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 2 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.


Seaflo pumps for RV fixtures

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. Also features an internal check valve that prevents backflow contamination of your clean water supply.


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.


Pump feet and mounting pattern

Once you've determined the pump's location, it can be secured to its new home with 4 screws (not included).


Filter

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.

This RV water pump was relatively easy to install. I used it to replace an older pump that came with the trailer when it was new in 2006. This pump is much quieter and puts out an excellent amount of pressure. So far, I give a very good recommendation for this water pump.

  • Can the psi be of the Seaflo 60 psi Diaphragm Pump Be Adjusted
    No, the Seaflo Diaphragm Pump, # SE24FR is a 12 VDC pump that flows up to 5.5 gallons per minute and pressure setting at 60 psi. 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...

  • Replacement Seaflo Diaphragm Pump Options for a Shurflo 4008-101-A65 Water Pump
    The Seaflo Diaphragm Pump for Boats and RVs # SE58FR has the same 45 psi rating as the Shurflo 4008-101-A65 so it would be the closest match, but as long as your setup is able to take the higher 55 psi pressure rating of the Seaflo Diaphragm Pump # SE57FR then it will be perfectly fine to use. The GPM rating is still 3 though so the only real difference between the two is the psi rating.

  • Recommended Replacement For A Shurflo 4008-101-F65 RV Water Pump
    Hi Dorothy, The Seaflo Diaphragm Pump # SE58FR would be a compatible replacement for your Shurflo 4008-101-F65, but it has a lower psi rating so you'd see a bit of a drop in pressure. Instead I recommend going with the Seaflo # SE57FR. This unit has a 3.0GPM, 55 psi rating, and operates on 12v DC power. Everything I can find on the 4008-101-F65 shows it being 12v DC but we can clear up any confusion by checking where it gets power from. If it runs to the battery or to a fused port on...

  • Are Replacement Gaskets Available For An Artis RV Water Pump
    you would need to reach out to the manufacturer in order to get a replacement gasket for your Artis Water Pump. If you can't get the gasket or decide that you just want to replace it instead then you'd want to go with the Seaflo Diaphragm Pump for Boats and RVs - Variable Flow - 3 GPM - 45 psi - 12V DC # SE58FR. It has the same 3 gallons per minute flow rate at 45 psi (your Artis is 40 psi) so you won't be sacrificing any performance. If you do replace your unit then I recommend checking...

  • Replacement Waste Valve And Fresh Water Pump For A 2012 Forest River Sport Surveyor
    Hello Sandy thanks for the picture. The valve in your picture appears to be a double waste valve like the Valterra Motorhome San Tee # T18A. This valve uses a 3" spigot with a 1-1/2" hub off to the side, both of which are the standard valve sizes. You could always measure the current valve to confirm this, but based on what I can see in your picture, the # T18A will be exactly what you need. As far as a fresh water pump, they are all fairly universal, it really comes down to your requirements,...

  • Can The Excel RV Tankless Water Heater Be Installed In A Van
    Yes, but the Excel RV Tankless Water Heater # EX93FR requires a water pressure of 2 psi up to 120 psi to properly function. You would need a pump to create the pressure for it to operate if you're pulling from a 7 gallon tank. I recommend the Seaflo Diaphragm Pump for Boats and RVs # SE58FR with its 3.0 GPM and 45psi rating. Other than that you'll just want to mount it in a well ventilated place with 3" of clearance on the sides and 8" of clearance above.

  • Replacement for Shurflow 2088 403 144 RV Water Pump
    Although the Seaflo # SE58FR pump has a slightly lower flow rate (3.0 gpm versus 3.5 gpm for the Shurflo) it should still do a good job for you. Both pumps operate at 45 psi pressure, and have the same mounting dimension and are both compatible with a 1/2 inch hose. If you'd rather get closer to the original flow rate, the # LC689052 LCI Flow Max has a 3.3 gpm flow rate, operates at the same pressure and is compatible with the same hose diameter.

  • Recommended Tankless Water Heater And Water Pump For A Food Cart
    For a small food cart the Excel RV Tankless Water Heater # EX93FR is really going to be the only option as the other water heaters are all quite large and would use up too much space on your cart. This system can mount right to the side of your cart and is lightweight. For the water pump I recommend the Seaflo Diaphragm Pump for Boats and RVs # SE58FR. It's going to provide enough water pressure for the # EX93FR to run properly.

  • Troubleshooting A Fogatti Tanjless Water Heater That Goes Cold But Doesn't Have An Error Code
    If the hot water from your Fogatti RV Tankless Water Heater # LSB64FR is fading back to cold it could be for the following reasons: If you have a lack of lp gas pressure the unit won't be able to keep up. Typically you would get an error code with this. Since you're not it leads me to believe that it's either a water pressure issue or electrical issue. Check the water pressure at the unit to ensure it's getting around 40-50psi so that it can keep up with the demand at the point of use...

  • Replacement Water Pump for ShurFlo 2088-408-444
    It looks like your old Shurflo mode 2088-408-444 pump had 2.8 gpm flow at 40 psi pressure, so the Lippert # LC689052 that you were looking at would be the most comparable replacement and what I recommend using.

  • What Diameter Supply Hose Is Needed For The Seaflo Diaphragm Pump
    The Seaflo Diaphragm Pump for Boats and RVs # SE58FR requires a 1/2" hose diameter hose. If you're using the fitting included with the pump that allows you to slide a hose without a fitting over it then make sure you tighten it down with a hose clamp # H03-0002. If you need some hose without the fitting on it then you can use the Valterra Braided PVC Tubing for RV Fresh Water # W01-1800.

Each are 12VDC pumps and rated at 3 gallons per minute and receive great customer feedback.

    I recommend the Seaflo Diaphragm Pump for Boats and RVs # SE58FR to replace your current Shurflo 2088-422-444. The Seaflo is 12v and 45 psi just like your current Shurflo but has 3.0 gallons per minute compared to the 2.8 gallons per minute your Shurflo is running at. The Seaflo also comes with a 4 year limited warranty compared to a 2 year limited warranty that its counterpart the Flow Max RV Fresh Water Pump # LC689052 comes with.

From there you'd just match it with a model that has similar specs. The most common option for RV's is a 3.0gpm and a 40-50 psi rating like the Seaflo Diaphragm Pump for Boats and RVs - Variable Flow - 3 GPM - 45 psi - 12V DC # SE58FR. If you can...
