| + | Ideally during daily rig checks, but **at minimum** once a week on tool day, the relief valve shall be exercised all the way in and out, with the pump under pressure, to prevent it from seating in one position.

| Lubrication of the discharge gate valves is most important. Some manufacturers provide grease fittings for this purpose. There are some ball-type gate valves, however, for which no provision has been made. It is recommended that light oil such as WD-40 be used to lubricate the gate valves. | Lubrication of the discharge gate valves is most important.

| - | ====Flushing and Cleaning Pumps==== | + | ===The Pump Flush Process=== |
| - | * Pumps shall be back-flushed once a month and noted on form 300-3. | + | This process is to flush out the rust and should |
| - | * Pumps will be flushed from a hydrant after drafting\\ \\ | + | Start on driver side (Left) pump panel: |
| - | * The back flushing of the pump is conducted by connecting a 2.5" or 3" hose, supplied from a hydrant, | + | * Make sure the Tank Fill and Tank to Pump are open (pulled all the way out). |
| - | * Big way valves and caps are removed. | + | * Open the Master Drain ALL THE WAY. Leave open for the entirety |
| - | * The hydrant is opened, forcing water into the top of the pump, flowing water and any debris out of the big way ports. | + | * Open 2.5in Auxiliary Intake half way (to clear the ball valve) until rust clears, then fully open until it clears the rest. Close when water clear. If water does not clear, you should flush the whole system. |
| - | * This should be done for a minimum of five (5) minutes. | + | |
| - | \\ | + | Now move to the Officer side (Right) pump panel: |
| - | ====Drafting Water==== | + | * Go to the 2.5in Auxiliary Intake, open half way (again, this is to clear the ball valve itself of rust) until rust clears. Then open all the way. Close when water is clear of rust. |
| + | |||
| + | Back to the Driver side (Left) pump panel: | ||
| + | * Hook the hydrant to the 2.5in Auxiliary Intake. Your Inlet valve will be your control during this process. | ||
| + | * Open Big Way and drain the remainder of the system. | ||
| + | * Close Tank to Pump (pushed all the way in) If this is not closed, it will ruin the valve. | ||
| + | * Keep Tank Fill open. | ||
| + | * Open hydrant, then open the 2.5in Auxiliary Intake. | ||
| + | * Close the Big Way | ||
| - | Drafting from ponds, creeks, etc., for training purposes is not recommended. Sand, silt, and dirt can damage pumps and priming pumps. Draft from these sources only in emergency situations. | + | Back on the Officer side (Right) pump panel: |
| + | * There is no need to open the LDH Intake | ||
| + | * Open 2.5in Discharge half way until water clears and then open fully, close when water runs clear. | ||
| + | * Open LDH Discharge half way until water clears and then open fully, close when water runs clear. | ||
| + | Back to Driver Side (Left) pump panel: | ||
| + | * You do not need to open deck gun and pre-connects, | ||
| + | * Open 2.5in Front Discharge valve half way until water clears and then open fully, close when water runs clear. | ||
| + | * Open 2.5in Rear Discharge valve half way until water clears and then open fully, close when water runs clear. | ||
| + | * Close Master Drain. | ||
| + | * Fill tank. Overfill out the top for 1 minute to clear that. | ||
| + | * Close the 2.5in Auxiliary Intake and disconnect from the hydrant to complete the process. | ||
