SEAFLO 12V 56A Series 5.0 GPM Variable Speed Smart On Demand Marine/RV 5-Chamber Diaphragm Pump

The end fittings are different than other pumps, so you might need to go to a hardware store to get some adapters .

I spoke at length with the engineer at Sea Flo before making this purchase, and at face value it seemed like the perfect pump for my need in using it with a 12 volt battery to give me running water when there is none. When I got the pump, it came with a very short wire, maybe 5 inches long, so that one would have to hire an electrician to lengthen the wire with 16 gauge wire so that it could even reach my 12 volt battery, the connection would have to be "heat shrunk", and in the instruction booklet it states that one must install a fuse (not included) "in line". Adding several feet of 16 gauge wire and putting a fuse in line all with heat shrinking is nothing I could do, and so I had to hire an electrician to do this for me. This drove the price of this pump way out of range for me. It doesn't state anywhere in the item "write-up" that the electric wire from the pump is so short, nor needing the addition of an inline fuse, and nothing about heat shrinking any of these alterations. SeaFlo really goofed on this one as I won't recommend this pump to anyone, due to the extra cost to me, to anyone. It would have been very easy for the company to make the electrical connection much longer with an inline fuse, charge more, and then it would have been plug and play as one assumes without the needed directions/diagrams that is not there on how to assemble, not even a diagram of where the extra parts go, no directions on how to assemble or what each part that is in a plastic bag is used for and how to asssemble it for use with the pump. In addition there is no diagram showing where parts should be placed, and there is a list of additional parts that are needed and not included with the pump package. Very poorly done, Seaflo, and you have misjudged your customers in the day of "'preparedness", and the number of women and men who have little to no knowledge of pumps, assembly or external parts and where they are placed. You need to use a different person to write your manuals for the "lay" person who needs this kind of pump and one who has no prior knowledge of pumps, their parts, how they work, and how to assemble and use them. Pump may be great once it works, but I never would have purchased it if I had known about all the additional costs and expertise needed to just assemble it for use.

Ordered and arrived earlier than anticipated! Already installed and it and it works as advertised!

Pump is great but went through all three fittings to find on that didn't leak. All good now.Flow good, quieter than old pump.Thank you

I use this in conjunction with a higher powered pump. It works terrific. I can only get about 3 gallons per minute out of it. But that’s enough to run two showers at the same time. I have it in line with a large pump that uses a lot of electric electricity which comes on if I turn on a garden hose or something. The only thing I don’t understand is why they don’t include one more half inch threaded fitting. I think you should have the choice to use slip on tubing or threaded fitting. You have to buy extra threaded fitting which you can purchase, but you have to get four of them.

I've moved thousands of gallons of water with these pumps. Consider adding a larger in coming filter.

I live off grid in a 44ft toy hauler mostly alone with guests on occasion. I purchased this pump because of the good reviews on Amazon. My experience has not been great. The pump works as advertised when it is working (that's the trick, when it's working) I am writing the review as a warning on reliability. The first one worked for about 20 days. I could hear a humming noise even when it was not pumping. I would not turn it self off when it reached pressure and was sucking my batteries down. I returned it to Amazon no problem. The replacement worked until last night when I was taking a shower. The water pressure began to drop and I still had some soap on me. I checked the bathroom faucet and no water pressure there either. Check the fuse and this morning put a meter on the connection and there is 12 to 13 volts at the pump. The pump will not run. I have contacted Seaflo from the amazon site because this one was purchased April 12, 2023 and now it June 16th, so just over 60 days and beyond the return directly to amazon window. I hope Seaflo will send a replacement that will last a few year instead of a few months.Update: As of July 10, 2023 I still have not received any contact from Seaflo. I purchased another pump as I need to have water available. Super inconvenient glad I purchased a backup.

After further review I am liking this pump more and more. It took a bit to adjust it for my system and but I got it working as advertized. I love the flow and water pressures it delivers throughout my Class A MH.this pump does not have a check valve, so! if you are an RV or Motorhome owner be aware. Un regulated City water pressure can slowly back feed and pass through the pump and will fill your Fresh Water Tank and overflow it. I installed a valve on the outlet hose and use a pressure reducer at my fill connection. I haven't had any issues since, and I would recommend this pump. JFK, I own a 2005 Winnebago Adventurer 35A, on W24 chassis. Hope this helps
