Low-Flow Toilets
By: , This Old House magazine (Page 2 of 3)What You'll Learn:
Anatomy of a Low-Flow Toilet
FLUSH LEVER: Pulls the lift chain.
LIFT CHAIN: Opens the flapper. A chain float limits the flush to 1.6 gallons by closing the flapper when the tank has drained to a set level.
OVERFLOW TUBE: Protects against an accidental overfilling of the tank.
FLOAT: Shuts a valve on the supply line when the tank level reaches a predetermined depth.
FLAPPER: Releases tank water into the bowl. When released by the chain float, drops against the flush valve seat, sealing the tank so it can refill.
TRAP: Holds water in the bowl, blocking the entry of sewer gases, until the flow from the tank pushes the water over the weir.
SIPHON JET: Concentrates flow from the tank, jump-starting the siphoning effect.
RIM HOLES (not shown): Release water during the flush, cleaning the sides of the bowl.
