Wayne ESP25 Review: Installation and Maintenance

The Wayne ESP25 Battery Sump Pump is easy to install and maintain. Its plug-and-play design allows you to install it yourself without needing a professional plumber. 

It comes with a pre-assembled pump ready to install right out of the box, and it also includes a detailed user manual that walks you through the installation process step-by-step.

Regarding maintenance, I found it easy to maintain. You’ll need to check the battery regularly to ensure it’s charged and replace it every 3-5 years, depending on its condition. 

You may also need to clean or replace the pump’s parts occasionally, but this is a relatively simple process that you can do with essential tools.

Wayne ESP25 Review: Troubleshooting Tips

Many homeowners opt for the ESP25 as a backup sump pump because of its simple installation and maintenance. However, it still requires regular maintenance and upkeep.

Choose a 40 amp battery

It is important to remember that for the backup pump to function correctly, it requires a 12-volt deep-cycle battery connection. Without this connection, the backup pump will not work during a power outage when the AC pump is not functional. 

I suggest choosing a 40 or 75-amp capacity battery, as larger batteries may not fit in the designated battery box. The recommended battery size is 27-frame.

Use a silent check valve

My suggestion for the ESP25 is to opt for a silent check valve instead of a regular one. This will effectively eliminate the familiar noise of “thunk!” or “clunk!” often heard with the traditional hammer check valves when the sump pump shuts down.

Test your pump regularly

Develop a routine of testing your ESP25 every month. Since this is a secondary mechanical tool installed in a basement and often overlooked, it’s essential to conduct regular checks to ensure it functions properly. This will prevent surprises during usage, such as a malfunctioning sump pump.

Install a separate water alarm

I suggest getting a basic water alarm like the Basement Watchdog and installing it in your sump pit higher than the backup float switch. This way, if the water level rises, the main float switch activates the AC sump pump, and if there is a power outage, the backup float switch triggers the DC pump to start. 

If the DC pump fails to work or cannot keep up with the water, the water will reach the alarm sensor, indicating that you must go to the basement. 

Wayne ESP25 Review: Noise Level

In terms of decibels, the Wayne ESP25 Battery Sump Pump produces a noise level of around 70-80 dB, equivalent to the sound of a vacuum cleaner or a busy street. 

Wayne ESP25 comes with a noise-reducing cover that helps to dampen any sound produced during operation. This cover is designed to fit snugly over the pump and is made of durable, long-lasting, high-quality materials.

Wayne ESP25 Review: Pros and Cons 

Wayne ESP25 comes highly recommended. Here are some of the pros and cons of this Battery-Powered Sump Pump:

Despite the drawbacks, Wayne ESP25 Battery Sump Pump is a solid choice for homeowners who want a reliable backup sump pump to keep their basements dry during power outages and heavy rainfall.

It’s crucial to remember that even while the initial cost of this pump may seem excessive, it can ultimately save you hundreds of dollars in potential water damage to your property.

When comparing prices, it’s also essential to consider the additional installation costs and necessary accessories or features. Some suppliers may offer package deals that include installation or other equipment, so it’s vital to research and compare prices from multiple sources before purchasing.

Wayne ESP25 Review: Customer Reviews

The Wayne ESP25 has received mostly positive reviews from customers and experts alike. Many customers have praised the pump for its powerful performance and reliable battery backup. Some customers have also noted that the pump is easy to install and maintain.

However, there have been a few complaints about the pump’s noise level, with some customers noting that it can be quite loud during operation. There have also been reports of the battery failing after only a few months of use.

Wayne ESP25 Review: How Does ESP25 Compare To WSS30V?

When comparing the ESP25 and the WSS30V, it is essential to note that the ESP25 does not come with the CDU800, which is powered by AC. The WSS30V is more versatile as it combines the CDU800 and ESP25 pumps into one device. 

The ESP25 cannot be used as a standalone unit because it requires an already-installed AC sump pump. This is because the battery power of the ESP25 would deplete if used continuously. 

If an AC-powered sump pump is unavailable, I recommend purchasing a separate one or a combined AC-DC unit, such as the Wayne CDU980E or the Wayne WSS30V. These are the best options under $200 and $400, respectively.

Is the Wayne ESP25 Worth the Investment?

So, is the Wayne ESP25 Battery Sump Pump worth the investment

Yes, it is. The Wayne ESP25 is a top-performing sump pump packed with features that make it a reliable and efficient choice for homeowners looking to protect their basements from water damage. 

Its battery backup system ensures that it will continue to pump water even during power outages, and its high pumping capacity makes it suitable for most residential basements.

While the Wayne ESP25 is relatively expensive compared to other sump pumps on the market, its high-quality construction and reliability make it a wise investment for homeowners looking to protect their homes. 

The investment in a sump pump is minimal compared to the potential cost of water damage repairs, so it’s smart to invest in a high-quality sump pump like the Wayne ESP25.
