SEAFLO33 Series 12V DC RV/Camper/Boat/Off-Grid Fresh Water Pressure Pump –12V, 3.0 GPM, 45 PSI, On Demand Self-Priming, Built-In Pressure Switch - NSF, CE & Rohs Certified, UL Listed, 4-Year Warranty

This pump is a dependable choice for boosting fresh water systems in RVs and boats. I installed it in my camper, and it delivers steady water flow (~3 GPM) at 45 PSI, enough for normal running faucets and showers.The pump self-primes quickly, so I didn’t have to worry about air locks or manual filling. It starts running as soon as I open the tap and stops cleanly when I turn it off. I like that it works on 12V DC, so it matches well with typical vehicle systems.It’s built solid, with robust housing that handles regular use and won’t leak. It runs quietly and fits in tight spaces. The included fittings make it easy to connect to standard hoses.One small thing: it draws a fair amount of current, so it’s worth ensuring your battery or shore power can supply it. Also, it has a short auto-run time, so avoid running it dry.Overall, the SEAFLO 3.0 GPM 45 PSI Pump is a solid and practical solution for mobile water systems. It provides consistent flow, reliable self-priming, and fits well in RV or marine setups.

These are the best pumps for marine use. I use these as a live well oh,p on a timer. They last a long time as long as you keep the clean.

We have an older (1991) motorhome that still had its original water pump. Since we bought the RV when it was already 27 years old, we didn't think much about how noisy the old pump was when it ran and how much it vibrated all the pipes. It got so bad that it actually cracked a PEX connector in my plumbing from all the vibration. Fortunately we caught it before too much of a flood. That was the incentive to look for a better pump in hopes of getting one that would be quieter and not vibrate the whole RV when you flushed the toilet.After doing quite a bit of research and looking at reviews we chose the SeaFlo pump. It's a good name brand and had a reputation of being relatively quiet. We couldn't be happier with it. We installed it with a SeaFlo Accumulator tank (0.75 l) and after hooking it up and wiring it up I went ahead and turned it on. At first I thought it wasn't working because I didn't hear ANYTHING! However the water started coming out the faucet and when I got closer to it or put my hand on the pump it was clear it was in fact working, but was living up to its QUIET reputation.I highly recommend this pump. You could spend less on a cheap knockoff import unit, but seriously is it really worth saving a few dollars on something that probably won't last and may be rather noisy when you can get the best with SeaFlo.And no, I'm not paid by SeaFlo to do this review, I'm just incredibly impressed with the quality and want to share that.

I purchased at the end of Dec 2024, and unfortunately then end of May 2025 it gave out completely. When it worked it was really great, I'm thinking it may have been a defective item or something as the other reviews are mostly positive. When I reached out for product support, the resolution occurred within one week, support was quick to answer my questions and offer multiple solutions for me to choose from.

Very easy to install and works AMAZING, I live off grid and needed a way to pump water from my storage tank to the tiny home and to outdoor shower. I previously had purchased a well pump for 3x the price of this and it never performed correctly. Pressure is good it can run dry and not damage which is a huge plus,

replaced my previous 1.3 gpm unit and this was with higher flow and pressure is quieter. you almost don't even notice its running. great upgrade to my camping setup!

I've had it hooked up for two to three weeks. I don't even use it that much. I was taking a shower yesterday. It wasn't on for very long at all because I turn the shower on and off with the shower head button on/off switch. All of a sudden, there's no pressure. So I have to get out all soapy go outside in the back of the RV and go check the pump, and it's super hot. After about an hour it pumps about two pounds of pressure. I mean basically zero pressure If the Shurflo company can see this, can you guys send me another one?I have another larger your flow one coming. I hope that one doesn't break down as well. I wouldn't recommend this pump at all. I don't even know how to try to send it back. I don't know who to contact. I bought it in March, but I didn't hook it up until about three weeks ago. All I use the pump for is a little bit of kitchen water and a shower a couple of times a week. Like I said, I turn the water off while soaping, so the pump doesn't work too much; that definitely isn't the problem. Pump isn't any good .Well, I'm screwed. I'm going to try to get hold of the company. I can't even figure out how to do that . It's not just the $50 that I'm out . It's hooking it up it's not so easy. The fittings weren't so great and it wasn't easy to hook up. Maybe If they help me out, I'll change my one-star review. I know things happen, but I need a pump that works. You can't be changing them over and over. I should have just gotten a better one to begin with. Well I'm screwed I don't even know how I'm going to get a pump in there

Works and fits as described
