Upload a photo of the disconnected motor leads

Visual inspection of the cam gear and microswitches for any wear

Replacement pilot valve drive motor assembly installed and gears and assembly are properly engaged

Upload a photo of the securely tightened screws and reconnected motor leads

Pilot valve body assembly reinstalled in the enclosure

Backwash Flow Control nipple replaced with compression fitting downstream of the flow washer

Flexible tubing connected to the compression fitting in the side of the Backwash Flow Control nipple

Clean-out plug inserted and tightened

Flow patterns for the regeneration and service cycles are governed by the individual diaphragm valves. These valves close when under pressure and open when pressure is vented. Each is identified by a number cast on the front of the main valve body.

Control tubing connects each numbered valve with the MVP Controller.

NOTE: #17 is always closed on multiple tank systems. * See note below about port conversion.

NOTE: The system provided may utilize an older version of pilot valve and/or Brunermatic Valve port numbering. Evidence of the old numbering scheme is noted by the use of port number 17 on the pilot valve and/or Brunermatic valve.

If the numbering scheme of the pilot valve does not completely match the Brunermatic valve, the following chart should be referred to for conversion purposes.

Remove clean-out plug and inspect the flow washer area (Figure 108)

Remove any foreign material lodged in or near the flow washer(s) (Figure 109)

NOTE: AVOID USING A SHARP OBJECT WHICH MIGHT CUT OR DAMAGE THE RUBBER FLOW WASHER(S). SHOULD IT NOT BE POSSIBLE TO CLEAR THE CONTROLLER THROUGH THE CLEAN OUT PLUG, REMOVAL OF THE FLOW CONTROL NIPPLE WILL BE REQUIRED TO GAIN BETTER ACCESS TO THE FLOW WASHER AREA.

If removal of the Backwash Flow Control nipple is necessary, disconnect the flexible tubing from the compression fitting.

Carefully separate the nipple from both the drain line and the Brunermatic valve (Figure 110). Inspect and clean flow washer(s) (Figure 111 and Figure 112)

Refer to steps 1 thru 3 under 'Pilot Valve Spool Removal & Replacement' on page 71.

Mark and remove all pilot valve tube connections from the pilot valve body.

Disconnect the four quick connect wire leads from the microswitches.

Disconnect the two motor leads from the circuit board. See Figure 115 and Figure 116.

Remove the 2 large panhead screws with nuts located at the bottom of the enclosure that secure the pilot valve body assembly. The pilot body assembly will now separate from the enclosure.
