Hi I’m Vance and welcome back to Repair and Replace.
In this episode, I'll show you how to install an American Standard Selectronic Flushometer.
To begin, you'll need a flushometer, a smooth jaw wrench, and a flat blade screwdriver.
You might also need a pipe cutter, solder flux paste, lead free solder, and a blow torch
First, dry fit the flushometer in place to check the height and position.
Starting from the top of the fixture, measure up to the middle of the supply line.
Water closets and urinals will have a max height of 11-1/2".
The flush pipe can be trimmed down to a different height if needed.
If you measure from the center of the supply line, to the centre of the valve,
it should be 4-1/4" to 5-1/4".
Next measure from the wall to the center line, it should be a minimum of 1-1/2" away.
Now check the length of the copper tube.
Measure from the wall to the centerline of the flushometer.
The copper tube should be one inch shorter than that distance.
Cut the pipe if necessary.
Next solder the adapter to the copper tube to secure it in place.
Cut the cover tube 1-1/2" shorter than the centerline measurement.
Slide the wall flange and cover tube over the supply pipe.
Now screw the inlet stop onto the adapter.
Use a smooth jaw wrench to tighten it into place.
Next install the spud or flush pipe.
Slide on the vacuum breaker coupling.
Next slide on the spud coupling assembly which is made up of the coupling nut, flange,
friction ring, and rubber washer.
Align the flush pipe and hand tighten the nut.
Now assemble the vacuum breaker.
Slide the plastic insert into the lip on rubber sleeve.
Now insert the vacuum breaker into the flush pipe.
Set the flushometer body on the flush pipe and hand tighten the tailpiece coupling
and hex coupling.
Now use a smooth jaw wrench to secure each connection.
First remove the plastic tab to activate the sensor.
Now place your hand infront of the sensor for 10 seconds, then pull it away.
You should hear the solenoid click, and this will let you know that the sensor is working.
In most installations, the default sensing distance of 16 inches should be adequate,
but the distance can be adjusted up to 32 inches if needed.
Watch the video linked below to see how to calibrate the sensor.
Turn on the shut off valve to the supply line.
Next use a flat blade screwdriver to open the control stop one full turn.
Now test the flushometer.
The first flush should eliminate all the air from the lines.
If this is a new installation, it's recommended to flush the valve 4 or 5 times
to clean out the supply line of any debris.
Now adjust the control stop until you get a normal flush with a quiet operation.
Finally, replace the cap.
