Little Giant Pump Installation Checklist: Sewage Pumps, Effluent Pumps, V20 Pressure Washer, Welders, and Rhino Ratchet Straps

I've been handling pump and job-site equipment orders for 11 years. I've personally made—and documented—9 significant mistakes, totaling roughly $14,700 in wasted budget. Now I maintain our team's checklist to prevent others from repeating my errors.

This checklist is for B2B crews handling little-giant equipment, especially little giant sewage pump installation and little giant effluent pumps. It also covers three job-site items that cause avoidable delays: a v20 pressure washer, who owns welders, and how to release rhino ratchet straps. There are 7 steps. Work them in order. If you skip step 3, you'll probably pay for it later.

Step 1: Lock the scope and the landed price

Before you order anything, confirm pump type, basin size, discharge size, voltage, phase, head, and float style. Little giant sewage pump installation and little giant effluent pumps are not interchangeable. Sewage pumps handle solids; effluent pumps move greywater with smaller solids. I ordered an effluent pump for a sewage basin in 2019. It looked fine on the invoice. The basin filled, the float kicked, and the pump clogged in three days. $1,100 in parts and labor, plus a callback.

From the outside, the lowest quote looks like the best deal. The reality is that the quote often excludes freight, liftgate, discharge kit, check valve, basin, labor, controls, and disposal. I've learned to ask what's NOT included before what's the price. Get a final landed number in writing. Per FTC guidelines (ftc.gov), warranty and performance claims must be truthful and substantiated, so don't accept vague promises like it will run forever without service. No pump is maintenance-free. Plan maintenance.

Surface illusion: People assume the lowest quote means the vendor is more efficient. What they don't see is which costs are being hidden or deferred.

Step 2: Measure the actual site, not the old pump

Take the old model number, but don't trust it as a spec. Measure the basin diameter, depth, discharge height, and available float clearance. Check voltage and breaker size. The little-giant nameplate is a starting point, not a guarantee. I've seen replacements fail because the old pump was oversized for the basin and short-cycled. The float was hitting the lid. That was a $450 mistake in labor and a same-week return.

This was true 15 years ago when replacing like-for-like usually worked. Today, basins and codes change. A pump that fit in 2010 may not meet current venting, alarm, or check-valve requirements. Legacy myth: local is always faster. Not if the local counter doesn't stock the float or discharge kit. A well-organized remote vendor can beat a disorganized local one.

Measure twice. I usually say the discharge height is 8 feet—no, 9 feet in our area, because we forget the check valve, elbow, and pipe friction. Add the vertical lift plus fittings. That number decides the pump curve you need.

Step 3: Stage tools and shared equipment before the crew arrives

This is the step most people skip. If the pump is strapped to a pallet, learn how to release rhino ratchet straps before you cut anything. Release the tension slowly. Keep your face and hands out of the strap path. Open the ratchet handle fully, then feed the strap back through. I once cut a strap because I was in a hurry. The pump shifted, cracked a discharge flange, and cost $200 in parts. Not worth it.

If you're cleaning the basin area, a v20 pressure washer can save time. But verify the water source, power source, and GFCI. Don't blast the pump seals, motor housing, or electrical connections directly. Pressure washing is for the floor and walls, not the pump. I've also seen crews pressure-wash a control panel and then wonder why the float alarm failed.

If the job needs brackets or repairs, settle who owns welders and who is certified to use them before the crew shows up. Is the welder rented, owned by the site, or owned by your shop? That affects insurance, hot-work permits, and lockout/tagout. Don't assume. I've had a welder show up with no paperwork and delay a job by two days.

Step 4: Verify power, controls, and alarm

Before the pump goes in, check the breaker, GFCI, piggyback plug, float switch, and high-water alarm. Test the alarm manually. Most people test the pump and skip the alarm. That's the one that tells you the pump failed at 2 a.m. The alarm is not optional on a sewage basin, especially in a commercial space.

Confirm the control voltage. A 120V pump on a 230V circuit will not end well. Check the cord length. If it's too short, don't use an extension cord unless the manufacturer allows it. I've seen a maintenance tech splice a cord with wire nuts and tape. That failed inspection, and the redo cost $300 plus a delay.

Step 5: Set the pump and discharge correctly

Set the pump on a solid, level surface. Don't let it sit in sludge or gravel. For a little giant sewage pump installation, check the impeller clearance and make sure the float moves freely. Install the check valve in the right direction. Use pipe dope or Teflon tape properly—too much tape can shred and jam the impeller. I've had that happen. It looked like a pump failure. It was an installation failure.

For little giant effluent pumps, the same rules apply, but solids handling is different. Match the pump to the effluent. If the basin receives laundry or kitchen waste, you may need a different pump or a filter. Don't guess. Call the manufacturer with the model and serial number. Support exists for a reason.

Step 6: Test with water, not assumptions

Fill the basin with clean water. Run the pump through a full cycle. Watch the float, listen for cavitation, and check the amp draw against the nameplate. Verify the check valve holds. If the pump short-cycles, adjust the float or basin volume. If it runs dry, stop and fix the float.

Test the high-water alarm and the backup system if there is one. Record the time it takes to empty the basin. That baseline helps you diagnose problems later. The best part of doing this test: no 3 a.m. emergency call because you caught the issue at 3 p.m.

Step 7: Document, hand off, and close the money loop

Take photos of the nameplate, serial number, wiring, discharge, float settings, and alarm. Write down the model, voltage, amperage, and installation date. Give the customer a simple handoff sheet. Tell them what to check monthly: float movement, alarm test, discharge for leaks, and breaker status. Don't tell them the pump will last forever without service. Tell them what to do when it does.

On pricing, keep it transparent. The vendor who lists all fees upfront—even if the total looks higher—usually costs less in the end. Hidden fees show up as freight, liftgate, after-hours labor, disposal, or warranty exclusions. Ask for the final invoice to match the quote. If it doesn't, you have a problem.

I have mixed feelings about rush fees. On one hand, they feel like gouging. On the other, I've seen the operational chaos rush orders cause. Sometimes the premium is real. But it should be disclosed before the order, not after.

Common Mistakes to Avoid

• Ordering an effluent pump for a sewage basin, or the reverse. This is the most expensive mistake I've made.
• Skipping the check valve or installing it backward.
• Forgetting liftgate service and then trying to unload a pump by hand.
• Cutting rhino ratchet straps instead of releasing them slowly.
• Assuming who owns welders without checking paperwork and certification.
• Pressure-washing pump seals or control panels with a v20 pressure washer.
• Accepting a low quote without asking what's excluded.
• Testing the pump but not the alarm.

This checklist won't make you look like a hero. It will keep you from looking like the person who made the $1,100 mistake. At least, that's been my experience with light commercial and residential pump work. Scope it, stage it, test it, document it. Then move on to the next job.
