Troubleshooting Sprayheads (Standard with Neoprene Spray Ring Grommet)

Problem Cause Solution

Water splashes

over the rim of the

bowl.

Foreign matter has reduced

the size of the sprayhead

slots, causing greater

pressure at the open slots.

Clean the sprayhead:

1. Disassemble the sprayhead and dislodge any dirt, lime build-up and foreign debris with a

wire brush.

2. Sprayheads with rubber grommet spray rings may be cleaned by rubbing a coin over the

grommet.

3. Throttledownthevolumecontrol(watersprayshouldstrikethebowlwithoutsplashing

outsideofthebowl).

Water ﬂow

diminishes from

the sprayhead.

Strainer portion of the

stop-strainer-check valve is

plugged.

Remove and clean the strainer screen from the stop-strainer-check valve.

The sprayhead shown above includes a perforated neoprene spray ring grommet that

is self-cleaning. The water pressure ﬂexes the spray holes which slows accumulation

of foreign matter and tends to “break loose” any such deposits that may have

accumulated.

Repair kit does not include sprayhead grommet. Order as a separate item.

Sprayheads Parts List

Troubleshooting TouchTime

Problem Cause Solution

The

TouchTime

push button

unit does

not function

properly.

Power out Make sure the water supply and the 24 VAC power are both turned on.

Loose wiring

connection

1. Turn the electrical power off.

2. Check the wiring for loose connections or corrosion and correct if necessary.

3. Turn the electrical power back on and retest the push button.

Defective

Transformer

1. Turnthewatersupplyoff(theelectricalpowershouldremainon).

2. Set the volt meter scale to be able to read “24 VAC”. Connect the volt meter leads from the transformer.

3. The voltage reading should indicate 24 VAC ± 10%. If you are unable to obtain a proper voltage reading, the

transformer is not working properly and needs to be replaced. Contact your Bradley representative to order a

replacement transformer.

Defective

Solenoid

Valve

1. DisconnecttheGreen/Graywiresfromthesolenoidandthebrowntransformerleadsfromtheterminalblock.

2. Connect the brown transformer leads directly to the solenoid. The solenoid coil should activate and you should

hear a single click and a humming noise.

3. If the solenoid still does not function, turn off the electrical power. Then remove the four screws that secure the

clamping plate to the valve body. Be careful not to lose the armature or spring.

4. Removethediaphragmandcleanitgentlybutthoroughly.Holdthediaphragmuptoalightandndthesmall

hole which is located about halfway between the inner diameter and the outer diameter. Make sure the hole in the

diaphragm is not plugged.

5. Reassemble the valve in reverse order and test again with power from the transformer.

If the solenoid coil does not activate, the solenoid valve is not working properly and needs to be replaced. Contact

your Bradley representative to order a replacement solenoid valve assembly.

Defective

Switch

The TouchTime

switch assembly is not working properly and needs to be replaced. Contact your Bradley

representative to order a replacement switch assembly.

Make sure there is electrical power going to the

transformer and there are 24 volts coming from the

transformer.

Be sure to turn off electrical and water

supplies as instructed during troubleshooting.
