What the Wayne Halo50 is and what you need before starting

The Wayne Halo50 is a submersible pump designed to move water from a sump pit or basement. It sits at the bottom of the pit, turns on when water rises to a certain level, and pumps that water out through a discharge line. Before you begin installation, gather the pump itself, a length of discharge pipe (usually 1.5 inches in diameter), a check valve, a power cord long enough to reach an outlet, and a bucket or wet/dry vacuum to remove standing water from the pit.

You will also need basic tools: a wrench or adjustable wrench, a hacksaw or PVC cutter if you need to trim the discharge pipe, and a flashlight. Read through the entire instruction manual that comes with your pump first — different models have slightly different float switch setups, and you need to know which one you have.

Key Takeaways

  • The Wayne Halo50 mounts inside a sump pit and needs a clear path for water to enter from below and a discharge line to carry water away from the house.
  • The check valve must go on the discharge line above the pump to prevent water from flowing backward into the pit when the pump stops.
  • The float switch controls when the pump turns on and off — it must move freely and not get stuck on the pump body or pit walls.
  • The pump needs a dedicated outlet or a GFCI-protected outlet within reach of the power cord, never an extension cord as a permanent solution.
  • Test the pump by pouring water into the pit slowly and watching it turn on at the correct level and shut off when the pit empties.

Prepare the sump pit and remove standing water

If your sump pit already has water in it, use a bucket or wet/dry vacuum to remove as much as you can. The pump needs to sit on the bottom of the pit, and you cannot see what you are doing if the pit is full. Leave just enough water to see the bottom clearly.

Check the pit for debris — leaves, dirt, gravel, or concrete chips can jam the pump intake. Wipe the bottom with an old cloth or paper towels. Look at the pit walls and note any cracks or damage; if water is seeping in from the sides, the pit itself may need repair before the pump will work properly. Make sure the pit is deep enough for the pump to sit fully submerged when water is at normal operating level.

Position the pump and attach the discharge line

Place the Wayne Halo50 on the bottom of the pit, centered if possible. The intake (the opening at the bottom or sides of the pump) must not be blocked by the pit wall or any debris. The float switch — a ball or arm that rises and falls with the water level — must hang freely beside the pump without touching it or the pit walls. If the float gets stuck, the pump will not turn on or off properly.

Cut or measure your discharge pipe so it reaches from the pump outlet up and out of the pit, then continues to where you want the water to go (usually outside the house, away from the foundation, or into a storm drain if your local code allows it). Attach the check valve to the pump outlet first — this one-way valve stops water from flowing backward into the pit when the pump shuts off. Then attach the discharge pipe to the check valve outlet. Use the wrench to tighten all connections hand-tight, then one more quarter turn — do not over-tighten PVC fittings or they will crack.

Secure the pump and discharge line so they do not move

As water enters the pit during a heavy rain, pressure and movement can shift the pump or pipe. Use a pump bracket or strap (many come with the pump) to anchor the pump to the pit wall or floor so it cannot tip or slide. The discharge pipe should also be secured to the house or pit wall with clips every few feet so it does not whip around when the pump starts.

Make sure the discharge line slopes downward from the pump outlet — water should flow out naturally by gravity, not pool inside the pipe. If the line has to go up before it goes down, water will get trapped and the pump will work harder than it needs to. Check that the end of the discharge line is not submerged in standing water outside, or water will flow backward into the pit when the pump stops.

Connect the power cord and test the float switch

Plug the pump into a GFCI outlet (a special outlet that cuts power if it detects a short circuit — most bathrooms and basements have them, or you can install one). The outlet must be within the length of the power cord; do not use an extension cord as a permanent fix. If the outlet is too far away, hire an electrician to install a new one closer to the pump.

Before you turn the pump on, manually lift the float switch to its highest position and release it — it should swing freely and return to its resting position without sticking. If it catches or binds, adjust the float arm or reposition the pump so the float has clear space to move.

Fill the pit and watch the pump cycle

Slowly pour water into the pit with a bucket or garden hose. Watch the water level rise and observe when the float switch rises with it. The pump should turn on automatically when the water reaches the "on" level — this is usually marked on the pump or in the manual. Listen for the motor to start and feel the discharge line to confirm water is flowing out.

Continue adding water until the pit is full, then stop and let the pump empty it. The pump should shut off automatically when the water drops to the "off" level, which is lower than the "on" level. This prevents the pump from cycling on and off constantly. If the pump does not turn on, check that the power cord is plugged in, the outlet has power (test it with a lamp), and the float switch is moving freely. If the pump turns on but no water comes out, the discharge line may be blocked or the check valve may be installed backward.

Troubleshoot common installation problems

If the pump runs but water level does not drop, the discharge line is probably blocked or kinked. Trace the entire line from the pump outlet to the end and straighten any bends. If the line is clear, the check valve may be stuck closed — turn off the pump, disconnect the discharge line, and try to blow air backward through the check valve. If no air comes out, the valve is faulty and needs replacement.

If the pump turns on and off every few seconds, the float switch is probably stuck or the pit is too small. Make sure the float moves freely and is not touching the pump body. If the pit is very small and fills quickly, you may need a pump with a larger capacity or a pit with more volume. If the pump does not turn on at all even though water is rising, check that the power cord is plugged in, the outlet works, and the float switch is not stuck in the down position.

Frequently Asked Questions

Do I need a check valve on the discharge line?

Yes. Without a check valve, water will flow backward into the pit when the pump stops, and the pump will have to remove that water again the next cycle. This wastes energy and wears out the pump faster. The check valve is a small, inexpensive part that should always be installed.

Can I use an extension cord to power the pump?

Not as a permanent solution. Extension cords are a shock hazard in wet basements and can overheat if the pump draws more power than the cord is rated for. If the outlet is too far away, have an electrician install a new GFCI outlet closer to the pump location.

What should the discharge line be made of?

PVC pipe is standard and inexpensive. Some people use flexible vinyl hose, which is easier to route around corners, but it can kink and restrict flow. Whatever you use, make sure it is rated for the pump's discharge pressure and does not get crushed or blocked.

How often should I test the pump?

Test it once after installation to confirm it works. After that, listen for it during heavy rain to make sure it turns on. Once or twice a year, pour water into the pit slowly and watch it cycle on and off to confirm the float switch is still moving freely.

What if water is coming into the pit faster than the pump can remove it?

The pump may be undersized for your basement's water problem. The Wayne Halo50 moves a certain number of gallons per hour — if groundwater or surface water is entering faster than that, the pit will overflow. You may need a larger pump, a second pump, or a solution to the water source itself, such as grading the yard away from the house or installing a sump pit cover.
