It has a reliable pumping capacity that can meet every user’s demands wisely. The worry-free confidence that it provides is the unique reason for liking this product. Moreover, featuring a 15-inch discharge outlet, is just perfect for every user.

  • Efficiency

Efficiency is the thing I have seen most evident in this battery backup system. It is responsible for reducing heat in the DC motor with stable motor housing while increasing its life. It’s motor and cylindrical design also leaves a significant impact on the pumping performance. You will understand the need for an independent backup sump pump system when you will clean up a flooded basement.

Wayne is something that will bring peace of mind during such power outages while providing confidence to the user that two pumps can help you cope up with such unusual events. Aren’t you impressed with its efficiency? Well, I am, and soon after reading the whole review, you will be too.

  • Battery power requirements

Generally, Wayne has an excellent battery operating system. On that note, it requires one deep cycle battery to operate, thus known as a 12V backup pump. You can use a 40Ah battery or a 75Ah deep-cycle for significant results.

Putting an eye on the latter capacity, the pump can keep the basement dry for at least three days. Isn’t it much reliable? You can enjoy three days without worrying about a flooded basement. There is an audible alarm to ensure that the pump operates while informing that the primary pump usually fails.

Wayne recommends using an SLA battery, but a lead-acid battery will do the same work. Now let us also talk about some tips to take care of the storm. Every six to twelve months, take a look at the battery’s condition, whether it needs a change or not. Keep in mind this battery backup system will use only one battery.

  • Versatility

Versatility is prevalent in the Wayne backup sump pump system. It is a sump pump running on a 12VDC power source. Haven’t you seen its polyethylene case? Well, it makes the system worth buying. This battery case can hold up to any group 27 size batteries effectively. Sometimes they are being used in conjunction with Wayne’s AC-powered pump for more efficient working. It is a backup for pumps of any manufacturer and any size.

Instead of these versatile features, it completely stands alone. You don’t need any circuitry between ESP25 and your existing pump, and it constitutes a different float switch for operating with ease. You just need to install this system along with the existing pump for working. Another noteworthy thing to consider is that the Wayne system also acts as a boost pump for assisting your primary pump while discharging at the same or dedicated outlet line.

Frequently Asked Questions

  • For how much longer does a battery backup lasts for a sump pump?

Wayne ESP25 battery usually depends on how much severe water problems you are facing. See if the battery projects last for almost 53 hours and are pumping at a reliable rate of 2700 GPH once every five minutes. It is something projected. But if you have some serious problems, the same pump might run once a minute, and the battery lasts up to 12 hours.

  • Why does my battery sump pump sometimes keep beeping?

Is your battery sump pump keeps beeping? It is because the pump is not working, and there are two significant reasons for this non-working. The first can be that the pump is not receiving enough power for its correct operation.

Secondly, your pump might have been worn out or old. In this case, you have to replace it. The alarm will also go off whenever it senses water. Rarely there can be any plumbing leak that is responsible for triggering the alarm.
