## Description

Wayne 1/2 hp primary sump and battery back-up pump system comes completely pre-assembled for quick and easy installation. Top suction primary sump pump design minimizes clogging and eliminates the need for a vent or weep hole in the installation. This heavy duty combination system requires a 40 amp hour or 75 amp hour deep cycle battery, for continuous operation when the power is out. Protect your home.

Review: Water pumping when you need it, if it will fit! - Our basement must have been built in the path of an underground stream. After a big rain, water will continue to come into the sump for several days after the end of the rain. Basement flooding is a certainty if the sump pump isn't working. So AC power, or no AC power the sump pump must continue to run! The AC-powered pump component is typical of good quality flooded pumps, powerful and quiet. But it is the DC-powered backup pump that sets this unit apart. We've had other DC-powered backup pumps, but they typically fell short. We have about a 7-foot lift between the top of the sump and the ground surface where the water is discharged. The other backup pumps would run, but strain to remove the water. Not so this pump. The backup pump design is very similar to the primary AC-powered pump and takes only about 30 seconds to empty an 18" round 30" deep sump against that 7-foot (minimum) head. In a recent test following a 4" rainfall event, the backup pump was needing to empty the sump about every 3 minutes during the peak drainage. It ran on battery power (admittedly off a 100-amp-hour AGM battery) all day and through the night without any visible drop in the battery voltage until there was no more water to be pumped. With one caveat, installation is easy, primarily because the plumbing interconnecting the two pump units is built-in. The caveat is that the base of the unit is massive, with the two pumps mounted side-by-side (instead of vertically as many of the lighter-duty units are). We have an 18" circular sump and it just barely fit - in part because while 18" was ample for the center of the unit, the corners just barely fit. We did make one alteration. We are charging our battery using a high quality, stand-alone charger. Why? The main limitation on battery life is likely to be how it is charged (or, if things don't go right, overcharged). The built-in charger may be OK, but given the cost of the battery, we thought investment in a computerized low-amperage charger was a reasonable one. The good news is that the pump control electronics built into the battery box work fine with the AC charger cable detached. The charger type makes no difference when the backup sump pump is actually running, because, by definition, the AC power will be off at that point anyway. Given its solid design and construction, and that it seems to do the needed pumping with little evidence of effort, I'm expecting this unit to keep us dry for many years .
Review: Very quiet and powerful, easy to install. - I have installed several primary and backup sump pumps over the years in different homes and decided I would give this one a try when we built our new home this year. The pump the builder provided was just a primary pump and was noisy. This Wayne pump is the quietest I have ever heard. I paired this with a quiet check valve and all you can hear is the faint sound of water flowing through the pipes. The battery backup pump is actually slightly louder than the primary pump but its still quiet. One thing you need to be aware of is that the backup pump when activated runs for a pre-set time which I believe is like 20 seconds. This is a long time for a sump pump. I would guess they do this to help maximize battery efficiency. In any case you need to make sure you have the float on the backup pump set much higher than the primary pump which means moving the float all the way up onto the exit pipe above the pumps. Once you do that it will be fine. If you do not do that you will be sucking air into your pump which is not good. This instillation was simple just as the product information says. Be careful with some of the older reviews as I think the pump has been upgraded and changed slightly over time. I’ve had the pump installed for about 2 weeks now and we have had quite a bit of rain this week and the pump has done well. I also turned off the electricity and tested the backup pump and it worked perfectly. I purchased the Wayne battery they recommend for use with this pump. This pump is a great option instead of the traditional primary and backup pumps installed separately.

## Questions & Answers

**Q: Is it ok to connect to the primary pumps PVC before the check valve, eliminating the need for 2 check valves?**
A: No, you need a check valve for each pump. This happened to my sump pump installation: Over time, the flapper (acts like the valve) in the check valve deformed a little, detached from its hinge point(s), and ended up in the FRONT part of the body. This meant that when water was being pumped out of the sump, the water forced the flapper into the check valve opening... BLOCKING the flow! The check valve ended up working backwards, basically. With the water unable to flow, after enough time, the sump pump burned itself out. If two pumps are feeding through just one check valve, the same thing could happen to both pumps. Each pump needs its own check valve. It's OK for the discharge lines to merge afterwards. BTW: If you really depend of a reliable sump pump installation, spend the extra $30-$50 bucks and get a couple of industrial-strength check valves (regardless if you have a single or double-pump system). They will be "out of sight and out of mind" parts of your installation; you need to KNOW that they'll last!

**Q: What size pvc pipe goes into the single fitting at the top of the unit,and what method are you using to attach it? Thanks**
A: I glued a three-foot section of 1-1/2" PVD pipe to the wye-fitting at the top of the pump assemble. At the top of the three-foot section I used an 1-1/2" Fernco rubber coupler with stainless steel clamps to connect it to the drain line. You're going to love this pump. It's the quietest pump I've ever heard.

**Q: Can anyone please recommend a battery to purchase for this unit?**
A: I installed a VMAX 127 deep cell battery.  It provides between 36-48 hours of pumping capacity.  Cost ~$300.  I recommend you don't go cheap on the battery.

**Q: does this pump come with a battery**
A: The pump does not come with a battery.

### ⭐⭐⭐⭐⭐ Suburban sub 40 year old Father/DIYer
*by J***M on April 19, 2026*

I bought and installed this 3 years ago. I’ve had no issues this entire time. Installation was so easy because everything is pre-assembled and easy for you to prepare the fittings prior to install. We are on low ground between our neighbors so we get a ton of water entry into our pit every spring (including right this second). This thing has worked hard and performed wonderfully. I have the Wayne battery and check valve as well and I’ve had no issues with either. The check valve is my only concern since it has a ton of failure points and has plastic components and relies upon rubber couplings. I did have a TINY bit of water finding its way out of the check valve but that’s because I needed to tighten the nuts against the rubber gasket. Fixed the tiny issue in 30 seconds. I do exercise the backup pump every once in a while so it doesn’t seize. All in all, a fantastic product.
