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?

Re: the Storm Pro BA-33M 1/3 HP. Ok, I cannot visualize the set up for this pump. It looks like the cord goes under water and that does not look safe at all for a sump pump! I have a tub to line the hole it goes into and do you put both units under water? Or below the floor line and eventual water?

I was concerned that as often as our pump works I should have a replacement pump in case the primary fails and an alarm if the power goes out. i was thinking of a pump that is more quiet and then using our old one as a backup. i'm not sure if I like the idea of a battery backup. any suggestions?

I recently purchased a BA-33 sump pump. Is it necessary to drill a hole in the bottom of the discharge pipe? Also how do I install the switch on the discharge pipe to maximize the run cycle? Is it adjustable? Finally- is it OK to go from 1 1/2" ABS pipe comming out of the discharge fitting to 1 1/4" id black plastic where it exits the house [about 7' above the pump] The 1 1/4" black plastic carries the water along and away from the foundation with a steady pitch for approx 30'.

I recently purchased Stormpro BA-33M. I did not get the check valve. I picked up a check valve at a local plumbing outlet. The pump would not work at all with the valve installed, i have installed several of these and was careful to install the valve with the direction correct. I installed the pump without the check valve and it seems to work fine. Will this affect the life of the pump, or cause any problems? It has about a 10 ft. vertical lift and simply drains off into a ditch. Thanks.

Jim, Researching sump pumps and leaning towards the purchase of a StormPro BA33 with adjustable height switch. (good reviews) My question is can I purchase an additional switch for my secondary pump? I'm not sure what the model number is and the cost involved. Also, during my wet season, this pump will actuate every couple of minutes. I'm concern over how long the switch lasts! What do you recomend? Several of my pumps have failed due to the switch! Thank you in advance for your help. Joe

Hi Jim, I just bought a StomPro BA 33M sump pump.I would like for it to go "ON"at 9 or 9.5 inches.Where on the discharge pipe "height" in relation to the pump body do I attach adjustable switch? At contact pt with float at top,midway of pump body? Thanks so much,Marvin

Hello Jim, I have an old Zoeller sump pump that does not seem to be able to keep up with demand (possibly overheating). I have an 18" diameter by 18" deep hole and I would estimate during peak rain periods a need for a pump to remove up to 36 gallons per minute. This pump seems to be able to do 50 gallons per minute. Is the 1/3 HP StormPro a good choice or should I go to the Simer 3995 I'm considering? I can't determine the current horsepower on my Zoeller...

Hi Jim i have a single sump pump that is only in a 2x4 foot rectangle that they left out of the concrete when they built my house . it is open to the air and water is always about 6 inches below the surface. I have a single sump in there now that keeps it from entering the basement and there is a low spot that has another pump that sits on the surface and routes its water to the primary. I wanted to enclose the pump and also get something powerful enough to keep that water lever down. i also donot want to be fighting the water table if that is the issue. ( it is very high) what kind of pump , enclosure , and system would you recommend...thank you , Jason

Jim, What is considered continuous duty applications. My present pump can be on in as little as 1 min intervals. Has operated for several years as such. A True Value Master Mechanic pump. Afraid will one day quit. Reason for shopping for replacement.

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?

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.
