Ballcocks  (also known as Fill valves)

pro45 new

Professional Grade Fluidmaster 400A Ballcock
The nice thing about these ballcocks is the brass shank extending down through the tank.  On hightanks, this eliminates the unsightly plastic shank extending below the tank.  Valve supplied with plastic nuts. Metal nuts in Chrome, brass and nickel sold separately below.  These are the best on the market!

Rear-Inlet (Curtin Rotary) Ballcock
This Ballcock is used in toilets where the water feeds into the tank right through the back of the tank.  Popular during the mid to late 1920’s through the mid 1930’s.  Inlet of ballcock is 3/8” pipe.  There were several varieties of these, this one is the only currently being reproduced.  Rebuild parts are available, see bottom of this webpage

Side fill Ballcock
Here we have the correct fill valve for the early wooden hightanks.  This valve actually has the mounts cast into the valve body, so it’s just a matter of attaching the valve to the top of the tank.  Supplied with a brass float rod and copper float, this valve’s inlet is 1/2” IPS thread.  No need for having to rig a mount like you would with the below version.
