What’s Included:
E5 Circulation Pump with power cord

Description:

This SilentFlo E5 circ pump replaces all previous versions of single-speed and two-speed circulation pumps.

The new E5 replaces the Watkins SilentFlo® 5000 and Silentflo 5002 circulation pumps on all Hot Spring, Tiger River & Limelight spa models from 1986 to 2018. The E5 was introduced in March of 2008 as the premier upgrade/replacement circulation pump and has had a handful of updated and thoughtful revisions since.  The compact size and flexible positioning (can mount on its side or vertical on the sidewall of the equipment compartment) has won it favor with Hot Spring dealers worldwide. This little jewel uses less electricity and moves more water per minute than all previous Silentflo pumps. When you refill your spa and power it up this “next generation” magnetic drive, it slowly ramps up to ensure that it’s well primed with water. The position of the suction/inlet is 1-11/16″ from the floor which is the same as the Silentflo 5000 & Silentflo 5002. The return/discharge is 4-1/4″ off the floor same which is also the same as the Silentflo 5000 & 5002. The impeller is accessible simply by unscrewing the top ring of the pump for easier cleaning if needed. This hot tub circulation pump draws water through a filter (1989 forward spas) and then pushes it through the heater, ozone injector (if equipped) and back into the spa through the heater return fitting or floor drain. It circulates twenty percent more gallons per minute than the Watkins Silentflo 5000 yet uses only 35 watts verses 65 watts by the Silent Flo 5000. Impressive!

Note: Some applications may require that this pump lay on its side for an easier connection to existing plumbing. It is not necessary to attach this pump to the floor of the equipment compartment.

Technical Specs: 115volts/230volts 50hz/60hz; 39W (6,000 Gallons every 24 hours)

Removal of the old circ pump

  1. Disconnect power to the spa.
  2. Access the equipment compartment.
  3. Unplug the circulation pump from the control box.
  4. If the spa is filled with water, clamp the circulation pump inlet and outlet tubing with Hose Clamp Pliers or insert wine bottle corks into the ends of the tubing.
  5. Remove the bonding wire and base bracket screws.
  6. Use pliers to slide the spring clamps located on the inlet and outlet fittings back onto the vinyl tubing.
  7. Remove the vinyl tubing from the pump inlet and outlet fittings.

Installation of the new circ pump

  1. Reverse steps 3 to 7 of the Circulation Pump Removal instructions.
  2. Check for water leaks.
  3. Reconnect power to the spa.
  4. Perform a water flow test.
  5. Check for any air in the plumbing lines. If air does not clear, bleed off the air at the closest tubing clamp.
  6. Reinstall the equipment compartment door.

  • Difficulty: easy Repair Time: 1H My spa (Hotspring Grandee) developed a leak, and it turned out that the continuous flow pump had worn out. What was interesting is that the sidewall of the tube where the water comes out of the pump had been worn to paper thin. The tube wall thickness on the other side was still about 1/8 inch thick, but after 20 years of continuous flow, the housing material was simply worn away.
