Maintenance:

   

A periodic test of the Hydrant should be performed.  The dome handle should be opened and closed to assure that no 
foreign material has entered the cavity within the dome.  Difficulty in turning the handle is a possible indication of the 
presence of foreign matter within.  To remove this matter, first remove the plastic cap at the top of the handle.  Second, 
loosen and remove the ¼” lock-nut and washers inside the cavity below this cap. 
 
After removal of any foreign material, replace the handle and attachment hardware. 
 
The hydrant should periodically be examined to insure that the working and operating parts function as intended.  The 
hose threads on the vacuum breaker should be free of indention that may cause a hose to not attach properly to the 
hydrant.  The vacuum breaker should function as intended allowing for air to enter the stand-pipe once the valve is closed 
while barring fluids from back-flowing into the assembly.  

 
The provided wye-strainer should be installed as shown in Figure 3, and at least annually be cleaned of debris.  
Contamination in the water supply line may cause the valve to fail.  The strainer screen mesh should be removed 
and flushed and then re-installed prior to continued use of the hydrant. 
 
Repairing the Ball Valve:

  

The ball valve and assembly is not intended for “in the field” repairs or replacement by those not trained as to the 
technique of removal and re-assembly of the valve and piping assembly.  If it does become necessary to make repairs to 
this hydrant, contact an authorized factory service technician. 
 

Replacing the Dome Handle:

   

If the dome handle is broken, replacements are available.  Please contact your local MAPA Representative to obtain 
repair parts. 
 

Limited Warranty:   

MAPA will repair or replace any defective parts or workmanship of this product for a period of one year from date of 
delivery.  Damage caused by incorrect installation, alteration or improper usage is not warranted.  The failure  to install a 
wye-strainer immediately upstream of the ball valve, and/or the failure to routinely clean the mesh screen in the strainer 
may cause valve damage and will void the warranty. Recovery rights shall be limited to the total sum of the amounts paid 
for the product by the purchaser.
