SEAFLO 42 Series 12V RV Water Pump, 3.0 GPM 55 PSI, 4-Year Warranty, On-Demand Fresh Water Pressure Pump with Bypass, Self-Priming for RVs, Boats, Marine & Off-Grid Use, UL Listed

Perfect replacement for my OEM pump. Installed it quickly and had it working in no time at all. I feel like this pump is superior to the original as it seems to have better pressure, is quieter and with the SEAFLO accumulation tank added, it runs less frequently. Really happy with this product.

Excellent product. Super quiet, very easy to install, perfect fit for my setup, very well made. It comes with a rubber base to absorb vibrations which makes it quieter than it already is. I’ve been using it daily for about a week now without any issues. My daily use is basically to water my garden which takers about 30 minutes of continuous use and supply a toilet and a sink that are off grid. Suction head of my setup is about 2 feet and the other end head is about 10 feet, no issues at all, pressure is great and the auto shut off works flawlessly. Mine is powered by a small battery bank of about 50amps that is connected to a wind generator so is completely off grid. If you want a quiet, powerful, easy to install, great quality 12 volts pump; look no further this is the one you need!!!

I use this pump as the main pump for a domestic water system at my off grid cabin. It's powered by a 12v battery that is charged by a solar panel, and it pulls water from a 100 gallon agricultural spray tank. It has plenty of flow and pressure for washing dishes or taking a shower, and it puts out fairly steady pressure for a diaphragm pump- I haven't needed to add a surge tank. It's mounted to one of the posts under the floor of the cabin and it's quiet enough to not really be very audible when running. It's survived several seasons of use without noticeable wear and tear. I drain it down every winter and remove the screen and have had no freeze damage. The water it pumps from the tank ranges in temperature from 45 degrees to 90 degrees depending on the season and it doesn't seem to make any difference to the pump.

Works well and very quiet. I have not had any issues with it.

Was install to day! Love it great product!

We purchased our rig in October 2019 and it came with the Shurflo 4008-101-A65 which is common, we have had the trailer about 7 months. We rarely use the fresh water tank and are always connected to city water, two weeks ago, we heard water running and when we went out to look. There was water was coming out of the fresh water tank fill valve. We were connected to city water intake nothing should have been going into the fresh water tank. It was determined that the control valve inside the current pump had failed and we were given a couple suggestions from the dealership to try and get it to reset until we could bring it in for them to look at. Nothing fixed it and the water was flowing into the fresh water tank as if we were connected to the fresh water tank intake. We had a water regulator on the hose and the psi from the source was below what is recommended pressure wise for the water pump. And of course the regular maintenance suggested to maintain clean water lines had been done every time the inline filter was replaced. After some searching and research we found that this is a common problem with the shurflo water pumps.. We were definitely not impressed that a water pump failed 7 months after purchase. Now after talking with friends, and the dealership the SEAFLO 42-Series Water Pressure Diaphragm Pump w/Variable Flow For Reduced Cycling - 12V, 3.0GP was suggested as a great replacement option. Install was quick and easy, the water connections matched up perfectly with the old pump so no new plumbing or rerouting of pipes was needed. The wire connections were an easy swap out and within 30 minutes we were up and running again. I can not believe how quite this pump is, we barely hear it kick on, water flow from the pump is the same if not better than the old pump. Durability is something that will have to be determined after we have this pump for a while.

I don’t typically leave negative reviews, but this could literally be life or death for someone and I feel a responsibility to inform anyone who may be relying on this for potable water, or any situation where the products failure could be catastrophic. Sure it is quiet, inexpensive, good psi, boasting low flow capabilities and an impressive warranty (granted I still needed to install an accumulator tank because mine still cycles, and people have reported they don’t honor their warranty) - but the pressure switch on this has caused catastrophic issues for many people (just search YouTube); as far as draining freshwater tanks out at sea due to melting the plastic water joints (not to mention potentially starting a fire). Well, its not a myth. I’ve pumped maybe 100 gallons simply to test the water system I installed in my sprinter. Worked great, so I thought maybe those people had it in too humid environments for too long and that caused the issue (still shouldn’t happen on a water pump, but ok you get what you pay for). Well, brand new pump… Dry location… Still returnable to Amazon… It seemed to work fine so I took a trip (I’m still on the trip trying to get a new pump sent to me on my way). First night (last night), it started shorting out when it reached pressure, just as it has been cautioned in the videos I have watched. It shorts enough to make an electrical short crackling sound and make the lights in the van flicker while the pump rapidly cycles on and off, but not enough to trip the fuse. Plus it still pumps water… for now… As such, I can certainly understand how if this was out of observable range (acoustically or visually), and not tampering with sensitive lighting dimmers (different circuit, non-isolated, same power source), one would not necessarily know that it’s shorting out until it’s too late and has melted itself, and potentially the connected plumbing (which is how this has unknowingly drained freshwater tanks at sea)… Thankfully I’m still under Amazon’s return window (yes it’s that new), and they will honor the return, otherwise I’d have to deal with the seaflo warranty that they don’t seem to honor (read reviews of them delaying by months, or going MIA, or even going as far as just telling people to just bypass the pressure switch and keep the faulty unit). I decided to buy a higher quality pump for peace of mind. And I’m not even out at sea. But the possibility of a fire? Or suddenly draining the freshwater tank into my van? Perhaps while 5 days out into the desert? Nope. It’s a known issue and simple fix seaflo. You could literally be the cause of someone’s demise for not just fixing this issue. It’s not just inconvenient; it’s potentially someone’s life if they are weeks from land or way off grid. Buyer beware.

My tank sprayer needed a pump so I replaced the pump in my RV with this & moved the rv pump to the sprayer. This pump is amazing. Quite a bit quieter than the stock pump plus with the bypass function it can be adjusted to just trickle out if the faucet but the pump does not short cycle. 20 minute install, very very easy to do. Couldn’t be happier.

Purchased with the pump Seaflow accumulator tank- great combination, very smooth consistent water flow and volumes super low. Fantastic purchase

Excelente!

Muy buen producto ‼️

Ja det är vad jag planerat, för mitt kök på landet, bra tryck och lätt ljud, slutar när kranen stängs. Jag giltig. Carina

Finalmente si può usare di notte, molto silenziosa, facilissima da regolare
