A water pump is needed to get the water from your RV or boat's fresh water holding tank up to your faucets. This automatic pump from Seaflo not only performs this task, but it also ensures a consistent flow and high-volume output for up to 4 fixtures. This means you can run your shower and your kitchen faucet at the same time without losing pressure. It's also energy efficient and runs quietly.
No-Mess Self-Priming
There are 2 types of pumps you can get for your RV: one that requires manually priming every time you run your fresh water tank dry, and one that primes automatically. Manual priming requires that you pour water into the pump, which can be inconvenient and messy. This pump primes itself, keeping you and your RV clean and dry.
Worry-Free Operation
Seaflo uses an automatic start-and-stop pressure switch that lets the pump run dry long enough to self-prime. If you turn your water on and realize you've unknowingly run your fresh water tank dry, the pump can run dry without damage while you shut the faucet and the pump off. The pressure switch also protects the pump motor from overheating when the water has been on for a while. So, if one of your kids leaves the faucet on, you're going to town with the washdown hose, or your teen takes a long shower (despite your asking them to conserve water), the pump will kick off when it starts to get hot. Once the motor has cooled, it will automatically come back on if the faucet or shower is still turned on.
To use this pump once it's installed, you only have to turn the water on!
Quick Tips: Some of our neighbors suggest unplugging this pump when you're traveling to prevent it from turning on accidentally if your faucets shake. And some of our feline-loving friends also recommend unplugging the unit any time you leave your cats unsupervised.
Installation
This pump can be installed on the floor, under a cabinet, or on the wall. Because this pump has a vertical, priming lift, you can install it up to 6' above your fresh water tank. Just make sure to measure 6' from the bottom of your holding tank. This is where the intake fitting will sit.
Once you've determined the pump's location, it can be secured to its new home with 4 screws (not included).
A filter is included to prevent debris from entering the pump. To install this, just screw it inline with the inlet port.
The fittings on this pump are male NPT ports. Screw the 1/2"-14 NPT hose barbs onto the pump fittings. The hose barb fittings have wingnuts to make it easy to turn the fittings by hand. Once you have the tubing (sold separately) in place on the hose barbs, add hose clamps (sold separately) for extra security.
Fill your fresh water tank and turn your water faucet on to clear the lines of air. The pump should kick on immediately, but because self-priming can take up to a minute to complete, give it a little time to start producing water at the faucet.

I replaced my original 3gpm RV water pump with this. Didn’t have to make any adjustments with the water lines, they aligned perfectly. It would have been nice if the manufacturer included a female connector with pigtail to the provided electric wires and plug. I snipped that connector off and connected to the RV wiring with wire nuts. It took a long time to prime the pump to the point I was questioning if I mixed up the inlet/outlet or if the pump was working, but don’t give up!

@Thomas The hardest part sometimes is getting to the water pump, swapping it out is the easy part =) Glad we had the right replacement for you Thomas, and things are running as they should.
What kind of camper did this go in? What has been your favorite campsite of all time? I am trying to get a good list of camp sites together to share with other neighbors (customers).

The pumping capacity of this pump is too much for my application in my motor coach, it causes too much plumbing vibration (waterhammer) and is not variable speed capacity.

Larry

Very pleased at 1 year. This is the first pump I have had with the bypass function. It helps by lessening the pump cycling with low water flow at the faucet. This pump is also somewhat less noisy than our first and third pumps. Yes, we are on our 4th pump since new in 2014!. I have a really good feeling about this one now after 1 year and no glitches and still sounds the same as when I first installed it. Also it was an easy install since fittings matched the old ones.

We live full-time in our motorhome. Perhaps that is why we wore out 3 demand water pumps in the first 7 years. Now at the 2 year point with this pump and absolutely no problems to date. Very happy with this pumps functioning. I think SeaFlo got it right with this one.

The pump is wonderful. The only problem is that Etrailers video tells you it will work on a 17 amp circuit. The instructions from seaflo says pump should be wired on its own dedicated circuit to the battery. The electrical circuit for this pump requires a 25 amp fuse. I installed a continuous duty solenoid that supplies power to the pump when I turn the existing pump switch on that was it my 5th wheel rv.

It didn’t come with a lot of instructions with itself because when I hooked everything up properly, it hasn’t worked and is loud as hell

Thanks for taking the time to leave a review, Jamie. I'm sorry to hear you had trouble getting the pump up and running. Diaphragm pumps will make some noise during normal operation, but excessive noise or a pump that isn't working correctly can also be caused by things like trapped air, loose mounting, or an installation issue. I would check to make sure that it is secure to where you mounted it. Let me know if tightening it up does the trick.

I have water pressure!!! I couldn't believe how "weak" the old (original) pump was in this motorhome. It took some pipe modification to get it to fit, but I am glad I went with the most powerful unit I could buy. eTrailer was it's usual "efficient self", ordering was seamless and delivery was timely and efficient.

Doesn't work correctly, internal check valve not working as water comes back through pump when city water on.
Katrina B.
10/28/2022
That is a very common problem. The incoming city water pressure is too high. Incoming suction side pressure ideally should be 0 but no higher than 30 psi. There needs to be a regulator on the city water feed.

Thank you so much for the reply, I have put a regulator on hose and the new warranted pump works now!

The pump arrived on time and works well. I replaced the original pump in my Monaco motorhome and it is quieter than the one I replaced. The only problem I had was the box was open when it was delivered and I had to go buy o-rings for the fittings so they would seal. I would definately recommend this pump and etrailer.

That Seaflo # SE24FR is a solid choice for your Momentum 397TH and would be a nice upgrade from an older pump that’s starting to act up. It’s going to give you more consistent pressure than what you’re seeing at the park, and it’ll keep things steady whether you’re on city water or running off the tank. It does come with rubber mounting feet, which help cut down on vibration and noise, but if you really want it quiet, adding a short section of flexible...
view full answer... - Will Seaflo Diaphragm Pump part # SE24FR Have More Water Pressure than 3.0 GPM PumpHey Mitch, the Seaflo Diaphragm Pump part # SE24FR has a max output of 60 psi. It can provide pressure up to that high but it does not shut down or anything at higher pressures as it can get to a higher pressure. This can put out 2 more gallons per minute than what you have now so it would be an improvement for sure!

The Seaflo Diaphragm Pump item # SE24FR can indeed be ran for 10+ minutes without burning it out. It is designed for continuous use and has a 5-chamber design that minimizes heat buildup. What kind of trailer do you have? You can add this information, along with any other questions you have, where it says Add Comment.
view full answer... - What Water Pump Can I Use in a 2013 Heartland Cyclone 5th WheelHey, Jay! The Seaflo diaphragm pump part # SE24FR would be a great replacement for your existing pump. You always want to replace your pump with one that is similar in specs as the existing one. Since the Seaflo is 60 PSI and your existing one is 65, it's close enough that it would be perfect. How are you liking the camper so far?

We don't have the control module for the water pump on your 1997 Newmar, and since this is an older motorhome I'm not too confident you'll be able to find the part either. We do have a selection of 12V DC pumps that you might be interested in using to replace your whole assembly though. I really like the Seaflo Diaphragm Pump for Boats and RVs # SE24FR because it has a 5 Gallon per minute rating at 60 psi so it's in the middle of the road when it...

This is a variable flow based on demand, there is not an adjustable setting on the unit itself to make changes. If you are needing your pump to be within the 45-55 psi range you would want to go with one of the below pumps: - Seaflo Diaphragm Pump for Boats and RVs # SE58FR (45 psi) - Flow Max RV Fresh Water Pump # LC689052 (50 psi) - Seaflo Diaphragm Pump...

view full answer... - Can a Seaflow 12 Volt Water Pump Be Adapted To Run Off 110 Volt Power?If you would like to adapt the Seaflo Diaphragm Pump # SE24FR to run on 110 volt power you will need to find a power converter that is capable of putting out at least 15amps of 12 volt power. We have larger units like the Progressive Dynamics RV Converter # PD49RR that puts out 30amps of 12 volt power. You can also select the Seaflo Diaphragm Pump # SE96FR that has the same connectors as the other pump but is wired for 110 volt power.
view full answer... - Recommended Water Pump for An RV Using A Lot of WaterI recommend going with the Seaflo Diaphragm Pump for Boats and RVs - Variable Flow # SE24FR you were looking at. It sounds like you got a lot going on and are going to need a pump to keep up with those demands. The 5 GPM (gallons per minute) pump # SE24FR is going to be plenty. Most trailers and campers will use pumps that have a 3-3.5 GPM pump, but for larger motohromes that use more water you'd want to go with something in the neighborhood of 5 GPM or higher.
view full answer... - How to Choose Correct Size Replacement Water Pump for RVIn regards to replacing the water pump in a trailer, we simply recommend replacing this with a unit that carries similar specs to the existing as that is what was chosen by the manufacturer based on the several factors such as line length, line size, consumption etc. I wouldn't be able to inform of the maximum size pump you can use but so long as they are the same or just slightly higher than the existing pump there should be no issues. The Seaflo Diaphragm Pump for Boats and RVs part #...
view full answer... - What Causes RV Water Tank to Overfill When Connected to City WaterThe problem you are having is the check valve of your water pump leaking water and filling your tanks to the point of overfilling them. We actually don't carry the Shurflo brand so we aren't much help picking between the two models you have listed. Our most popular option is the Seaflo part # SE24FR which is rated for 60 psi and 5 gallons per minute. This will be a nice bump in water pressure above what you have now. This has a really solid check valve as well which will prevent the problem...
view full answer... - Recommended RV Water Pump For A 4 Gallon Water TankRV water pumps like the Seaflo Diaphragm Pump for Boats and RVs # SE24FR pressurize your trailer's plumbing up to their specific psi rating and kick on when the psi starts to drop. With you only having a 4 gallon tank you would quickly blow through the water in it with a pump so the # SE24FR is a bit overkill for your needs. I recommend going with a lower psi and GPM model unit like the Seaflo Diaphragm Pump for Boats and RVs - Variable Flow - 1.2 GPM - 35 psi - 12V DC # SE37FR. This...
view full answer... - Do I Need a Relay to Install Seaflo 5.5GPM On Dual SwitchesI confirmed with my contact at Seaflo that the # SE24FR does not require any relays to be installed in this manner, and you can turn the pump on and off in this installation method.
view full answer... - Can Brass Fittings Be Used With The Plastic Fittings On A Seaflo RV Water Pump Yes, since the Seaflo Diaphragm Pump for Boats and RVs # SE24FR has 1/2"-14 male NPT fittings for both to the inlet and outlet you would be able to use brass fittings instead of the included hose barb fittings, as long as you get the correct size and thread pitch. To thread plastic and metal fittings together, the male fitting has to be plastic, and the female fitting has to be metal. When fittings with a tapered thread such as NPT are tightened, the male fitting is compressed, and the...

view full answer... - Replacement Water Pump Recommendation for a 2001 Fleetwood CamperI recommend replacing your water pump with something that has a similar flow rate so you aren't downgrading from your current unit. For something slower I recommend the Seaflo Diaphragm Pump # SE57FR rated for 3 GPM (Gallons per minute) or for something a little faster we have the Seaflo Diaphragm Pump # SE24FR rated at 5 GPM. I'm linking review videos as well as our selection of replacement water pumps for your reference.

This water pump has a 55 psi rating with a 3.0 GPM rating. It has rubber feet to minimize the noise and vibration that you would feel with the other pumps we currently have available, especially the higher PSI rated Seaflow Pump # SE24FR. The # SE24FR is going to give you a higher GPM to negate that pulsating you'd have from your faucet, but its much noisier. The HydroMax does run off of 12v...

This pump will have the same 1/2" inlet and outlet hose dimensions as your Shurflo 2088-403-144 and will mount in the same manner, so it's a great replacement choice. This pump also provides the same 45 psi pressure as your Shurflo unit and pumps 3.3 gallons per minute, which is only .2 GPM less than the Shurflo unit.

After a year the water pump continues to perform flawlessly. We just experienced 3 days of hard freeze in Orlando and were using our tank water rather than city water and the pump performed exactly as expected. Appears to be a really good replacement pump.
