Q: What size battery is required. Does charger shut off when battery is fully charged (does it have overcharge protection)? Where is the main pump suction port? What activates the back up pump? What is the horsepower of the backup pump. If the main pump fails can it be replaced by any pump?
by Darrel F from Illinois on August 16, 2016

A: The recommended battery is the Wayne WSB1275 - Maintenance Free AGM Backup Sump Pump Battery (75 Amps) for the Wayne WSS30V - 1/2 HP Combination Primary and Backup Sump Pump System, however most any 12V, deep cycle, maintenance free AGM battery will work in the 75 amp or 100AH (amp hour) rating. The oversize battery case (included) will accommodate a 12-volt SLA battery (up to a 27-frame size).
Be certain that the area around the batteries is well ventilated. Before servicing the batteries, blow away gasses by waving a piece of cardboard near the batteries.

The control box has a DC charger designed to shorten the recharging time of your battery, and to prevent overcharging. In addition, the control box has
a time delay which keeps the pump from repeated, short cycles when it shuts off. The time delay feature will allow the pump to run 20-25 seconds after the switch reaches the off position.

The main pump suction on this pump is actually just above the base where the line of square holes surround that bottom section of the pump. This is what's known as a top-suction and will help prevent clogging of debris that might normally clog a bottom suction pump.

The backup pump is activated by a separate float switch that is set to activate a few inches higher than the main pump float switch.

Since most backup pumps are operating on DC 12V power, they do not have any HP rating. Rather, they are rated in GPH (gallons per hour). The backup pump in this system can pump a healthy 2300GPH at a 10 foot head which rivals many standard 1/3HP 120V operated primary or main sump pumps.

If the main pump should fail, it is recommended that you replace it with another Wayne CDU800 - 1/2 HP Cast Iron Submersible Sump Pump w/ Vertical Float Switch since all the piping and included check valve is already setup for that pump.
Of course, if you should decide to go with another pump, you could always separate the two pumps at a later date and go with the pump of your preference.

I would also suggest reading the WSS30V INSTALLATION MANUAL for more information on how this system operates and is installed.
If you have any other questions, please let me know.
by Jim, Product Expert
Q: If either pump should ever fail, can they be replaced in the unit? Or does the whole unit needed to be replaced?
by Chris M from New York on January 05, 2016

A: The pumps and components can be replaced HOWEVER, you would need to contact Wayne tech support for replacement of the backup pump or controller. The main pump can be replaced with the Wayne CDU800 - 1/2 HP Cast Iron Submersible Sump Pump w/ Vertical Float Switch.

Q: Jim. I have a 11 inch basin size. I am interested in a combination primary and back up sump system. What do you recommend. Price is not an issue. I am interested in Zoeller, Liberty, or Wayne or whatever you recommend. I dont think I can jackhammer out the basin if I had to, although I would love to.
by Vito Ranieri from Pennsylvania on June 21, 2015

A: Thank you for contacting Sump Pumps Direct.

Here is what I found.

Basement Watchdog

10 Inch minimum basin needed.

Myers Pump

10 Inch minimum basin needed.

Thank you
by Jim, Product Expert
Q: How does the system determines that the primary pump is not keeping up? By water level? running time of the primary?

Also, if the primary fails/breaks does the backup kicks in?

Thanks

by Edgardo from Pennsylvania on May 17, 2014

A: Thank you for your interest in Sump Pumps Direct. Each pump has it's own float switch. The float switch for the battery backup pump is set a few inches higher than the float switch for the main pump. When the main or primary pump is having difficulty keeping up with demand, the water level will rise higher insider your sump basin, thus setting off the secondary or battery backup pump to assist. This process will take place whenever you have AC power available to the system. In the event of a power outage, the battery backup pump, will obviously be your only working pump.
by Jim, Product Expert
Q: Hi, could you tell me what the diameter and depth of the sump basin needs to be for the Wayne WSS30V - 1/2 HP Combination Primary and Backup Sump Pump System?

Thanks.

by Erica from New York on February 26, 2014

A: The Wayne WSS30V requires a minimum basin size of 15"W X 22"D.
by Jim, Product Expert
Q: Which is better, a battery back-up system or a water back-up system?
by Linda L from Kentucky on February 06, 2014

A: Depending on the water table in your area and the potential for flooding you could go either way. If your water removal needs are below average, you could elect to go with a low GPH rated battery backup sump pump or water powered backup. Please note that water powered systems will only work with a minimum of 20-40 PSI. They will not work if you draw your water from a well. The typical water powered system would provide between 300-1000GPH of pumping capacity. If you're in a little higher water table that the flooding potential is a bit higher, you may want to consider a battery backup system rated at between 1000-2300GPH. If the flooding potential and water table are very high, you might look at the systems rated at 2400GPM and higher. You should also check with your local municipality to make sure that they are allowed as some municipalities have outlawed them as they do waste water in a sense.
by Jim, Product Expert
Q: If the 120 v pump can't keep up it sounds as if the battery backup pump will kick in---but the units share a common pipe so how can you add water /flow to an already maxed out pipe?? Would this not just increase head pressure on the battery pump causing it to work even harder????
by Mark F from Wisconsin on April 10, 2013

A: Thank you for visiting Sump Pumps Direct. You bring up a very good and important point, Mark! Most primary (1/4HP - 1/2HP) and battery backup pumps discharge to a 1-1/2" discharge pipe and will be installed separately but due to the discharge system already in place, be piped or "Y'd" together. In MOST cases, the total pumping capacity by both pumps at the same time will be handled by that 1-1/2" discharge pipe and will not cause any extra stress or back-pressure on those pumps. That being said, for optimum performance of both pumps, they should be connected to separate discharge pipes. Again, that is not always possible. In cases of extreme high water tables and frequent possible flooding where high capacity pumps are required, you should definitely run a separate discharge pipe for each pump you have installed.
by Jim, Product Expert
Q: I'm looking to purchase the Wayne WSS30V Combo. The specs say there is a check valve in the unit. Can I still use the Watchdog Klunkless Check Valve as well?
by Tim L from Wisconsin on July 30, 2012

A: Typically, you only want to use a single check valve for each pump so I would recommend just sticking with the check valves that are included with the Wayne system.
by Jim, Product Expert
Q: Is this Wayne WSS30V - 1/2 HP Combination Primary and Backup Sump Pump System an AC/DC system or a DC system?

Also please let me know if I have this straight. An AC/DC system means that the backup pump can be called into use if the main system is overloaded. In a DC system the backup pump only gets called into service if there is a power failure on the first.

by Bryce Brunswig from Nebraska on April 29, 2012

A: The Wayne model WSS30V is a combination primary sump pump and battery backup sump pump. The primary pump will operate on 120 volts and the battery backup pump operates on 12 volts from the battery that is installed along with the system and will operate when there is a loss of power. The battery backup pump will also operate in the event the primary pump cannot handle the incoming water, but will operate using the battery power and NOT 120 volts.

Very Satisfied So Far
The pump was what I was looking for to replacer my existing pump made by a different manufacturer.

The installation directions are flawed, especially in the description of the check valves. The check valves are integrated into the pumps structure and not external as the directions show. This is clearly shown on the pump box.

The website description of the product does not show that a battery box is included with the pump although the battery must be ordered separately.

Easy Install, Might Need A Bit Of Adapting
Pretty much just lift out the old, lift in the new. All set up and much easier than installing separate main and backup pumps. But for me, there was an inexpensive glue-in adapter I had to get at a plumbing supply store to go from the 1 1/2" output to the existing 1 1/'4'' PVC output pipe, along with cutting that existing PVC pipe back a few inches as the Wayne sits higher. The battery costs $100 locally. The unit itself works well, and much quieter than the old unit.
Pros: Quiet, Easy To Use, Price, Easy to install.
Cons: Bad Instructions

Ronald,
I'm sorry to hear of the issues that you experienced with your installation, Ronald. Typically, most combination systems are designed for an easy swap out. Unfortunately, not ALL cases are the same, which may result in more time and/or modifications in the installation. I'm happy to hear that the system is performing well for you and the sound level is within your liking. If you should have any other questions or concerns, please don't hesitate to contact me.

Sincerely,
Jim Owiecki

Great Product. Easy Install.
Product was easy to use and was installed in a little over a half an hour. The instructions are not easy to follow as are not for the combined unit but rather for both the primary and backup separate. However, because the product is substantially put together and check valves are in place, very little is difficult to figure out. It is as close to drop-in ready as possible. We have found the unit is very quite compared to our previous unit, and are hopeful that works for many years to come.
Pros: Quiet, Easy To Use
Cons: Bad Instructions

Really Solid Product
Just installed it. Works very well. The instructions were a little confusing in that they specified how to install a check valve, but the unit comes with check valves. Also, do you need to install a bleeder hole to avoid air lock. A quick phoned call to the Wayne customer service confirmed that no bleeder hole was needed and yes indeed the unit comes with check valves so no need to install more. Overall the unit appears solid and should perform well. We will see. Ask me again in a year
Pros: Quiet, High Quality, I'd Buy It Again, Fast
Cons: The instructions were confusing for the specific make and model.

No Sleepless Nights!
Product came already assembled, I made one cut and inserted a clunkless check valve, (just to insure quietness, might not be necessary in all installs), and in 20 minutes it was ready to go! It can't get any easier! I did buy my own battery, and it works fine. No sleepless nights here! I wished all home plumbing jobs were this easy! Good price, quick ship! Awesome.
Pros: Quiet, Price, I'd Buy It Again, Reliable

Sump Pump Success!
We love our new primary/backup sump pump. During a heavy downpour (over 5 inches of rain) we lost power. Unfortunately our 20+ year old sump pump did not have a battery backup. After bailing water for over 6 hours we decided a new sump pump and battery backup pump system was a necessity. After extensive research we decided on the WSS30V - 1/2 HP Combination Primary and Backup Sump Pump System. My husband had it installed in about 30 minutes. We have since lost power on two separate... more

Works Great - Short Power Cord Very Dissapointing
So far it has worked extremely well. Have not had any power outages so no experience with the backup pump yet.

The primary pump is extremely quiet.

Be aware that the alarm warning that the small pump has kicked on is relatively low volume and runs for a very short time. As far as I can tell there is no adjustment available for volume or duration.

I can't understand why a system that costs this much has such a short power cord. Even the piece of junk pump I replaced had an 8 foot... more

It Is That Good
I just replaced an 11 yr old, noisy but still working sump pump. The old pump would wake us up out of a sound sleep. This new pump installed in about 20 minutes. I tested it with 5 gallons of water and could not hear it run and I thought oh no. But as I looked, the water was gone. The battery backup was just as quiet. I demonstrated the pumps ability to my wife and she said it s not running. I again had to show her how the water had disappeared. No longer do I have to run outside and fire up... more
