Problems You Might Face With Wayne ESP25

This ESP25 from Wayne has earned the satisfaction of it’s customers. Customers have found it surprisingly fast and quiet.

Still, people face some issues and we would like you to know them as well.

Bad Float Switch Design

A common issue with every sump pump is the automatic switch. It is designed to float as the water rises and to give a signal to the pump. But many times the switch gets stuck and fails to identify the water level.

You can solve this problem by installing a water alarm just above the backup’s built-in alarm. When the float switch fails to give a signal and start the pump, the water level would increase. As it touches the water alarm, you will be notified by the ringing. The purpose of this alarm is to let you know that your backup has failed. Then you can take action.

You Have To Include Battery

It is a 12V battery backup sump pump. It works on DC-power. To start it, you require a 75 AH marine deep cycle Lead-acid battery. But unfortunately, the battery is not included in the package. You have to pay for it.

That’s why most people don’t buy it. They think it is not necessary. And even if they buy it once, they don’t think of replacing it again.

Batteries have a limited life cycle. It can be 6 months or a year. After it, the fluid in the battery cell dries out and it expires. The pump won’t even start without a battery. No battery means you get zero support during emergencies.

You can solve this problem by examining the battery from time to time. If you find it dead, replace it. Yeah, it sounds costly. But in actual sense, this is more like a necessity than a luxury.

Wayne ESP25 Review: Features And Benefits

Now let’s dig deeper into our Wayne esp25 backup system review. Down below we have simplified all the amazing features and benefits.

Thermoplastic Construction

The use of thermoplastic as the housing material for sump pumps is rapidly growing. Thermoplastic doesn’t have much heat conductivity. That’s why it can stay in shape at a higher temperature too. The working temperature of this pump is 33 to 120 degrees Fahrenheit.

And that’s just one benefit. Thermoplastic is resistant to corrosion and rust (all plastics are). We know how much harm corrosion can cause.

It shows less wear and tears over time. Also, Thermoplastic is good at handling toxic chemicals. That’s why this pump is fit to survive a challenging environment better than its metal counterparts.

Automatic Vertical Float Switch

It has a separate float switch to trigger the pump. You won’t have to worry about the circuitry between both of the pumps (primary and ESP25). The triggering level is set higher in this backup pump. Now it only signals danger when the former pump has failed due to a power cut.

The best thing about the ESP25 is that it also works as a helping hand when the AC-powered pump becomes inefficient. When the primary pump becomes insufficient to handle the water inflow, the water keeps rising. On its way, it touches the reed float switch of the backup pump. The switch then triggers the pump to start pumping.

In this way, the ESP25 comes forward and takes action to protect your house during a tough time.

12V Battery Powered Performance

This 12-volt battery-powered motor is equivalent to 1/3HP motor. It is the right choice for an average household. It can lift 3300 GPH @0 head, 2300 GPH @10 feet, and 1500 GPH @15 feet. This flow rate is better than any average primary sump pump.

There is a specific requirement for the battery. You can’t use a 105AH battery or larger than a group-27 battery. The battery box along with the charger is fixed for 75AH deep cycle lead-acid battery.

The battery box is made of Polyethylene. It provides benefits like impact-resistance, corrosion-resistance, easy maintenance, etc.

Additional Features And Benefits

  • It comes with an LED indicator. It lets you know the charging status of this pump and whether it is running or not.
  • It also features a nice alarm. You can hear it from one floor above. It is a signal that the backup system has started working.
  • It includes an advanced charging system. It means you can charge it faster.
