The cord between the pump switch and the battery box is 8', so depending on the depth of your sump pit 7' to 8' will be ideal.

Response from Wayne Water SystemsNov 18, 2025
Thank you so much for leaving us a 5-star rating! We truly appreciate your support. If there is anything we can assist with please feel free to reach out. Your feedback helps us continue to improve! Thanks again, and we look forward to welcoming you back soon!
This pump is very easy to install and runs well. However, if you need to change out a pump it becomes a nightmare. To change out a pump, you need pull the entire system. After pulling the system there is threaded PVC coupling that needs to be unscrewed to remove the main or the back up pump. I have purchased 3 of these systems and 2 of the 3 have had cross threaded PVC couplings attaching to the main pump. This makes it next to impossible to get the used pump out and the new pump in. If this is a system that last you 5 years without having to change a pump, it may be worth it. If you have to change your pump out every year, I would highly recommend you stay with a separate back up system. This allows the back up to run while you are changing out your main pump which is not an option with this system.

Peace of Mind in one complete package
I did a lot of research before choosing this system. I selected the Wayne system because the pumps seem to be solidly built and the package appears to be well designed. The installation of the pumps and the setup of the battery backup system was not difficult. I tested both pumps and they both do an effective job of removing the water from my sump. Only issue is that the system is very large and it just barely fit into my sump. So make sure your sump basin is large enough to accommodate it.

Solid. This thing is a tank, most other battery back up pumps (including the one this replaced) are pretty dinky. Too bad it doesn't come with a battery but this way it allows you to pick exactly what you want. I went with a maintenance free style. Not sure if the description states but it also comes with an in line check valve. Also on crock size requirements: I have a tapered standard crock, 22in deep, 18in at the top and 15in at the bottomt and this fits with a little room to spare on the sides.

It took less than 1 hour to install. Only problem was Watchdog battery did not properly fit in the Wayne Case. Should have said you needed a Wayne battery but salesman said any battery would fit. Other than that it works like a charm

Product was shipped directly to house and came a day earlier than expected. Product was easy to install just needed to buy a rubber pipe connector to put the two pvc pipes together then 10 minutes later it was up and running. Product is of excellent quality. The operation of these pumps is way quieter than my old one.

The Wayne WSS30VN - a simple & easy replacement for my 25 y.o. pump with a complete backup system...
The Wayne WSS30VN - a simple & easy replacement for my 25 y.o. pump with a complete backup system.
Although my old pump still worked after 25 years of hard use, it started to regularly trip the GFCI. So I decided to look for a system that combined a main AC sump pump and DC battery-backup pump. After a full day of research, reading reviews and comparing prices, I settled on the Wayne WSS30VN. As a last step in my decision process, I called the company to gauge Wayne's customer service response - I was favorably impressed. The call was answered quickly by Bob (great support person), and we went over a list of questions I had regarding the operation of the float valves, back-up electronics, and some modifications I planned on making to the discharge pipe to the foundation exterior. All my questions were satisfactorily and completely answered, and Bob made sure I was fully comfortable with all phases of the installation process. I ordered the unit from Home Depot, and the pump arrived by FedEx only two days after I placed the order.
The system is as rugged and compact as it appears in the pictures, and, for the most part, really was a "plug-and-play" "drop-in" replacement. (Note that this assembly requires a sump basin with at least a 15" diameter at the base.) Because the main pump (AC power) float switch is not shrouded, when placing the unit in the sump basin, care must be taken to ensure that the float is at least an inch from the side of the basin so it can operate freely. Also, the float must not be directly under the flow of water from any of the water inlets. After slowly rotating the system within the basin, I found an acceptable position, but it was clear I would need to slightly alter the position of the existing discharge pipe to accommodate the location of the factory plumbing. I took that need as an opportunity to add, modify and reorganize several other components (something I had been "meaning to do" for years.)
Although each of the two pumps came from the factory with check valves, I decided to add a "klunkless" check valve (HD 541996) and quarter-turn ball valve (HD 784923) above the pump. To add vibration isolation and wiggle-room for pump torque, I connected the lateral PVC pipe through with a 1½" flexible rubber 90 ̊ coupling. I also added a 1½" PVC slip union (HD 242935) to make it easier to remove the pump from the basin for maintenance.
Once that was done, I poured several gallons of water into the basin and plugged the main pump into the GFCI outlet - it worked perfectly - and almost silently. Within seconds the water was pumped out and the unit shut itself off. I then installed the backup battery (separate purchase). The one I chose had the highest amperage rating I could find in a maintenance-free, Sealed Lead Acid (SLA), Absorbent Glass Mat (AGM) battery that would fit within the battery case provided with the Wayne system (group 27-frame size) - the Powersonic PS-121000U 12 Volt, 100 AH. After making sure that the battery was fully charged, I unplugged the main pump and battery charger (which sounded a brief audible alarm), and filled the basin. As soon as the water level rose a little over the DC pump's float switch, the backup pump fired up (again, with a brief alarm) and emptied the basin almost as quickly as the main pump had.
Because the position of the outlet pipe had to change, and in order to permit the basin cover to be put in place (which it hadn't been for years), I decided to also reorient 4 discharge pipes that emptied into the sump basin (2 AC condensate drains, and the hot water heater drip pan and pressure relief valve outlet). As a final precaution, I also added a water bug water sensor to my house alarm system and placed it on the floor adjacent to the sump basin. Project done!
So far. my choice of the Wayne WSS30VN has proven to be an excellent decision. As of December 15th 2018, the Northern Virginia area had experienced the highest rainfall totals ever recorded, beating the 1889 total of 61.33 inches. In the last few weeks of 2018, this system has been put to the test, with the pump cycling 1-2 times a minute for days on end. It is easily up to the task!
The only "Cons" I can offer are minor:
- The battery charger wall-wart should come with a longer cable. Since it is recommended that this charger NOT be plugged into the same GFCI outlet as the main pump, in my opinion the charger cable should be at least 10-12 feet long. Currently I have temporarily plugged the charger into an extension cord, but plan to have another outlet installed soon (off the one in the picture that faces another room).
- Also, this charger is fairly heavy to have hanging simply by the friction of the AC prongs. It could use a bracket, maybe one that uses the center screw in the duplex outlet cover.

The pumps come pre-assembled which is a time saver. Added a short piece of 1.5” PVC pipe so the check valve would be above the sump pump cover. Installation was quick, cleaned bottom of pit and put a concrete stepping paver in it for the pump to set on. I wanted to purchase the Wayne Maintenance Free battery they recommend but decided to purchase the watchdog battery (BW-27AGM) instead.
The battery box has the controller built into it. The main pump work great and is quiet, I unplugged the main pump to simulate a power failure. Poured a couple of buckets of water into the pit until the back up pump kicked on. It pumped all the water out pretty quick and quietly, I would recommend.

This is a very rugged, well made system. I've installed these types of back up pumps before with other brands but this one seems to be of much better quality. It does not come with a battery, even though the box states that it is a complete system. It also requires a minimum 15 inch wide sump pit because the two pumps are side by side and not piggy backed. A lot of older pits are only 12" wide, so measure before you buy. Another nice feature is that the GPH pump rate of the battery back up is almost as powerful as the main pump.
