I see there are multiple models of the Basepump. Can someone please explain the differences and suggest the best for normal conditions (no flood zone)

There are two base models. One has a higher flow rate than the other. That means that more water can be moved faster that the other. But both flow sufficiently well for most enviorments. The other things that are added may be desired for some applications. You need to check with you local plumber to see what is required in your area.

I have installed the RB 750 as backup pump a year back. The pump has been working well so far. Will surely recommend it.

Use the manufacturer's recommendations to determine which is best. How high will the lift be, what is your water pressure, etc.

The biggest advantage I found was the amount of water being moved. This pump far exceeds the standard, inexpensive, in-sump pumps. It all depends on how much water you get and how much you need to move.

Water pro here. It will work marginally at these low pressures. The membrane does the fine "cleaning" and will not be as effective and be short-lived unless you have pretty good water to start with (and even then 30psi is likely too low). A submersible pump with 40-60 psi is good (and can be set higher than that). The above ground ("jet") pumps don't do as well. The booster pump typically get's it up to around 80psi. Water pressure is the force that drives and flushes the system. City water that I've seen is usually about 50 psi.

With using an electric bed pump, i just pumped it up until it cant push anymore air in the boat, you can tell kinda like blowing up an air mattress. The air valves have the safety valves which only let in air and for the big chambers you push the lip and it keeps the air from coming out. The only ones you have to be quick with are the seats and if you have the Coleman 12-Volt DC QuickPump, there are no issues at all cause it comes with the adjustable heads for each chamber.

I purchased this model pump to heat my shop from my geothermal well. It works great, but I was not replacing a pump. It was a new application. Have you tried calling or e-mailing Grundfos to ask about the pumps replacement compatibility? I did replace a Bell & Gossett pump that heated my house with a 1/6 HP Grundfos pump. It too works much better & quieter than the Bell & Gosset. When I contacted Bell & Gossett to try and get info about their replacement pumps, oddly the representative their would not give me the Bell & Gossett replacement pump number . I assume it had something to do with their desire to support local contractors/plumbers, but all it did was upset me enough to buy a Grundfos instead of another Bell & Gosset. Best decision I mad. Wouldn't buy another Bell & Gosset. Grundfos is a muc.better pump.

Can't seem to find any difference between the two. Both come with 2011/136x/115x part. Both look visually the same, both have the same pump. Perhaps just a different naming code from the factory? I would buy the $50 one. I have it, and it runs like a beaut.

The "c" model uses a CAT brand pump. These are very reliable, rebuildable, and professionals usually prefer them over other brands. The "A" model uses an Annovi Reverberi pump. Annovi Reverberi is an Italian company. They also produce a high quality rebuildable pump. I'm not sure where either pump is made. Cat pumps used to be made in the US, but I'm not sure anymore. They've probably moved manufacturing to china like everyone else. Either way, these are two of the best pumps you can buy. I went with the CAT model since CAT is an American company and they seem to be the pro's choice.

I've used the Floodstop products for self, family and friends on all types of approved water supply lines including PVC without any issues. Other Floodstop products are used for washing machines (Highly recommended) , ice makers and can be adapted to virtually any device that uses a water supply line, such as a whole house water filtration system. (No, I do not work for Floodstop) On a maintenance note, I recommend a manual check of the valve operation and backup battery voltage at least twice a year. I've had valves fail, particularly on hot water heaters. Could be heat, contamination or some other problem. This usually occurs after many years of use.

I believe the only difference is in the construction. The M57 is a little more heavy-duty. As far as I remember, the entire 50 series moves the same volume of water. I think the model you choose is based more on the application. If the pump is going to be in harsher environment, you'd probably be better off with the M57.

Hi Rolf...not too sure of your question, but when i had it we used it for our septic tank (in the caribbean)...it was okay...the sceptic was about 5-6 feet deep. Honestly it was a bit sometimish (as in sometimes that ball thing wouldn't activate the pump). we got a new one recently for another part of home....We live near a lagoon and its filled land so when the tide is high sometimes the water backs up...the one we got is the Red Lion Rl-SC50V 1/2 HP Cast Iron Sump Pump with Vertical Switch. its available on amazon...highly recommended. it has a much better activator switch (im sorry im not into the correct technical jargon)...hope this helps...but the pump you're asking about was still pretty good Hi Rolf...not too sure of your question, but when i had it we used it for our septic tank (in the caribbean)...it was okay...the sceptic was about 5-6 feet deep.

I would like to give you some input but just brought it out to the shop to test. i had purchased other pumps that claim to be high temp but failed within hours and in cold water. My desirefor this pump is to circulate water or coolent exchange for winter water heating and space heating. Looking at this pump with x-ray eyes has determined that the configuration is much like oil pumps in the industry. First seen it on the old VW's. Looks reliable so long as the motor is bearinged and not bushinged. Mark

I don't know the difference. If one model is newer than the other, go with the newer model. Zoeller pumps are high quality. I have never had trouble with any Zoeller pump.

All I can say is that this is the best pump I have owned and I used to replace one every other year. Also, I have two pumps in one sump well; one is set about 3 inches above the other. When it rains really hard, I need both pumps going at once.

It would be preferable to have both primary and backup pumps sitting on the sump floor. You want both pumps stable and both floats unobstructed. Tweak the float for the backup so that it kicks on if the primary float doesn't then run a test to confirm that. I personally would not advise hanging it above the primary pump. Hope that helps

I looked at both just now on Amazon and aside from a $20 difference (the D50AP is cheaper) I don't see anything that jumps out at me as being different. The dehumidifier has been plug in for over 4 months now and now that the weather has gotten sticky it's been going nonstop without a hitch. The pump is working fine but it's a bit noisy still it's better than emptying a bucket every day!

Hello J. Taneri, I've never really pumped any distance with mine the only info I could give you is what I have done with mine-I've pumped from a stream- with the pump drawing the water from about 8 feet down to a barrel in my Jeep and the discharge hose is app 12 feet long. It took awhile to fill the 55 gallons maybe about 3 gal per minute. Maybe I was over exerting the pump the way I was using it??? I failed to prime the pump one time i got too impatient and burned the impeller. I got a replacement and it works fine again. any other questions please ask. jerry mayers Hello J.
