Designed to mount directly to the slide valve arm on Valterra and Bristol 3\" (and compatible 1.5\") waste valves, the unit uses corrosion-resistant metals and plastics and provides a visible indicator light showing open or closed position. Installation is straightforward for users comfortable with basic hand tools and 12V wiring, and the unit cycles quickly to fully open or close the valve.\u003c\/p\u003e\n\n\u003ch3\u003eHow quickly does the Auto Drain open and close?\u003c\/h3\u003e\n\n\u003cp\u003eThe 3\" model completes a full open or close cycle in under 4 seconds, giving you fast, reliable operation when dumping tanks.

It suits owners of motorhomes, travel trailers, and fifth wheels using Valterra or Bristol style slide valves who prefer a low-current 12V solution with corrosion-resistant parts and a clear open\/closed indicator. If you need a heavy-duty retrofit that reduces manual handling of the waste valve and speeds the dumping process, this kit provides a straightforward upgrade.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does the Auto Drain require plumbing changes?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No plumbing modifications are needed; it mounts to the slide valve arm on compatible 3\" or 1.5\" waste valves.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What electrical power does it use?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: It runs on 12V DC and draws about 200 mA, compatible with standard RV electrical systems.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"BARKER","offers":[{"title":"Default Title","offer_id":48081466654878,"sku":"B003VAYMB4","price":211.92,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/barker-auto-drain-front-mounted.jpg?v=1785805945","url":"https:\/\/northtrailauto.ca\/products\/barker-3-auto-drain-rv-slide-valve-actuator-kit-12v-automatic-retrofit-with-indicator-light","provider":"North Trail Auto","version":"1.0","type":"link"}
