Our brass 15mm Male x Female Backflow Prevention Mini Dual Check Valves are of the highest quality, are warranted to a working pressure of up to 1,200 KPA and are Watermark approved.
Note: These are supplied at no additional cost with any purchase of a manual under-toilet seat bidet attachment but they can be purchased separately (GST and Postage included) if you purchased a manual under-toilet seat bidet attachment from a retailer that did not supply one. This is typically the case from overseas retailers. These Backflow Prevention Valves are required to be used in Australia when attaching a manual under-toilet seat bidet attachment to your plumbing.
