 Make sure that the water supply 
(or the pump) is on. 

2.

 

The

Check the position of 
the pilot’s adjusting 
bolt (

4A

)  

4.

 

 Turn the adjusting bolt (

4A

counter-clockwise, one turn at a 
time, allowing sometime between 
turns for the valve to respond. 
Continue until the required 
pressure is reached. 

Valve does not close

Debris on the sealing 
seat 

1.

 

The valve is constantly 
discharging small 
amount of water 

1.

 

  Turn the 

3

-way selector (

3

) to 

"open" for 

5

 seconds, and then to 

"close". 
If the problem continues, turn off 
the water supply to the valve.  
Remove the bonnet and 
diaphragm, remove the foreign 
object, and check that the 
diaphragm, body and cover are not 
damaged. 

2.

 

The diaphragm is 
damaged 

2.

2.

 

 Turn off the water supply to the 
valve.  Remove the bonnet and 
replace the diaphragm. 

3.

 

The 

3

-Way selector is 

in the "open" 
position. 

3.

 

Check the

). 

4.

 

Disconnect the 
control tube from the 
self-flushing filter (

2

and check for free 
water flow. 

4.

 

 Turn off the water supply to the 
valve, remove the finger-filter and 
clean or replace it.
