Product Questions Answered by Jim, the Sump Pump Expert
My water softener wash tube discharges into my sump pit. Will the Storm Pro BA Series Pump hold up to the salt water in the pit?

Hi Jim I have a handful of questions about your StormPro BA-50M. 1. How adjustable is the float switch? I get that I can mount it on the discharge hose and make the pump turn on at any height I choose. But can I, for example, set the pump to turm on at 25" and turn off at 3"? Or do I have a limited range of play between the on/off settings? 2. Is the manual override switch physically located on the pump casing or is there an option for remote control via a cord? 3. Is the outlet port 2" FNPT? 4. Is the float switch mercury free? 5. Is there any way I can get my hands on the user manual prio to purchasing this pump? (PDF download or similar?) 6. And... do you sell to Fed. Gov Agencies? If yes, do you have a special department or person that I need to contact? Thanks! Have a great day!

Hi Jim! I own a couple 1/2's and a 1/3 hp storm pros. I just saw that they are not "Oil Free" pumps, does that mean they need any oil maintenance, why would they mention it otherwise? Didn't see any oil notes elsewhere. Thank you!

Can the StormPro 1/2 HP Cast Iron Stainless Steel Sump Pump be used with back-up battery or it must be plug in to an electrical outlet.

I would like to know how many watts a 1/3 or 1/2 hp sump pump has, because i was think of buying a portable generator in case the power goes off.

I understand that the BA-33M has a switch differential of 6-1/2 inches. Can I modify it with a longer rod to increase that differential and thus further cycling?

I would like to buy the storm pro 1/3 hp pump but would like level switch to control over a longer span (deep pit with higher flow rates at times) want to minimize cycles. Is there a different longer switch rod that can replace the stock version.

Jim, looking to understand the power consumption of the StormPro 1/2HP Model BA-50M pump. If its 1/2 HP at 120V, that converts to 375watts or 3.1 Amps by standard conversion. The pump is rated at 5.1 amps constant which converts to 615 watts at 120V or over 3/4HP. I'm trying to understand the difference and which one is accurate representation of power consumption.

I need to upgrade my pumping capacity - current sump pump (approx. 2400 GPH @ 10ft) was overwhelmed last season. I am looking at the StormPro 1/2 HP or 3/4 HP pumps. I currently have 1 1/2" piping and wondered if you could tell me what the actual GPH on both of these StormPro pumps would be if I use a 2" to 1 1/2" adaptor at the base of discharge and is this adaptor provided with these pumps? Thanks!

I have the StormPro 1/3hp pump and want to upgrade to the 1/2hp. My discharge pipes are 1.5 inches now. Will I have to change the discharge pipe to 2 inch or is there a way to make this work without changing all my piping?

What does "manual override" on the float switch mean? I have a 110 volt receptacle that is controlled by a float. Will this pump work with that receptacle?

How does the sump pump connect to the independent float switch, Does the pump plug into the switch and the switch plugs into the power?
from New Jersey 
February 09, 2011
Hi Jim. I know the float can be attached to discharge line. I'm wondering what the maximum On/Off points are. Looking to figure out how many inches of water will be pumped out per cycle. Thanks.
