Ease Of Use
This pump features industry standard fittings, wiring, and mounting base to directly replace similar competing pumps.
Beats The Competition

---|---|---|---|
Diaphragm PumpsRanging from 1 to 5 GPM capacity, SEAFLO automatic demand water pumps have a built-in pressure switch which automatically starts and stops when the faucet is opened and closed. They're easy to install, service and winterize. |
Bilge PumpsThe SEAFLO Submersible non-automatic bilge pump line handles bilge water evacuation and is controlled by a panel or float switch. They all include Anti-Airlock protection and moisture tight seals with marine-grade blocked wiring. The removable strainer base fits industry standard mounting conventions, so you’ll have no problem swapping to SEAFLO. |
Washdown PumpsSEAFLO’s washdown kits are the best choice for cleaning boats, fish boxes, anchor wells, dinghies, and other similar applications. Ranging from 3 to 5 GPM capacity and with an on-demand switch, the pump automatically turns on when you squeeze the spray gun handle. |
Seaflo Dry Bilge SystemThe SEAFLO Dry Bilge System is the most economical and reliable way to keep your bilge clean and completely dry. The SEAFLO Dry Bilge System removes all still water from the lowest part of your bilge, or other water-containing compartments. The system is self-priming up to 25 feet, so it can be mounted remotely from the suction foot. The system is activated either by the easy-to-use programmable timer, or manually by a toggle switch. |

There was a problem filtering reviews right now. Please try again later.
Beyond just the performance, it just looks, and feels like a much more quality item than what my RV came equipped with. I could tell that it was factory tested as there was a little bit of moisture inside the plastic bag it was shipped with, obviously they are manufacturing with quality control in mind.
If you’re on the market for a replacement pump in your RV, I highly recommend you consider this one. It’s a great value for the price point and I’m very pleased with the performance.
The variable flow and smooth, quiet operation (at lower GPM) sets this pump apart from many others I've used. Additionally, the price good (almost half of some other ones I was considering).
I just got this pump today, so I can't comment on longevity. However, it seems like a solid, quality product, at this point. The above mentioned features and value have made me happy. :)
Sure it is quiet, inexpensive, good psi, boasting low flow capabilities and an impressive warranty (granted I still needed to install an accumulator tank because mine still cycles, and people have reported they don’t honor their warranty) - but the pressure switch on this has caused catastrophic issues for many people (just search YouTube); as far as draining freshwater tanks out at sea due to melting the plastic water joints (not to mention potentially starting a fire).
Well, its not a myth. I’ve pumped maybe 100 gallons simply to test the water system I installed in my sprinter. Worked great, so I thought maybe those people had it in too humid environments for too long and that caused the issue (still shouldn’t happen on a water pump, but ok you get what you pay for).
Well, brand new pump… Dry location… Still returnable to Amazon… It seemed to work fine so I took a trip (I’m still on the trip trying to get a new pump sent to me on my way).
First night (last night), it started shorting out when it reached pressure, just as it has been cautioned in the videos I have watched. It shorts enough to make an electrical short crackling sound and make the lights in the van flicker while the pump rapidly cycles on and off, but not enough to trip the fuse. Plus it still pumps water… for now…
As such, I can certainly understand how if this was out of observable range (acoustically or visually), and not tampering with sensitive lighting dimmers (different circuit, non-isolated, same power source), one would not necessarily know that it’s shorting out until it’s too late and has melted itself, and potentially the connected plumbing (which is how this has unknowingly drained freshwater tanks at sea)…
Thankfully I’m still under Amazon’s return window (yes it’s that new), and they will honor the return, otherwise I’d have to deal with the seaflo warranty that they don’t seem to honor (read reviews of them delaying by months, or going MIA, or even going as far as just telling people to just bypass the pressure switch and keep the faulty unit).
I decided to buy a higher quality pump for peace of mind. And I’m not even out at sea. But the possibility of a fire? Or suddenly draining the freshwater tank into my van? Perhaps while 5 days out into the desert?
Nope.
It’s a known issue and simple fix seaflo. You could literally be the cause of someone’s demise for not just fixing this issue. It’s not just inconvenient; it’s potentially someone’s life if they are weeks from land or way off grid.
Buyer beware.
