Customer Reviews for VEVOR Water Diaphragm Pump, 20.8 LPM Flow, 4.8 bar Rated Pressure (2.8-6.9 bar Adjustable), 12.7 mm MNPT Self Priming Sprayer Pump with Pressure Switch for RV Camper Marine Boat Lawn, FCC Certified

Very effective pump, does everything promised. Only used it a couple of times so can't speak to longevity yet but so far quite impressed.

Great!

This is a great water pump. Worked perfectly

it uses a classic thermal-current fuse, the one that degrades each time it trips, and they place it near the brushes, where the thermal trip should NEVER go, inside teh motor body with bolts of materials that are GUARANTEED to gall in the body, and heads that strip out when you even think of opening to replace the useless thermal trip with a more reliable/replaceable option if used at 60-70psi as you might for an RV potable water supply this may last a long time, but it says it can be turned up to 100psi, and one would expect that means it NEVER fails to keep doing that for AT LEAST 6 months with a few minutes a day, not so, I hope manufacturers stop EVER using those thermal-current fuses inside motors EVER AGAIN, they ALWAYS fail prematurely and often that causes additional damage to other parts otherwise a great pump, does the job, stays cool, quiet, and full featured, just terrible industry-standard protected motor design(better to simply have no protection at all like that)

It is doing what we need it to do! Thanks!

So far so good, time will tell. But I don't see a reason to buy the more expensive popular pumps over this one. Fairly quite and going from a shurflo 3 gpm to this is Def a little more volume.

Looks well made, haven't used it yet

It works great but only lasted 3 days they are sending me a replacement one hopefully it works better

I haven't installed this yet. I'm in the process of refitting a sailboat. This will be the water pump for the fresh water system.

20 March 2024 I temporarily installed my pump yesterday. The pump, to the best of my knowledge worked continuously for three hours and twenty minutes (3 hrs 20 mins). At the end of that continuous period the pump was hot but still pumping water normally. Since I propose to use the pump one hour on and two hours off during daylight hours the performance yesterday is satisfactory to me. The pump seems to be pumping just over 4 GPM. On Friday/Saturday I propose to use a five gallon container and conduct an exact measurement. Will update thereafter. I will provide periodic updates when the pump is installed permanently. I will update my Star Rating after some permanent use.
