  • Works well
Size: F42-12V 5.5GPM 70PSI
Plenty of pressure for 1 sprinkler, maybe 2. Very pleased with this product. Quite & efficient I've run 1700 gallons this month, doesn't require much power. Ways cheaper than running the Well pump Hard pipe inlet, it will collapse a garden hose on the inlet side. Worked out Great for my application

  • Efficient and Reliable RV Water Pump with Excellent Customer Service
Size: F42-12V 5.5GPM 70PSI
I've been using the RV Fresh Water Pressure Pump 12V 5.5GPM 70PSI in my Travel Trailer for a few months now, and it has been working flawlessly. The pump is quiet and draws very little power, which is important when you're running off battery power. Initially, the pump was delivering water at a pressure that was a little too high for my liking, but I was able to adjust it down to 55psi and it's been working great ever since. I've had no issues with low water pressure, and the pump has been able to keep up with my demand for water. I also purchased the 5.0GPM 55PSI 12V model, but had an issue with the pressure switch. However, the company was quick to resolve the issue and I was very pleased with their customer service. Overall, I would highly recommend the RV Fresh Water Pressure Pump 12V 5.5GPM 70PSI for anyone looking for a reliable and efficient water pump for their RV. Just be sure to adjust the pressure down to your desired level and you'll be good to go! ... show more

  • still works but sounds different after about 50 gallons
Size: F42-12V 5.5GPM 70PSI
I used this to upgrade a 15 gallon herbicide sprayer on my ATV. It worked great for about 50 gallons or so then the sound of the motor suddenly changed. It still works but the sound changing makes me a bit nervous about how long it will continue to work.

  • Broke within 10 minutes! Terrible product - useless - pump burst at seams spraying water everywhere
Size: F42-12V 5.5GPM 70PSI
I connected this to my house outdoor water spigot to power several lawn sprinklers - since my home water pressure wasnt good enough and I was hoping this would boost the pressure. Well in the 10 minutes it was actually on - it barely increased the pressure. It was almost an unnoticeable difference. Then its supposed to have an automatic shutoff when there is no water coming in, and that wasnt functioning, so it would keep running continuously whenever it was plugged in. And finally in 10 minutes, the entire pump housing burst, with water spraying out from all seems. Could not rate this any lower! Wish i could get my money back because it is a completely defective unit, but i didnt have time to try it until after my return window. Hope seller does the right thing and refunds my money. ... show more

  • Perfect for Offgrid Shower and Laundry
Size: T33-12V 3.5GPM 45PSI
I paired the unit with a 100 watt Renogy Panel and a small EBL Solar Generator and a Gaveenon Instant Propane Water heater and a 12 volt cigarette lighter style extension cord and ran the water line to an adjacent IBC tote to create a shower in the porch. All items except the water tote were purchased on Amazon. Adjacent to it, I put a portable washing machine, also bought on Amazon. The pump is on demand and works strongly to provide for all of my needs. This is my second unit because the first was outdoors and the wiring sheath is made with a soy based plastic that desert rats eat. When I went to replace the wires on the first one, I did NOT realize the unot jad internal spring loaded brushes. I thought it was brushless. So...when I removed the housing, the springs shot off into the sunset across the Sonoran Desert Wilderness! It was morw cost effective to replace it than sourcing springs...a good and solid unit! ... show more

  • First pump did not work
Size: T33-12V 3.5GPM 45PSI
EDIT: Pump has been replaced with a new pump! I have had this pump in my RV since I purchased it 3 months ago to replace an old pump that failed. I know that my water system (other than the pump) is all working properly as it had no issues with the old pump. This pump will do nothing but sputter, work sporadically and and cut in/out. I've tried everything I can think of to fix the issue, which cost me more than this pump is worth. Still doesn't work. I would save yourself a headache and try a different product. ... show more

  • Perfect for what I needed
Size: T33-12V 3.5GPM 45PSI
I went through 3 other pumps and finally landed with this one. It is amazingly quiet. All I did was hook this up with my existing hoses and power and it worked right out of the gate. I was amazed at how quiet is is and powerful. I am using the default settings for GMP and it works for me. I have this hooked up to a 5 gallon water jug, that I put in fruit punch mix and I am now utilizing my keg fridge. So no more beer, just fruit punch. And this pump pushes out at a perfect speed and pressure. I love this and as for longevity, we shall see. |So far its been 3 months and going strong. ... show more

  • Reliable Water Flow with YOUNGTREE Water Diaphragm Pump
Size: T33-12V 3.5GPM 45PSI
Last season, I installed the YOUNGTREE Water Diaphragm Pump, a 12 Volt DC unit capable of 3.5 GPM at 45 PSI, and it performed flawlessly throughout. This self-priming pump delivers consistent water pressure on demand, enhancing the efficiency of my water system. Its performance so far gives me confidence that it will continue to operate effectively in the upcoming season. I'll provide an update if anything changes, but as of now, I expect it to remain in top condition. This pump is an excellent choice for anyone needing a reliable and powerful water supply solution. ... show more
