Liberty Pumps 287 1/2 HP 280-Series Sump Pump Review: Fast, Reliable, Compact, and a VFM Switch for $200

When it comes to sump pumps, we’ve reviewed enough to agree with the maxim that you generally get what you pay for. For example, a Zoeller M267 isn’t cheap, but it’ll give you faster water removal and longer service than virtually any other AC pump on the market. However, there’s a bit more to think about if you’re on a tighter budget. What’s going to power your sump pump? How reliable does it need to be? And of course, how much can you spend?

If you’re looking for a reliable sump pump, the first decision you’ll need to make will be whether to go with an AC-powered or water-powered pump. If you want a water-powered pump due to living in an area with frequent power outages, the best on the market is the Basepump CB1500.  If you want a an AC-powered pump, there’s nothing faster or more reliable than the Zoeller M267. However, if you’re on a smaller budget, such as around the $200 mark, you’ll probably be looking more at pumps along the line of the Zoeller M63, Zoeller M57, or Wayne CDU1000. Today we’ll take a look at another $200-class backup sump pump that potentially offers decades of value: the Liberty Pumps 287 Automatic Submersible Sump Pump with VMF Switch. It’s not the fastest AC-powered pump in its price range, but it’s probably going to be the most reliable, which counts for something. We think it’s a great deal; read on for details, and you can buy it here.

Key Features of the Liberty Pumps 287 Sump Pump (60 Second Summary)

The Liberty Pumps 287 sump pump is an automatic submersible sump and effluent pump. It’s driven by a 1/2 horsepower thermally protected electric motor and can pump up to 4,020 gallons per hour; it comes with a 3 year warranty. It is 10 inches in diameter and 14 inches tall; it is housed in cast iron and weighs 19.5 pounds on our scale.

No battery backup is included with the Liberty Pumps 287. It is capable of handling up to 3/4″ solids and can handle liquids at up to 140F. The thermal overload temperature of the motor is 221F. The motor runs on 115 volts and 8 amps at full load. It includes a quick-connect 10 foot power cord. The float switch is a vertical magnetic float (VMF); it is non-adjustable and turns on at 9-1/2 inches and shuts off at 4 inches. The discharge is a 1-1/2 inch NPT and the sump pump is rated for installations in sump pits down to 10 inches in diameter.

Water removal peaks at 4,020 GPH at 0 feet, dropping to 3,360 GPH at 10 feet, 2,520 GPH at 20 feet, 1,350 GPH at 30 feet, and with shut-off and max-head occurring at 37 feet.

How Does the Liberty Pumps 287 Compare to the Zoeller M98, Zoeller M63, and Wayne CDU1000 Sump Pumps?

Perhaps the most unique element of the Liberty Pumps 287 is the magnetically-operated vertical float VMF switch. Unlike the typical mechanical float switch found in Zoeller and Wayne designs (e.g., a switch set into motion by a float, rod, and arm assembly), the Liberty 2xx series typically makes use of a magnetic/reed switch set into motion through a motor rod and float assembly. In plain English, this means the magnetic/reed design is less prone to failure than the mechanical design since the reed switch in the switch housing doesn’t need a rubber gasket installed to keep the switch arm sealed. Getting rid of the need for the rubber seal means the switch can’t fail due to water intrusion or this particular kind of mechanical failure. To put it more simply, there’s a good chance you’ll get at least as much life–if not more–out of this Liberty Pump as you would from any Zoeller or Wayne sump pump.

Aside from the difference in float switch design, the Liberty Pumps 287 is simply faster than most pumps on the market while offering a greater maximum pumping height than almost any other sump pump available. The Zoeller M57 tops out at 2,580 GPH and shuts off at 19 feet. The Zoeller M63 increases the shut-off height to 20 feet but is no faster than the M57. The Zoeller M98 tops out at 4,320 GPH and shuts off at 23 feet, but has reliability issues. The Wayne CDU1000  tops out at 5,400 GPH but shuts off at 22 feet. Even the mighty Zoeller M267, which can pump up to 7,680 gallons per hour, shuts off at 21 feet. If you need to move water a great distance vertically, the only pumps we’ve found under $500 capable of moving water higher are the Tsurumi LSC, which shuts off at 40 feet, and the Liberty Pumps 297, which shuts off at 48 feet. However, unlike the Liberty Pumps 287 or 297, the Tsurumi isn’t automatic.

Installation is straightforward; you essentially drop the pump in the pit, connect it to the discharge pipe, set the float, and plug it in. The main thing to remember is that you don’t want to let the pump run dry; even though a thermal overload is included to protect the motor, it’s not something you want to test any more than necessary.

Once installed, you can expect more than a decade of trouble-free use from the 287 as long as you remember to check the float switch from time to time. That said, it’s always a good idea to have a backup pump set up whenever you’re depending on a sump pump to protect something you value (e.g., a dry basement). In day to day operation, it’s a very quiet sump pump and a rather attractive one. We’re also happy to note it’s capable of grinding solids in the pit, making it a good choice for locations with contaminants in groundwater.

Troubleshooting and Installation Tips to Get Your Liberty Pumps 287 Working Sooner

No matter how reliable an AC sump pump may be (and the Liberty Pumps 287 is one of the best), we’d never recommend having just one sump pump installed in a home; redundancy is key. It doesn’t matter whether you choose a water-based backup pump like the Liberty Pumps SJ10 or a DC backup like the Wayne WSM3300 (or a budget backup like the Wayne ESP25), you’ll want something to help you if you suffer a power outage during a flood or thunderstorm.

Of course, whatever you get, make sure you install the float switch on the backup above that of the 287 so the 287 activates first while the backup only activates if the 287 doesn’t (or can’t keep up with the water rise). And as with any main sump pump, we also recommend installing a water alarm alongside it. This should be installed above your backup float switch (if you have one) in order to alert you if every water-draining recourse is failing to keep up with rising waters. We recommend the Basement Watchdog. If you’ve got a main pump, a backup pump, and a water alarm, you should have very low odds of ever needing to deal with a basement that floods when it rains.

Liberty Pumps 287 Sump Pump Pros, Cons, and Value Comparison

In conclusion, the Liberty Pumps 287 is quite possibly the best combination of speed, reliability, and portability you’re going to find in an AC-powered sump pump at the $200 mark. If you’re looking for a compact, cast-iron sump pump with an incredible max height that pumps at a good speed while offering superior reliability without costing as much as a mortgage payment, you’ll be hard pressed to find anything better than the Liberty Pumps 287. It’s not the fastest pump on the market, but with the advantages it offers, it certainly doesn’t need to be, and it’s more than fast enough to meet most homeowners’ and landlords’ needs.

Basepump HB1000-AVB Water Powered Backup Sump Pump Review: High Speed Back Flow Prevention for $300

One of the most important parts of a dry basement is a good sump pump. We’ve reviewed dozens of them over the years, and have come to prefer certain models for certain tasks. The best AC pump? We think it’s the Zoeller M267. The top AC/DC combination model? The Wayne WSSM40V. The best backup that runs on batteries? You’re looking for the Wayne WSM3300. But what if you want a.) a water-based sump pump and b.) want a high level of back flow protection?

If you’re simply looking for the fastest water-powered sump, we give the award to the Basepump CB1500. However, if you need something that’s both fast and highly protected from back flow (whether in order to comply with municipal regulations or simply for water safety), you’ll want to look at the Basepump HB1000-AVB Water Powered Backup Sump Pump with Back Flow Prevention Vacuum Breaker. It’s basically a faster version of the RB 750-AVB; both include built-in atmospheric vacuum breakers to keep back flow of sump water out of your potable water line. Some municipalities require it (e.g., many in Indiana, Minnesota, Ohio, and Wisconsin), and even if it’s not required, it’s an additional layer of security you might wish to consider. Our full review is below, but if you’re wondering whether it’s a worthwhile investment, we think so, and you can buy it here.

Key Features of the Basepump HB1000-AVB (60 Second Summary)

The Basepump HB1000-AVB is a water-powered backup sump pump that includes a built-in atmospheric vacuum breaker, or AVB, to prevent back flow of sump water into drinking water lines. As the pump is water based, it doesn’t require electricity, but does require water pressure from a city water system. It can remove up to 1,400 gallons of water per hour (1,400 GPH) and comes with a 5 year limited Basepump warranty. Weighing 10 pounds, it’s 16 inches long, 12 inches tall, and 8 inches wide.

The HB1000-AVB features a 3/4 water intake that can be scaled up to 1 inch but not down to 1/2 inch, as this would not allow enough water pressure from a city line. The sump intake is 1 inch with a 1-1/2 inch discharge. Water pressure requirements range between 40 PSI and 90 PSI with two gallons of sump water removed for every city gallon pumped.

Pumping rates will vary depending on pumping height and water inlet pressure. At 40 PSI, the GPH is 950; this rises to 1,000 GPH at 60 PSI, 1,200 GPH at 80 PSI, and 1,400 PSI at 90 PSI.  The max head is around 15 feet, although your limit will vary depending on water pressure and piping configurations.

As with the HB1000 and PRO variation, the HB1000-AVB features a 9 volt powered high water alarm that sounds at 85 dB.

How Does the Basepump HB1000-AVB Compare to the HB1000-PRO and HB1000?

The primary difference between the HB1000-AVB, the HB1000-PRO, and the HB1000 is the presence of the atmospheric vacuum breaker, or AVB, with the HB1000-AVB. If you buy the HB1000-PRO, you get the advantage of having virtually everything you need for a complete installation included out of the box. However, you can of course buy the necessary accessories separately. But what exactly makes the AVB worth purchasing?

An AVB is a firewall for your drinking water. It keeps sump water from entering your drinking water line if back flow occurs during a pumping cycle. Without one, if pressure drops from your water line while it’s flushing water through the sump pump, it can create a vacuum that siphons sump water upstream and back into your municipal water line. The AVB valve acts to interrupt this by opening up, destroying the vacuum, and killing the siphon. Thanks to an AVB, contaminated sump water can’t enter the water your family drinks. Each Basepump water pump includes a check valve already that’s designed to prevent this,  but this is an additional security check that both homeowners may appreciate and municipalities may require.

Our Short and Long Term Experiences Installing and Using the Basepump HB1000-AVB

It doesn’t take more than around 3 to 4 hours to install the HB1000-AVB as long as you have some plumbing experience or know someone who does. If you need additional time, it will be due to the need to run an additional discharge line from the pump out of your home, since you can’t simply patch into the line for your primary sump pump. While this does add to the installation process, it does give you a fully redundant sump pump compared to the main system, which means you’re not going to find yourself with a flooded basement simply because your main line became clogged or damaged in the middle of a flash flood.

As with other water pumps, the key to longevity is to remember not to exceed the water pressure limit at the intake. Make sure your city isn’t delivering more than 90 PSI to your home and you’re more or less set with sump pump maintenance for the life of the pump.

Troubleshooting and Installation Tips to Get Your Basepump HB1000-AVB Working Sooner

Make sure you have enough water volume to drive the HB1000-AVB; Basepump recommends the bucket test. If you can fill up a 5 gallon bucket to within 2 inches of the brim (i.e., 5 gallons’ worth of water) from an outdoor spigot in under 30 seconds, you’ll have enough water flow to make the HB1000-AVB work in your basement. If it takes more than 30 seconds but under 40, you’ll want to pass on the HB1000-AVB and get the RB 750-AVB. If it takes longer than 40 seconds, neither is likely to work, and you’d be better off with a DC-based sump pump–of these, the Wayne WSM3300 is our favorite.

Basepump HB1000-AVB Pros, Cons, and Value Comparison

When installing the HB1000-AVB, make sure you install the AVB valve at least 6 inches higher than wherever you’re planning on discharging water. This safety is built into the pump, but if you don’t ensure that the water discharge is either level to the discharge outlet or sloping downward from it, water won’t drain out of the pump when the pump turns itself off. And if the water doesn’t drain out naturally, whatever water is left over after shut off will end up in your basement after flowing out of the open AVB valve, since the valve can and does open under pressure.

If back flow prevention is a priority, there isn’t a better option on the market right now than the HB1000-AVB in our books. It pumps a very good amount of water for a water-based sump pump, installs relatively quickly and without the need for unnecessarily complex routings, and it’s also available for a competitive price relative to the non-AVB versions of the HB1000. At this level, it’s hard to see how it could be improved except through making it faster or by including additional accessories to make it easier to install out of the box like the HB1000-PRO. Overall, we’re very satisfied and readily recommend it to anyone interested in no-nonsense back flow prevention and a greater pumping rate than that available in the RB 750-AVB.
