Reliable 12V Self-Priming Pump for RV and Marine Use

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.

Best waterpump on the market

This is a top of the line water pump for rv's and is factory installed on a lot of upper end rv's. The quality is second to none and a 4 year warranty speaks for itself. Update, we have used this pump now and it's working like a dream, so quiet and pressure is perfect. We live in our class A motorhome and we can't hear it run

Best RV water pump, water flow and very quite!

Why did you pick this product vs others?:Finally! After 6yrs and 35,000 miles a water pump that is extremely quite! This was my 4th pump, all others functioned fine but the thumping/vibrating was just not acceptable. Easy to install, fit perfectly in the existing application. Everything needed was included in the box. Only question, will it last?!

I previously gave a one star review on this pump due to air in the water line. Had a installation issue with a air leak in the water intake side repaired and working great. Sorry for the bad review.

Dummy proof

Hooks up easy pumps steady. This is my second one. The first one is still going strong after 2 years but decided to get another as a spare.

works great

I am sold on this product, i ordered three different pumps and none worked and did not do the job. This is the only pump that works on my 2009 open range 33rl . I will not buy any other again

Died within 2 weeks of use

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
