Seaflo RV Fresh Water - 4 Fixtures Diaphragm Water Pump - SE57FR Review


Hi there I'm Michael with etrailer.com. Today, we're going to take a quick look at the Seaflow diaphragm pump. This is going to provide a consistent high volume flow of fresh water to up to four fixtures in your boat or RV. This uses a variable flow technology to help provide the amount of water that you need without having to cycle. So basically when your faucet is turned to the open position, the built-in pressure switch is going to start the pump. And then when you turn your faucet to closed, it's going to stop the pump.

It does have a four chamber diaphragm that's going to provide up to three gallons per minute of flow at 55 pounds per square inch of pressure. So it's going to be basically the same thing as your home faucet, maybe even a tad bit higher. So you won't feel like it's just trickling out. It's going to give you the same pressure that you're used to.This does have a self priming design that removes air from the pipelines, help eliminate air binding. So you're not going to get the spluttering that you sometimes get with pumps when there's air in the lines.

This unit is capable of up to six foot lift. So if you have this underneath your sink and you're wanting it to push the water up to your shower head, you're going to have six feet of room to work there. This does have a heavy duty corrosion resistant motor, which is going to run dry without causing any sort of damage. Our hose attachments here, our hose barbs, attach to half inch inner diameter tubing. When you are installing this, you want to make sure that you're leaving enough room so that you're not crimping your tubes, you're going to have a nice gentle corner if you are making an angle.As far as the installation goes, this is a bolt-on installation.

So you can see our feet here have bolt holes there to get it in place. It can be mounted in any orientation. The hardware is not included with this. So you will have to provide that for yourself. One thing to note, because electricity and water obviously don't mix very well, it is recommended that you keep the motor above the water portion of the pump if you are going to be mounting it vertically like this.Obviously, when you're installing, you want to make sure that it's going to fit.

So as far as our dimensions go, this is right at about eight and a half inches long. When we have all of our fittings installed here, it's going to be about 10 and a half inches wide.And again, you do want to make sure that you're going to have enough room for your pipe tubing to be attached there. And then for our height, right at four and three eights, just over four and a quarter of an inch. And our mounting distances from center to center of our mounting holes here are right at about three and a quarter of an inch and two and seven eighths of an inch there. Now these feet are a semi-rigid rubber and that's to help to absorb any excess vibration or noise. So when you're installing this, you do want to make sure that you're not tightening it down so much that you're causing that rubber to compact. You want to make sure that it's going to have the full ability to absorb that vibration.This is going to work for your 12 volt DC systems. It is only going to draw about 7.5 amps, so shouldn't pick up much power at all. It does have an enclosed housing with sealed switches that help to block moisture from getting inside. But as I said earlier, you just want to take the extra precaution to make sure that your water isn't going to be in a position where it can drip down.This does have a maximum water temperature that it can handle, 140 degrees Fahrenheit, which is actually 20 degrees warmer than the Consumer Product Safety Commission recommends for your water heater. So it should be able to handle just about as hot as you can handle essentially. So you're going to have nice warm showers and nice hot water to wash your hands and everything that you need. So keep in mind, this is going to provide that pressure for up to four fixtures. If you do need a little bit more, if you've got more fixtures that you're wanting to get water pressure to, we do have other options here at etrailer.com that go up a little bit higher, so you might want to check those out. But if you're only needing the four, this is going to be a great option for you. So that's going to complete our look for today. Again, I'm Michael with etrailer.com. Thanks for watching.
