Lippert Components Flow Max 12V RV Water Pump, 3.0 GPM, 50 PSI, 9.5 Max Amp, Self-Priming, Screen Filter Included - 689052

Much quieter than Shuflo, exact replacement, all dimensions identical

The 15yo Shurflo pump in my RV stopped holding pressure. I probably could have serviced the valve but decided to replace the pump since I had to take half the RV apart to get to the pump. A few notes on pump replacements in general and on this specific pump. * The Amazon product description says that you might receive one of two different model numbers, but “they are the same”. Except the amps are different per the literature. At any rate, you don’t know what you are getting until you have it in your hand and then can determine the proper circuit and fuse size. In my case I had to go up a fuse size from original pump. Wire size was fine. * The existing pump connected to the water system via barb fittings with hose clamps. I had to cut these off as they wouldn’t come off the existing fittings, the hose having become stiff. The new fittings on the new pump were slightly smaller, so they actually didn’t make a water tight seal on the high pressure side unless I really cranked down the hose clamp. * The new pump seems to operate quietly and reliably, and holds pressure over night when off. * I learned through this process that most of the pump noise actually comes from the waterline on the high pressure side pulsing and flexing with the pump and whacking into the floor or interior parting in the compartment it is in. The solution is not to clamp it down but to let it flex and I put foam pipe insulation around it to deaden the sound and absorb the hits. Made a huge difference in noise. No complaints about the new pump, seems solid, weighs more than the original, performs as expected. The included fittings were what was needed (though 90 degree would have been helpful).

Precio razonable para el uso

I had a working pump in the RV that worked. It worked pretty good, or so I thought. I was reading all the reviews and everyone indicated there was a performance gain with this new pump, and they also said it was so quiet. I thought, "yea, I wonder what quiet really means". But I decided to order the pump as I noticed it cam with a neat little pre-filter and thought that would be a good addition anyways. I did not expect any massive gains with this upgrade. I did pre-wire better supply while waiting for this order. So when I did get the new pump in, it was a 5 minute install. Fired it up, and .... HOLY CRAP. This thing pumps so quick, there are no pulses in the water, and it SOOOO quiet compared to my last pump. Under a cushion bench, I can barely hear the thing. Way better than a high pitch whine/pulse sound grinding away. This pump is only 10 % of my original noise from the other pump. OK, so, now I am super glad that I did upgrade. The RV toilet flushes way better. I think failures on RV toilets are due to lack of water flow, as they cant properly keep the valves clean. So having this new pump really will make a difference. Not knowing about longevity is a concern now, as I do hope I get years out of this pump. Its just too awesome. I'd buy another one in a heart beat.

I powered this 12V pump using an old computer ATX power supply and it worked!!! I connected the pump to my rain barrel and I found no difference on water pressure compared to my garden hose on a regular household faucet, it is so strong. I tested the water pressure, see photo? It has 50 PSI, amazing! Oh yes, it automatically stops at 50 PSI and the pump kicked in when I started to water my plants. The pump has absolutely solid built and it's extremely quiet. I mounted it on the wall in the garage, you don't have to put the pump lower than your water source because according to the manual, it has 6 feet vertical prime. The only complain I had was the connector, it supposed to be PEX. However I had hard time fitting it on my existing 1/2" PEX tube. I compare to the brass PEX connectors I have, it seems the one comes with the pump is slightly bigger. Maybe even PEX has different standard, I don't know. Anyways, I used adjustable steel clamp on rubber hose to solve the problem, no big deal. Overall, you pay for what you get. The price is high, but it performs way beyond my expectation. Love it.
