Product Questions Answered by Jim, the Sump Pump Expert
What impacts the lifespan of the pump?
from Wisconsin 
July 22, 2023
What is the minimum size basin that is needed for this pump? What are the dimensions of both pumps combined?
from Michigan 
October 16, 2018
Is it possible to get a 3/4 horsepower sump pump and a combination battery backup pump?
from Illinois 
April 18, 2018
Hi Jim. If I'm out of town and we have two storms a day apart, will the battery automatically recharge to be ready for the 2nd storm? Meaning I don't have to be present to manually intervene?
Lou P.

Is there a notification when the battery or pump fail, or the battery doesn't have enough of a charge?
from Wisconsin 
March 21, 2017
What are the dimensions of the battery box?
Mike H. 
from Ohio 
March 08, 2017
Does the backup pump require a weep hole? Also, will this unit cycles frequently in bad weather, and should I install a rubber boot?
Howard O. 
from Indiana

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?
Darrel F

If either pump should ever fail, can they be replaced in the unit? Or does the whole unit needed to be replaced?

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.

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
from Pennsylvania 
May 17, 2014
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.
from New York 
February 26, 2014
Which is better, a battery back-up system or a water back-up system?
Linda L 
from Kentucky 
February 06, 2014
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????

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?
Tim L 
from Wisconsin 
July 30, 2012
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.
