by hand and individually checked for quality, so we cannot guarantee a faster turnaround time (though it does happen).

Shipping Time – Contiguous 48 States

All filter replacements and smaller appliances like drinking water systems, reverse osmosis systems, Heater Guards, and single stage filtration systems ship standard via common carrier (FedEx, USPS, or UPS). These carriers typically deliver within 3-7 business days, depending on your location.

All media replacements and larger tank appliances like the EWS Spectrum, CWL Spectrum, 1465, 1865, salt softeners, pH systems, etc. ship via freight truck. Freight trucking typically delivers within 3-10 business days depending on your location.

Shipping Info – Alaska & Hawaii

Alaska and Hawaii are charged shipping. We don't have any handling fees. Shipping is simply a pass-through cost directly from FedEx or UPS. Please also note that shipping rates are weight-based. The weight of any item can be found on its product page. All weights are rounded up to the next full pound to comply with UPS shipping policy. Please see above for rough estimates on processing and shipping times.

International Orders

International orders incur shipping charges. Before placing any international orders, please contact us so we can ensure that you will be receiving the proper outlets and fittings to suit your home or facility. You may prefer to ship to a USA-based freight forwarder, since we will ship free to your USA freight forwarder (contiguous 48 states only). The freight forwarder would then bill you for shipment to your international address. Please refer to them for their shipping timeframes. If we ship directly to your international address, please be aware that shipping times can increase because of customs or shipping provider delays, which are both outside our control.
