Replacing an Existing Pump

Deep Well
Risk of electric shock. Can shock, burn or kill. Disconnect power to pump before working on pump or motor.

  1. Drain and remove the old pump. Check pipe for scale, lime, rust, etc., and replace it if necessary.
  2. Install the control valve and pressure gauge in the pump body.
  3. If your old pump has the suction pipe (the larger port – see Figure 2) below the drive port, you will need to install flexible pipe between the well head and the pump so that the connection will be correct. NOTICE Your old ejector (in the well) may not be properly matched to your new pump. If the pump does not perform properly, we recommend that you install Flotec ejector kit FP4800.
  4. Install the pump in the system. Make sure that all pipe joints in the suction pipe are air-tight as well as water tight. If the suction pipe can suck air, the pump will not be able to pull water from the well.
  5. Adjust the pump mounting height so that the plumbing connections do not put a strain on the pump body. Support the pipe so that the pump body does not take the weight of piping or fittings.

You have just completed the good plumbing for your new deep-well jet pump. Please go to Page 8 for discharge pipe and tank connections.

Shallow Well
Risk of electric shock. Can shock, burn or kill. Disconnect power to the pump before working on the pump or motor.

  1. Drain and remove the old pump. Check the old pipe for scale, lime, rust, etc., and replace it if necessary.

  2. Install the control valve and pressure gauge in the pump body.

  3. Install ejector kit FP4855 with a Series 4200, or kit FP4875 with a Series 4300 pump (kits are sold separately). Follow the instructions provided with the kit. Be sure to align the venturi with the top hole on the front of the pump.
    NOTICE Always replace the ejector when replacing the pump in a shallow well installation.PENTAIR-FP4200-Series-Convertible-Deep-Well-Jet-Pumps-fig-
\(3\)

  4. Install the pump in the system. Make sure that all pipe joints in the suction pipe are air-tight as well as watertight. If the suction pipe can suck air, the pump will not be able to pull water from the well.

  5. Adjust the pump mounting height so that the plumbing connections do not put a strain on the pump body. Support the pipe so that the pump body does not take the weight of piping or fittings.

You have just completed the good plumbing for your new shallow well jet pump. Please go to Page 8 for discharge pipe and tank connections.

New Shallow Well Installation

Well Point Installation

  1. Install the control valve and pressure gauge in the pump body.
  2. Install ejector kit FP4855 with a Series 4200 pump, or kit FP4875 with a Series 4300 pump (kits are sold separately). Follow the instructions provided with the kit. Align the venturi with the top hole on the front of the pump.
  3. Drive the well, using “drive couplings” and a “drive cap”. “Drive fittings” are threaded all the way through and allow the pipe ends to butt against each other so that the driving force of the maul is carried by the pipe and not by the threads. The ordinary fittings found in hardware stores are not threaded all the way through the fitting and can collapse under impact. “Drive fittings” are also smoother than standard plumbing fittings, making ground penetration easier.
  4. Mount the pump as close to the well as possible.
  5. Use the fewest possible fittings (especially elbows) when connecting the pipe from the well point to the pump suction port. The suction pipe should be at least as large as the suction port on the pump (include a check valve – see Figure 5). Support the pipe so that there are no dips or sags in the pipe, so it doesn’t strain the pump body, and so that it slopes slightly upward from the well to the pump (high spots can cause air pockets which can air lock the pump). Seal the suction pipe joints with PTFE pipe thread sealant tape or a PTFE-based pipe joint compound approved for use on PVC. Joints must be air- and water-tight. If the suction pipe can suck air, the pump cannot pull water from the well. If one well point does not supply enough water, consider connecting two or three well points to one suction pipe.PENTAIR-FP4200-Series-Convertible-Deep-Well-Jet-Pumps-fig- \(5\)

You have just completed the suction piping for your new shallow well jet pump. Please go to Page 8 for discharge pipe and tank connections.

Cased Well Installation, 2” or Larger Casing

  1. Install the control valve and pressure gauge in the pump body.
  2. Install ejector kit FP4855 with a Series 4200 pump, or kit FP4875 with a Series 4300 pump (kits are sold separately). Follow the instructions provided with the kit. Align the venturi with the top hole on the front of the pump.
  3. Mount the pump as close to the well as possible.
  4. Assemble the foot valve, strainer, and well pipe. Make sure that the foot valve works freely.
  5. Lower the pipe into the well until the strainer is five feet above the bottom of the well. It should also be at least 10 feet below the well’s water level while the pump is running in order to prevent the pump from sucking air. Install a sanitary well seal.
  6. Install a priming tee, priming plug, and suction pipe to the drop pipe. If the distance from the well to the pump is substantial, add a priming tee at the pump. Connect the pipe from the well to the pump suction port, using the fewest possible fittings – especially elbows – as fittings increase friction in the pipe. The suction pipe should be at least as large as the suction port on the pump. Support the pipe so that there are no dips or sags in the pipe, so it doesn’t strain the pump body, and so that it slopes slightly upward from the well to the pump (high spots can cause air pockets which can air lock the pump). Seal the suction pipe joints with PTFE pipe thread sealant tape or a PTFE-based pipe joint compound. Joints must be air- and water-tight. If the suction pipe can suck air, the pump cannot pull water from the well.PENTAIR-FP4200-Series-Convertible-Deep-Well-Jet-Pumps-fig- \(6\)

  3. The pump should be installed as close to the water as possible, with the fewest possible fittings (especially elbows) in the suction pipe. The suction pipe should be at least as large as the suction port on the pump.
  4. Assemble a foot valve and suction pipe. Make sure that the foot valve works freely. Use PTFE pipe thread sealant tape or a PTFE-based pipe joint compound on threaded pipe joints. Protect the foot valve assembly from fish, trash, etc, by installing a screen around it.
  5. Lower the pipe into the water until the strainer is five feet above the bottom. It should also be at least 10 feet below the water level in order to prevent the pump from sucking air.
  6. Install a priming tee, priming plug, and suction pipe to the pump. Support the pipe so that there are no dips or sags in the pipe, so it doesn’t strain the pump body, and so that it slopes slightly upward from the well to the pump (high spots can cause air pockets which can air lock the pump). Seal the suction pipe joints with PTFE pipe thread sealant tape or a PTFE-based pipe joint compound. Joints must be air- and water-tight.

  5. Install a sanitary well seal and connect the ejector piping to the pump. Use steel nipples through the good seal with flexible poly pipe to avoid crushing the plastic pipe when tightening the seal.
  6. Support the pipe so that there are no dips or sags in the pipe, so it doesn’t strain the pump body, and so that it slopes slightly upward from the well to the pump (high spots can cause air pockets which can air lock the pump). Seal the suction pipe joints with PTFE pipe thread sealant tape or a PTFE-based pipe joint compound. Joints must be air- and water-tight. If the suction pipe can suck air, the pump cannot pull water from the well.PENTAIR-FP4200-Series-Convertible-Deep-Well-Jet-Pumps-fig- \(10\)

You have just completed the plumbing for your new double-pipe deep well jet pump. Please go to Page 8 for discharge pipe and tank connections.

  4. Run two pipes (one smaller drive pipe, one larger suction pipe) from the well to the pump. Support the pipe so that there are no dips or sags in the pipe, so it doesn’t strain the pump body, and so that it slopes slightly upward from the well to the pump (high spots can cause air pockets which can air lock the pump). Seal the suction pipe joints with PTFE pipe thread sealant tape or a PTFE-based pipe joint compound. Joints must be air- and water-tight. If the suction pipe can suck air, the pump cannot pull water from the well.PENTAIR-FP4200-Series-Convertible-Deep-Well-Jet-Pumps-fig- \(11\)

You have just completed the plumbing for your new single-pipe deep well jet pump. Please go to Page 8 for discharge pipe and tank connections.

Discharge Pipe and Pressure Tank Connections

Pre-Charge Tank Connection

  1. Install a close nipple and a tee in the pump discharge port. The pipe size must be at least as large as the discharge port. Run a pipe or reinforced hose from one arm of the tee to the port on the pre-charged tank.
  2. Install a second close nipple and tee with a relief valve in the tee.
  3. Connect the other end of the second discharge tee to your plumbing system.
  4. Check the pre-charge of air in the tank with an ordinary tire gauge. The pre-charge should be 2 PSI less than the cut-in setting of the pump’s pressure switch. The pre-charge is measured when there is no water pressure in the tank. Your new pump has a 30/50 PSI switch, so adjust the tank pre-charge pressure to 28 PSI.PENTAIR-FP4200-Series-Convertible-Deep-Well-Jet-Pumps-fig- \(12\)

You have just completed the tank connection for your jet pump.

Standard Tank Connection

  1. Install a close nipple and a tee in the pump discharge port. Mount a relief valve in one arm of the tee.
  2. Install a second close nipple and tee in the open arm of the first tee. Put a priming plug in one arm of the second tee.
  3. Run a pipe from the open arm of the second tee to the inlet port of your tank. The pipe size must be at least as large as the pump discharge port.
  4. Remove the 1/8” NPT pipe plug from the pump Air Volume Control (AVC) port. Run tubing from the pump’s AVC port to the port on the AVC mounted on the tank. See instructions provided with tank and AVC for details.

You have just completed the tank connection for your jet pump.

Sealing Pipe Joints
Use only PTFE pipe thread sealant tape or PTFE-based joint compounds for making all threaded connections to the pump itself. Do not use pipe joint compounds on plastic pumps: they can react with the plastic in pump components. Make sure that all pipe joints in the suction pipe are air tight as well as watertight. If the suction pipe can suck air, the pump will not be able to pull water from the well.

Electrical

WARNING
Risk of electric shock. Can shock, burn or kill. Disconnect power before working on pump, motor, pressure switch, or wiring.

Motor Switch Settings
NOTICE 1/2 HP motors are dual voltage and are factory set to 115 V. 3/4 & 1 HP motors are also dual voltage, but are factory set to 230 V.

Preparing to Start the Pump – Deep Well

CAUTION

Risk of burns
Never run the pump dry. Running a pump without water may cause the pump to overheat, damaging the seal and possibly causing burns to the person handling the pump. Fill the pump with water before starting.

WARNING

Risk of explosion and scalding
Never run the pump against closed discharge. To do so can boil water inside the pump, causing hazardous pressure in the unit, risk of explosion and possibly scalding the person handling the pump.

  1. Open the control valve as far as possible. Then remove the priming plug from the pump and fill the pump, fill all piping between the pump and the well, and make sure that all piping in the well is full. If you have also installed a priming tee in the suction piping, remove the plug from the tee and fill the suction piping.
  2. Replace all fill plugs and close the control valve completely.
  3. Power on! Start the pump and watch the pressure gauge. The pressure should build rapidly to 50 PSI as the pump primes.
  4. Open several faucets in the residence to permit water flow and to release trapped air. After 2 or 3 minutes, the gauge should show pressure. If not, stop the pump, remove the fill plugs, reopen the control valve, and refill the pump and piping. You may have to repeat this two or three times in order to get all the trapped air out of the piping. Don’t forget to close the control valve each time before you start the pump.
  5. When water pressure has built up and is maintained by the pump, slowly open the control valve while watching the pressure gauge needle. Continue opening the valve until the valve is fully open or you see the pressure gauge needle start to flutter. If the needle starts to flutter, slowly close the valve just enough to stop the flutter. Your pump is now operating at peak efficiency.
  6. Close all open faucets. After the pump has built up pressure in the system and shut off, check the pressure switch operation by opening a faucet or two and running enough water out to bleed off the pressure until the pump starts. The pump should start when the pressure drops to 30 PSI and stop when the pressure reaches 50 PSI. Run the pump through one or two complete cycles to verify the correct operation. This will also help clean the system of dirt and scale dislodged during installation.PENTAIR-FP4200-Series-Convertible-Deep-Well-Jet-Pumps-fig- \(20\)

Congratulations on a successful installation. If you were unsuccessful, please refer to Troubleshooting or call our customer service technical staff.

Preparing to Start the Pump – Shallow Well

CAUTION

Risk of burns
Never run the pump dry. Running a pump without water may cause the pump to overheat, damaging the seal and possibly causing burns to the persons handling the pump. Fill the pump with water before starting.

WARNING

Risk of explosion and scalding
Never run the pump against closed discharge. To do so can boil water inside the pump, causing hazardous pressure in the unit, risk of explosion, and possibly scalding the person handling the pump.

  1. Open the control valve as far as possible. Then remove the priming plug from the pump and fill the pump, fill all piping between the pump and the well, and make sure that all piping in the well is full. If you have also installed a priming tee in the suction piping, remove the plug from the tee and fill the suction piping.
  2. Replace all fill plugs. Leave the control valve open (in a shallow well installation, the control valve always stays open).
  3. Power on! Start the pump. The pump should pump water in two or three minutes.
  4. If you don’t have water after 2 or 3 minutes, stop the pump and remove the fill plugs. Refill the pump and piping. You may have to repeat this two or three times in order to get all the trapped air out of the piping. The control valve remains open throughout this procedure.
  5. After the pump has built up pressure in the system and shut off, check the pressure switch operation by opening a faucet or two and running enough water out to bleed off the pressure until the pump starts. The pump should start when the pressure drops to 30 PSI and stop when the pressure reaches 50 PSI. Run the pump through one or two complete cycles to verify the correct operation. This will also help clean the system of dirt and scale dislodged during installation.

Congratulations on a successful installation. If you were unsuccessful, please refer to Troubleshooting or call our customer service technical staff.

Troubleshooting

Symptom Possible Cause(s) Corrective Action

Motor will not run

Ejector or impeller is plugged| Clean ejector or impeller.
Check valve or foot valve is stuck shut| Replace check valve or foot valve.
Pipes are frozen| Thaw pipes. Bury pipes below frost line. Heat pit or pump house.
Foot valve and/or strainer are buried in sand or mud| Raise foot valve and/or strainer above bottom of water source. Clean foot valve and strainer.
Water level is too low for shallow well setup to deliver water| A deep well jet will be needed if your well is more than 25’ (7.6M) depth to water.
Pump does not deliver water to full capacity (Also check point 3 immediately above)| Water level in well is lower than estimated| A new nozzle and venturi combination may be needed.
Steel piping (if used) is corroded or limed, causing excess friction| Replace with plastic pipe where possible, otherwise with new steel pipe.
Piping is too small in size| Use larger piping.

Pump delivers water but does not shut off or pump cycles too frequently

| Pressure switch is out of adjustment or contacts are welded together| DISCONNECT POWER; adjust or replace pressure switch.
Faucets have been left open| Close faucets.
Venturi, nozzle or impeller is clogged| Clean venturi, nozzle or impeller.
Standard pressure tank is waterlogged and has no air cushion| Drain tank to air volume control port. Check AVC for defects. Check all connections for air leaks.
Pipes leak| Check connections.
Foot valve leaks| Replace foot valve.
Pressure switch is out of adjustment| Adjust or replace pressure switch.

Air charge too low in pre-charged tank

| DISCONNECT POWER and open faucets until all pressure is relieved. Using tire pressure gauge, check air pressure in tank at valve stem located on the tank. If less than pressure switch cut-in setting (30-50 PSI), pump air into tank from outside source until air pressure is 2 PSI less than cut-in setting of switch. Check air valve for leaks (use soapy solution) and replace core if necessary.

Air spurts from faucets

| Pump is picking up prime| When pump has picked up prime, it should pump solid water with no air.
Leak in suction side of pump| Suction pipe is sucking air. Check joints for leaks with shaving cream.
Well is gaseous| Consult factory about installing a sleeve in the well.
Intermittent over-pumping of well. (Water drawn down below foot valve.)| Lower foot valve if possible, otherwise restrict pump discharge.
