If you need the extra flow rate, go with it, otherwise the L1 is highly recommended. Not sure of the customer service and reliability of those pumps. Almost looks like a pump from the same manufacture as the Jebao pumps. Return pump is an important part of your system, so make sure its reliable.

In doing some research, the deepwater pumps are not made by Jebao. They are made by another Chinese manufacturer. It was suggested that the motor core is from Eco Tech. I'm still researching that information.
The pump has not been around for very long, but most reviews seem very positive.
I did call Eco tech about their flow rate vs head loss. What was disappointing to find out is that eventhough their pump outlet is 1" the flow chart is based on using a 1.5" hose. Now I am planning on using a 1.5" line so I was hoping the flow would have been better using a 1.5" line. So their flow rate chart is a little misleading.
My tank will be around 300 gallons and I was looking to get around 3,000 gph to the sump. With the Eco tech L1 I would need 3 pumps. With the Deepwater BLDC15 I would only need one pump. Most likely I will use 2 and just run them at a lower rate, but if I want to go higher on my flow rate the pumps will have the capacity.
I'm currently having a house built, so it will be awhile before I need the pumps. I will keep watching the forums to see how the pumps continue to hold up or not overtime.
I was considering a BLDC15 a while back because it's performance curve was a very good match for my setup. It seemed to be the only reasonably priced submersible pump that could put out the flow I was looking for at about 15 ft of head. When I contacted the company for some information, I was told that they were redesigning the housing to reduce heat, and that the pumps would be available "late June". In June, I asked again, and was told "late July". In July, I was told "late August". I gave up and went with an external pump for now (Reeflo Hammerhead), with the intent to switch to a submersible when/if a viable product shows up in the market.
Just for fun, I put a "notify me when available" watch on a certain online vendor's website, and just today received an email that the pumps are back in stock. I assume that these are the new design - but you may want to contact DeepWater Aquatics directly to learn more. I found the online chat function on their website (during business hours) to be surprisingly responsive ...

Thanks for the insight, I will have to check out their chat function.
Ah, I forgot you are in the advanced planning stages.
I did chat with someone on the deepwater aquatics website today, and they told me that the new version of the BLDC15 pumps are available. The changes are that the power supply is a Meanwell brick, and they have made the impeller enclosure stronger. I was told that the pump needs to be run submerged, not sure if that is a change from the old model.
I may pick one of these new versions up and give it a try. Like you, I have time now, so I will probably wait until I can catch a sale ...

I haven't heard of them. I will see if their head loss graphs are available. I need a pump that can handle a head loss of 14-15' with a 1500-2000gph flow. I also want a DC powered pump.

If the budget allows for it, there is nothing better. Public aquarium grade (and proven), and a 10 year warranty.

I have a smaller Deepwater BLDC 8 and have been very happy with it so far. I have only had it about 5 months so hard to say how long it will last. My research indicated they are not made by Jeabo and are much more reliable. I actually bought two pumps just because I couldn't find any real long term experience with them, that way I would have redundancy. The DC eight I bought is capable of totally draining the return section of my sump, so I never installed the second larger pump.
There really is no benefit to running that much water through your sump on a 300 gallon tank I would aim for a little bit more than half that, that way you have extra capacity, but 1500 gph is plenty.

I installed 3 return lines from my equipment room to my big tank. I figured I would use 2 and leave the 3rd as a spare. My thinking was that I would use 2 of the deepwater pumps so that I could run them at a lower flow to lengthen their life and not put as much strain on them. Plus with 2 pumps running at half speed, if one fails I still have the second one running as a backup. In addition my sump can hold 200+ gallons of water. Lots of water reserve.
