Clevis
Definition and meaning of Clevis in real estate.
A clevis is a U-shaped metal bracket with holes at the ends through which a pin or bolt is passed, used as a fastening link in mechanical assemblies. In residential plumbing, the clevis strap connects the sink lift rod to the pivot rod that operates the pop-up drain stopper.
In more detail
Understanding the clevis and its function is useful for minor home repairs and maintenance. The lift rod on the faucet goes down behind the basin and attaches to a flat metal strap with holes, known as the clevis strap. A metal spring clip secures the pivot rod in one of the holes of the clevis strap, allowing the pop-up plug to open and close.
Adjusting the connection point on the clevis strap is how homeowners fix a sink stopper that does not seal properly or lift high enough. Knowing how this mechanism works helps buyers and sellers resolve simple plumbing issues identified during a home inspection.
