Concern 4: Leak(s)

Investigate the Leak

1. Is the leak the result of a blowout? (example: a line is completely split open- generally a major leak)

• No: Proceed to Identify the leak location.

• Yes: Proceed to Identify the cause of the Blowout.

Identify the Leak Location

1. What is leaking?

• The pump: Replace the pump seal kit. Find it here.

• A hose or fitting itself: Replace the leaking part. Find replacement parts here.

• between misting tee and nozzle: check for proper tightening. If tight, remove the nozzle and inspect the o-ring condition. O-rings can be replaced (pack of 20 MC46180).

• A connection point between a hose and a fitting: Disconnect the line from the fitting, and check for damages, burrs, or an uneven cut of the line.

i. Note: If mounting brackets are installed too close (less than 2 inches) away from misting tees, it may cause fittings to leak.

ii. If the line is damaged at the tip, it can be cut, but the positioning of system components may need to change to compensate for any significant shortening. (damaged steel tubing will require replacement)

iii. If the line is undamaged, replace the fitting. Find replacement parts here.

Identify the Cause of the Blowout

1. Inspect system installation/expansion: Having too few nozzles can lead to a blowout. Does the system match the original system design? (20-40 nozzles for 0.5GPM, 40-80 nozzles for 1GPM, or 80-160 nozzles for 2GPM)

• No: Return system to original specifications. Then return to Identify the Leak Location above, and replace the appropriate parts.

• Yes: proceed to the next step-

2. Some system designs may have shut-off valves or solenoids on output lines. If too many outputs are turned off at the same time, a blowout could result. Does this system have shut-off valves or solenoids that may have caused less than the minimum number of nozzles to be open while the pump was running?

• Yes: Take steps to ensure that the minimum number of nozzles are open while the pump is on, or consider upgrading to a Variable Frequency Drive Pump. Then return to Identify Leak Location above, and replace the appropriate parts.

• No: proceed to the next step-

3. Was the system properly winterized and de-winterized to protect the system from freeze damage?

• No: blowout likely occurred because of freeze damage. Then return to Identify the Leak Location above, and replace the appropriate parts.

• Yes: proceed to the next step-

• N/A freezing has not occurred in my area: proceed to the next step-

4. Was the air properly purged from the input, pump, and output sides of the system before it was turned on?

• No: pressurized air pockets in the system can cause severe vibration and damage which could lead to a blowout. Then return to Identify the Leak Location above, replace the appropriate parts, and purge all air from the system before operation.

• Yes: proceed to the next step-

5. Check bypass valve adjustment: Note! The Bypass Valve is set from the factory, and the setting does not change on its own. Has the bypass valve been adjusted?

• Yes: re-adjust bypass valve: Counterclockwise reduces output pressure, clockwise increases output pressure. (It is advisable to Contact a Mistcooling technical support agent through email or by scheduling a call before performing this step). Then return to Identify the Leak Location above, and replace the appropriate parts.

• No: Blowout may have occurred to some outside source of damage during installation or shipping. Blowouts due to degradation or product defect will be extremely rare. Return to Identify the Leak Location above, and replace the appropriate parts.
