Pedestal sump pumps

 

The pedestal pump is designed for use in home to draw water from sumps. It is usually equipped with an 8-ft long, 3-prong grounding type power cord. Motor is air cooled; it is not designed to operate under water. The pump id operated using a float switch that is provided for automatic pump operation.

For purposes of preserving the aquatic life this pump is not suitable for use in places where there is some aquatic life.

A pedestal sump pump requires a ground fault circuit interrupter.

One should be aware that this pump is for use on 120 Volt, 60 Hz and 15 Amp single phase source and is equipped with a three conductor cord and a three prong grounding plug.

 

 

Pedestal pump Installation

  1. Install pump in a sump pit with minimum size as shown. Construct sump pit of tile, concrete, steel or plastic.
  2. Locate unit on a solid, level foundation. Do not place pump directly on clay, earth, gravel or sandy surface. These surfaces contain small stones, gravel, sand, etc. that may clog or damage the pump and cause pump failure.
  3. Thread check valve (not included) into pump body carefully to avoid stripping or cross threading.
  4. Connect around a quarter inch rigid pipe to rubber boot on check valve. Reverse boot for one inch diameter pipe and tighten hose clamps.
  5. Protect electrical cord from sharp objects, hot surfaces, oil and chemicals. Avoid kinking the cord and replace damaged cords immediately.
  6. A sump pit cover must be installed to prevent debris from clogging or damaging the pump.
  7. Insert the float switch cord plug directly into a 120 volt outlet

Adjusting and Testing pedestal pump

Tis is usually important so as to know whether your pump is in good condition before starting to use it.

  1. First the sump is filled with water.
  2. Then the rubber grommet is adjusted into a permanent position on float rod so that the pump switches on with an approximate level of fourteen of water in the sump.
  3. While the pump is draining the pit, verify that the discharge piping is carrying the water to a point several feet away from the foundation.
  4. If the pump discharge line is exposed to freezing temperature, the exposed line must be pitched to drain. This is because trapped water will freeze and damage the pump.

Safety rules to observe with pedestal pump

  1. If repairs are required, see troubleshooting chart.
  2. If the motor is disassembled prior to expiration of warranty will void the warranty.
  3. Keep pump inlet clean and free of all foreign objects and inspect annually. This is because a clogged inlet will damage pump.
  4. Check pump monthly for proper operation.

NOTE: A pump that has a tripped thermal protector may start suddenly!

Symptom Possible, their Cause(s) and corresponding Corrective Action

  1. Pump will not start

Causes:

  1. Blown fuse.
  2. Low line voltage.
  3. Defective motor.
  4. Defective switch.
  5. Impeller.
  6. Float obstructed.

Corrective Action:

  1. If blown, replace with proper sized fuse or reset breaker.
  2. If voltage is under 108 volts, check wiring size.
  • Replace motor or pump.
  1. Replace switch.
  2. If impeller will not turn, remove housing and remove blockage.
  3. Make sure float moves freely up and down.
  1. Pump start and stops too often

Causes:

  1. Back flow of water from piping.
  2. Float out of adjustment.

Corrective Action:

  1. Install or replace check valve.
  2. Adjust grommet.
  1. Pump will not shut off or thermal protector turns off

 

Causes:

  1. Defective switch.
  2. Obstacle in piping.
  • Float obstructed.

Corrective Action:

  1. Replace switch.
  2. Remove pump and clean pump and piping.
  • Make sure float moves freely up and down.

 

  1. Pump operates but delivers little or no water

Causes:

  1. Low line voltage.
  2. Plugged impeller.

Corrective Action:

  1. If voltage is under 108 volts, check wiring size.
  2. Clean out impeller.
