Is the system supplied water by a pressurized source or is it tank fed?
Tank-fed: Proceed to Tank-fed Water Source Inspection.
Pressurized source: Proceed to the next step-
Visually inspect the water source: Make sure the water is turned fully on. Make sure lines/hoses are free of leaks. Make sure lines/hoses are not kinked, crimped, blocked, twisted, or being squeezed by any objects pressing against them.
Not Good: address the issue and recheck the operation.
i. Good: Issue resolved.
ii. Not Good: Proceed to the next step-
Good: Proceed to the next step-
Is there any water leaking from the pump assembly when off or running?
Yes: Proceed to Concern 6: Leak(s) and address any leaks before continuing this troubleshooting chart.
No: Proceed to the next step-
Inspect water source output: Start by disconnecting the source line from the pump inlet. Is proper flow and pressure present?
Not Good: work backward down the line by disconnecting the line between the filter to the pump, the filter(s), any line between the filter and source outlet, and any garden hose between the line and source outlet, one at a time to identify the item restricting water flow. Replace as necessary. Find replacement parts here. (If the source outlet itself is restricted, a professional plumber should be contacted. The Mistcooling system is not the issue.)
Good: Proceed to the next step-
Inspect filter for debris and replacement schedule. An overdue/dirty filter may still interfere with pump operation even if some flow is present.
Not Good: replace the filter. Find filters here.
Good: Proceed to the next step-
Reconnect the known-good water source to the pump inlet, disconnect the outlet line from the pump, and turn on the pump (this step will simultaneously clear an airlock if present). Does the pump produce the proper flow of water?
No: Proceed to Inspect the Pump Unit internals.
Good: Proceed to Inspect the Output Section/Misting Line.
Check bypass valve adjustment: Note! The Bypass Valve is set from the factory, and the setting does not change on its own. If the system has been working and it suddenly stops, it is extremely unlikely that the Bypass valve is the issue unless if the valve has been adjusted. 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).
No: Proceed to the next step-
Is the pump leaking water while the pump is running?
Yes: Replace the pump seal kit. MC60560
No: Proceed to the next step-
Is the water supply a pressurized or tank-fed source?
Pressurized: Replace the solenoid valve. MC60460
Tank fed: Contact a Mistcooling technical support agent through email or by scheduling a call.
Visually inspect output lines and all connections for any physical damages such as bulges, creases, cuts, splits, leaks, etc.
Not Good: Repair/replace as necessary. (For leaks specifically, see Concern 6: Leak(s).)
Good: Proceed to the next step-
Inspect system installation/expansion: Does the system match the original system design? (10-20 nozzles for .15GPM or 20-40 nozzles for .3GPM)
No, the system has been expanded: return the system to the original specifications and recheck operation:
i. System operates properly: Issue Resolved.
ii. System still doesn’t operate properly: next step-
Yes: Proceed to the next step-
Purge air from the output line: Remove the end plug (or last nozzle) from the misting line, connect the misting line to the pump outlet, and turn the pump on until a steady stream of water, free of air pockets, comes out. Reinstall the end plug/last nozzle and check the operation.
Steps could not be completed. No water comes out with the end plug/last nozzle removed: Remove the misting line from the pump outlet, backflush line with compressed air, and perform this step again. If the step still cannot be completed, Contact a Mistcooling technical support agent through email or by scheduling a call.
Misting returns to normal: Issue resolved.
There is still no mist present or misting is uneven. Remove all misting nozzles and use our Mistcooling Nozzle Cleaner: MC46220. In severe cases, nozzles may still need replacement. If cleaning or replacement of nozzles still does not resolve the issue: Contact a Mistcooling technical support agent through email or by scheduling a call.
Does the arrangement of the tank and pump still match the original system design? (Tank should be elevated about 1 foot above pump- if possible).
No: Please make sure the layout fits the original design. Does proper operation resume?
i. Yes: Issue Resolved.
ii. No: Proceed to the next step-
Yes: Proceed to the next step-
Is the tank full and properly ventilated?
No: Fill the tank and verify proper ventilation. Does proper operation resume?
i. Yes: Issue Resolved.
ii. No: Proceed to the next step-
Yes: Proceed to the next step-
Verify that the is no air caught in the supply line between the tank and the pump inlet: (Disconnect the supply line from the pump inlet and verify that water drains out of the supply line with no air present.)
Water comes out with air bubbles: Allow water to flow until the air is purged, then proceed to Step 6 of Inspect the Water Source.
Water does not flow or flow is restricted: Address the restriction between the tank and of end of the supply hose, then proceed to Step 6 of Inspect the Water Source.
Water flows freely with no air: Proceed to Step 6 of Inspect Water Source.
