I installed the tap along with the Seaflo pump in my Hiker Trailer Galley. The combination works great together. See pictures below showing the installation.

Excellent pump. Hooked it up and it immediately started pumping water through the lines unlike the old pump. It’s pretty quiet and has decent water pressure.

Ask the Experts about this Seaflo RV Water Pump



  • Is Seaflo Water Pump # SE58FR a Good Replacement for Shurflo 4008-101-A65
    I checked out the specs of the Shurflo 4008-101-A65 and the Seaflo Diaphragm Pump for Boats and RVs # SE58FR that you mentioned would be a great replacement as it has the same flow rate of 3.0 gallons per minute.

    Yes, the Seaflo Diaphragm Pump for Boats and RVs # SE58FR does include a strainer.

  • Difference Between, and Power Supply for Seaflo Diaphragm Pump
    The difference between the two pumps is that the Seaflo Diaphragm Pump for Boats and RVs # SE58FR has a 3-chamber diaphragm for water flow up to 2 fixtures, while the Seaflo Diaphragm Pump for Boats and RVs # SE57FR has a 4-chamber diaphragm for water flow for up to 4 fixtures. In regards to power supply, according to the manufacturer these each require their own dedicated circuit and are 12 volt only, with the red lead going to the positive terminal of your battery and black lead going...

  • Recommended Replacement for Shurflo 4008-101-A65
    Per the specs of the Shurflo 4008-101-A65 it looks like we have two very good options in the HydroMax RV Fresh Water Pump, # P25201 and the Seaflo Diaphragm Pump for Boats and RVs, # SE58FR. Each are 12VDC pumps and rated at 3 gallons per minute and receive great customer feedback. I suggest the the HydroMax RV Fresh Water Pump, # P25201 because of the slightly higher pressure of 55 psi over that of the Seaflo's 45 psi and the additional amount of customer ratings that this pump has received....

  • 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.

  • 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.

  • RV Water Pump Replacement for Shurflo 2088-422-444
    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.

  • Galvanized Wheel and Tire With 6 on 5-1/2 Inch Bolt Pattern
    You can go to a smaller wheel and tire, and the smallest option we have for a galvanized wheel with a 6 on 5-1/2 inch bolt pattern and trailer tire is the Karrier ST225/75R15 Radial Trailer Tire with 15" Galvanized Wheel # AM32666. So you will want to take a quick measurement just to verify but this should be perfect for the space you have. This wheel and tire combo has an 8.9" width and 28.4" total diameter and is a very high quality wheel that is galvanized like you were looking for...

  • 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.

  • Recommended Single Rocker Switch For Powering An RV Water Pump Off And On
    Yes, the Single 12V Rocker Switch # 37213405 is exactly what you need to power your water pump on and off and can be easily spliced in-line. We also carry the Single Rocker Switch # 37212525, which has an illuminated switch to easily show you when power is running to the pump.
