Liberty Pumps P382LE41 Pro380 Sewage Pump System Review and P382LE51 Comparison

If you have a septic tank, a toilet in the basement, or any other kind of below-grade sewage system, you’re not going to be able to take advantage of a gravity drain line, and you’re going to need a sewage pump. There are a lot of options out there to consider for homeowners, landlords, and small business owners, and each promises the sea and sky. But we’ve learned that going cheap often means frequent, fast, and not at all cheap failures to clean up and pay for (often during emergency billing hours). We prefer jobs done quickly and for the long term, which is why we frequently only recommend either sewage ejector pumps installed via pre-assembled systems or direct upgrades to sewage grinder pumps. In fact, many licensed plumbers will only install pre-assembled systems simply because the reliability of individual pumps in a patchwork of pipes, floats, and basins simply can’t compare. And a good grinder will beat even the best pre-assembled ejector system.

That said, you might not need a sewage grinder pump like the Liberty Pumps PRG101A for your home, rental, or business. If you’ve got family, tenants, customers, or employees who only flush toilet paper and human waste, you’ll be just fine with an ejector pump. But to get as many years as possible out of a sewage ejector pump, you’ll want something pre-assembled like the Liberty Pumps P382LE51 or its slightly less powerful sibling, the Liberty Pumps P382LE41 Simplex Sewage System. It’s just as easy to set up, just as reliable, and just a little cheaper. Our full review is below, and you can buy it here.

Key Features of the Liberty Pumps P382LE41 Simplex Sewage System (60 Second Summary)

The Liberty Pumps P382LE41 is a pre-assembled residential sewage ejector package with a shallow system design. It can also be used in light business settings. Powered by the LE41A sewage pump, it delivers 4/10 horsepower and has an adjusted maximum flow rate of 7,640 gallons per hour (124 gallons per minute) with a max head of 19 feet. It includes the standard Liberty Pumps3 year warranty and is 24 inches tall with a base diameter of 24-3/8 inches and a widest diameter of 27-5/8 inches. The system arrives fully assembled weighing 60 pounds.

The P382LE41, like other members of the Pro380 series, is optimized for installation in difficult soil environments due to requiring shallower burial than Pro370 series systems. It can pass solids up to 2 inches in diameter and uses 115 volts single phase AC at 12 amps at full load and 22.5 locked rotor amps. Thermal overload protection shuts the motor down at 221F and the motor will pump liquids at up to 140F. The pump uses an automatic mechanical wide angle float and a 2 inch FNPT discharge.

The P382LE41 tops out at 7,680 GPH at zero feet (slightly less than the standalone LE41A), which drops to 5,760 GPH at 10 feet and shuts off at the max head of 19 feet. The system includes the QuickTree float design, which permits access, removal, and replacement of the float switch from a vertical seal in the basin without impacting the pump or plumbing. The pump is fixed within a 41 gallon polyethylene basin with a capacity 40% larger than that in 18 inch x 30 inch basins, which reduces on/off cycles in both the pump and switch, increasing the lifespan of both. The P382LE41 ships fully assembled and includes a plastic transparent cover to protect the top from rough-in and masonry work.

How Does the Liberty Pumps P382LE41 Compare to the Liberty Pumps P372LE51 and PRG101A?

The main differences between the P382LE41 and 51 are in power, pumping speeds, max head, and price. The PE382LE51 is stronger (.5 hp vs .4 hp), faster (8,400 GPH vs 7,680 GPH), pumps to a higher head (24 feet vs 19 feet), and costs somewhat more. In practical use, most of these differences will be negligible except for the max head, which will only be noticeable if you’re pushing either pump close to its limits. Reliability is the same between both pumps; you can expect up to 20 years of functionality.

The core difference between the P382LE41 and the PRG101A is that the latter is a grinder pump rather than just an ejector pump, which means it will be able to handle a wide range of difficult solids that would simply jam or damage the LE41A inside the P382LE41. If you can’t afford downtime or pump damage due to the potential of people flushing towels, rags, feminine hygiene products, and other things that shouldn’t be flushed but frequently are, save your money and move directly to the PRG101A. It’ll additionally provide a much stronger motor (1 hp vs .4 hp) and more than twice the max head at 50 feet compared to 19 feet.

Installing the P382LE41 is essentially identical to the process for the P372LE51, P382LE51, and P372LE41; just follow the instructions, take your time (about 7 hours), and make sure you have extra tubing, check valves, ball valves, and couplings handy. As with most sewage ejector pump installations, you simply run a main line in (e.g., a 2 inch or 3 inch line) and run a 2 inch discharge and 2 inch vent out. The float arrives pre-set in an optimal position in the basin. The main complaint we frequently come across is that the pump is often out of place in the enclosure upon arrival. In some cases, it was mildly connected, while in others it was placing pressure on the riser pipe or on the basin lead seal. Don’t be afraid to call customer service if anything arrives broken on arrival.

Noise-wise, the system isn’t silent, but it’s more than quiet enough to forget it’s running while you’re in the basement once the euphoria of a successful installation wears off. In terms of reliability, it’s about as reliable as the P382LE51, which is as reliable as the P372LE51, which you can expect up to 20 years of problem-free functionality from due to the life-extending properties of the basin and integration of the parts in the enclosure. The part most likely to fail over time is the switch, and as noted earlier, that can be pulled without doing anything significant to the pump or anything whatsoever to the plumbing.

If connecting the P382LE41 to existing plumbing, make sure there aren’t any blockages in your existing pipes, or you might have a messy surprise the first time you run it. Similarly, don’t forget that you’re going to need both a ball valve and a check valve; the check valve will go on your discharge to prevent back flow and the ball valve and a few unions will help you remove the lid in case you need to inspect or service the pump.

Liberty Pumps P382LE41 Simplex Sewage System Pros, Cons, and Value Comparison

In conclusion, if you don’t need quite as much power as what you’d get from the P382LE51 but love the convenience, quick installation, and reliability of the pre-assembled approach, the P382LE41 is an excellent choice for a bit less money. It’s durable, relatively simple to install, and provides no-nonsense functionality for years while not needing constant supervision. Our main recommendation would be to consider the PRG101A if you absolutely can’t afford any downtime or if you will install the sewage pump in an environment where clothing, feminine hygiene products, towels, rags, wipes, or other difficult solids are likely to be flushed down the toilet. If this doesn’t describe your operating environment and you don’t need quite as much head or speed as that offered by the P382LE51, the P382LE41 will work just fine.

Liberty Pumps P382LE51 Pro380 Sewage Pump System Review and P372LE51 Comparison

It doesn’t matter whether you have a single family home, tenants in a property you’re renting out, or employees and customers in a small business setting: if you have a below-grade sewage system (e.g., a toilet in a basement), you’re going to need a sewage pump to pump sewage to a municipal system. Similarly, if you’ve got a septic tank, you already know you’ll need a sewage pump to go along with it. There are lots of cheap options out there, but they tend to fail quickly and not so cheaply. We prefer doing things right and doing things once, which is why we typically recommend either sewage ejector pumps in pre-assembled systems or upgrading directly to sewage grinder pumps.

Do you absolutely need a sewage grinder pump like the Liberty Pumps PRG101A? Not necessarily. If your family, tenants, or employees and customers religiously only flush human waste and toilet paper, you’ll get by just fine with a sewage ejector pump. But to maximize reliability, you’ll want a pre-assembled system like the Liberty Pumps P372LE51 or what we’re reviewing today, the Liberty Pumps P382LE51 Simplex Sewage System. It’s basically the P372LE51 in a shorter and wider basin. Does it work just as well? We think so. You can read our full review below and you can buy it here.

Key Features of the Liberty Pumps P382LE51 Simplex Sewage System (60 Second Summary)

The Liberty Pumps P382LE51 is a pre-assembled residential and light commercial sewage ejector package in a shallow system design. It uses the LE51A sewage ejector pump and is powered by a 1/2 horsepower electric motor with an adjusted maximum pumping rate of 8,400 gallons per hour and 24 feet at maximum head. The pump package includes Liberty Pump’s 3 year warranty and is 24 inches tall, 24-3/8 inches wide at the base, and has a maximum diameter of 27-5/8 inches. It weighs 64 pounds and arrives fully assembled.

Liberty Pumps notes the P382LE51 is specifically designed for installation in bedrock and difficult soil conditions due to requiring less vertical excavation than the Pro370 series (i.e., the P372LE51). It can pass 2 inch solids and runs on 115 volts single phase AC at 12 amps with 22.5 locked rotor amps. Thermal overload protection in the motor occurs at 221F while liquids will be pumped at up to 140F. An automatic mechanical wide angle float switch is included and the pump uses a 2 inch FNPT discharge.

The P382LE51 has a maximum pumping rate of 8,400 GPH at zero feet (slightly slower than the standalone LE51A), which drops to 6,480 GPH at 10 feet, 2,640 GPH by 20 feet, and max head and shut off occur at 24 feet. The primary bonuses of the system include the QuickTree approach, which allows you to reach, pull, and replace the float switch via the top of the basin without disturbing neither the pump nor the plumbing, and the basin itself. The pump itself is anchored within a 41-gallon basin that provides a 40% capacity increase compared to standard 18 inch x 30 inch basins, which leads to a greater lifespan in both the pump and switch by pumping an equivalent amount of sewage with fewer on/off cycles. The system arrives fully assembled and includes a clear plastic top cover for protection during masonry and rough-in electrical work.

How Does the Liberty Pumps P382LE51 Compare to the Liberty Pumps P372LE51 and PRG101A?

Compared to the P372LE51, the P382LE51 is identical in nearly every aspect except in its dimensions. The basin in shorter and wider instead of taller and narrower; it’s 24 inches tall instead of 30 inches and 27-5/8 inches across at its widest point instead of 24-1/2. The basins have the same capacities, but the Pro380 basins are shorter so less digging and a shallower burial is required in difficult soil environments such as clay or bedrock.

Compared to the PRG101A, the P382LE51 is faster, cheaper, and comes with a basin. But because it’s powered by an ejector pump instead of a grinder pump, the P382LE51 won’t be able to handle difficult solids like clothing, feminine hygiene products, sanitary napkins and diaper wipes and other rags, towels, and difficult solids that people shouldn’t flush but might flush anyway. If you’re worried about downtime or pump damage due to the potential of such things being flushed, you need to bypass the P382LE51 and move directly to the PRG101A. It’ll also give you a stronger motor (1 hp vs .5 hp) and more than twice as much head at 50 feet vs 24 feet.

Our Short and Long Term Experiences Installing and Using the Liberty Pumps P382LE51 Sewage Package

Installation is identical to that of the P372LE51; the manual is detailed and easy to follow, and you’ll primarily want to budget about 7 hours for the job if you’re experienced with sewage pump installations.

Regarding longevity, the combination of the LE51A internal pump and the pump and switch-preserving features of the basin should provide you with significantly more working life than the lifespan you’d get from the LE51A independently; it should be possible to get up to 20 years with the system, although user results can and will considerably vary. Your ability to pull the float switch if it goes bad without affecting the pump or plumbing also increases the system’s lifespan and ease of maintenance.

Troubleshooting and Installation Tips to Get Your Liberty Pumps P382LE51 Working Sooner

As with the other sewage pumps in the Pro380 and Pro370 series, your main issues at startup, should any occur, are likely to involve the pump’s not starting, the pump’s not stopping, or its running without pumping sewage.

If the pump isn’t running, you’re probably dealing with one of four things: a power issue, a stuck float switch, not enough liquid to trigger the switch, or a switch that’s gone bad. If the pump won’t stop, you’ve either got a stuck switch or one that’s gone bad. If the pump starts but doesn’t pump water or sewage (because you’ll remember to test it with water before with sewage), you’ll either have something blocked, jammed, or damaged. It might be a locked or closed discharge, a closed or backwards check valve, a closed ball valve or gate valve, a jammed impeller, or a plugged volute casing.

Most of these issues are easy to fix by replacement or physical adjustment. However, if your pump starts but won’t pump, you might also need more head than what your pump can give. The P372LE51 won’t give you extra head; we’d recommend switching to the PRG101A, as it tops out at 50 feet instead of 24. Alternatively, if you’ve got jamming or plugging issues, the grinder in the PRG101A will also be a much better choice than any sump ejector pump-based system.

Liberty Pumps P382LE51 Simplex Sewage System Pros, Cons, and Value Comparison

In conclusion, the P382LE51 is one of the best choices on the market for a sewage ejector pump system. Practically speaking, it does everything the P372LE51 does except in a squatter package, which means less vertical digging and a cheaper installation in an environment with bedrock, clay, or other difficult soil conditions. If you’re looking for the most reliable way to pump sewage in an easily-installable package, either the P382LE51 or P372LE51 will serve you well. Our only recommendation would be to choose the PRG101A or its simplex package if you need grinding capabilities to deal with feminine hygiene products, rags, towels, clothing, or wipes that family members, tenants, employees, or customers may flush down your toilets. Let your risk tolerance, clientèle, and budget be your guide.
