Customer Questions and Answers for Standpipe Nut (Threaded Retaining Nut) by Whirlpool

This standpipe nut secures the washer drain standpipe or tub outlet fitting to the drain assembly, preventing leaks and keeping the drain connection stable. Simple replacement restores a proper sealed drain connection. What it does:

• Threads onto the standpipe or drain outlet to hold the drain tube or fitting in place
• Creates a tight connection to help prevent water leaks at the drain junction
• Restores proper alignment and stability of the drain hose or standpipe assembly
• Common fix for leaking or loose drain connections around the washer drain area

• Disconnect power and water supply before working on the drain or pump area
• Inspect mating threads and any gaskets; replace damaged seals as needed for a proper seal
• Thread the nut by hand to avoid cross-threading, then snug with appropriate tool—do not overtighten
• Test for leaks after reassembly by running a short drain cycle
