Our commercial dog water fountain for dog parks is manufactured with a Type 304 stainless steel 10 inch Schedule-10 main column and 7 gauge flange. The fountain has a high-polished 18 gauge stainless steel bowl with anti-rotational, anti-squirt, solid stainless steel bubbler. The bubbler is activated by a steel foot-operated push button assembly which controls a lead-free, self-closing valve.
