I was helping out a friend who operates a mobile food service concession restaurant for large events ie. Fairs, Festivals, Company Employee appreciation events & so on! His particular units require a powerful flow from 3 sources sometime happening simultaneously! For specifically no other reason other than "Price" I convinced NOT to purchase the tried & true "Shur-Flo" direct identical replacement. VEVOR pump specs were superior to Shur-Flo at every category like Draw distance & height was triple, GPM was way more the original (uncertain exactly the value but significant) with ALL that said. This little pump is still going strong close to a year now! It’s pumped enough water to return Lake Tahoe to its "Hey Day"!…… who knows! Someone could’ve replaced their bilge pump on their cabin cruiser with this VEVOR pump and left the pump on causing the massive lake levels to drop so quickly & drastically! Hey you never know! You too will be surprised I’m certain with this little sucker…. &… pumper! It’s POWER = 10, ease of installment = 9 would have been 10 had "Free Installation" been offered, otherwise multiple connection types were covered including Teflon tape and stainless fittings!!, FORM, FIT, & FUNCTION = 10-again! Features like kick on, & kick off, easily adjustable w/provided Hex key, vibration control mounting plate with mounting hardware included! Overload protection, & wiring hardware to ease installation… QUALITY = 10, It’s no secret I fell in love with the little Orange & Black pump of the future! with cast metal pump housing & steel fittings! PERFORMANCE = VEVOR Pump specs were…(and I’m being completely honest) they were nearly doubled! Suction line distance, & suction Height! Operating pressure range! The GPM Flow rate! Overload protection & super quiet decibe reading within inches of the unit well below ALL comparable brands And "NOW… HERE’S THE RUB"!……. PRICE! Shu-Flo…. Very close to $200 dollars! VEVOR’S PRICE…. If my memory serves me correctly! It was somewhere around $45-$50 maybe $60. I had coupons & rebates or something! Strongly recommend, if you need water in your RV. Or if you enjoy a shower that’s actually showering! It’s your daisy if you do!

Great little pump that I set up for a tankless toilet. It's a little loud at the moment with flexible hoses on each end, so I'll add a pressure tank/accumulator and some insulation at a later date. The teflon tape sent with the pump is horrible. Vevor shouldn't bother sending it. It's an unnecessary blemish on an otherwise great product.

Questions and Answers (85)

On July 22, 2023, someone asked what size the inlet and outlet are, and the answer was 3/4", but they are actually 1/2". However it does come with one 3/4" adapter. My question is, can I buy another adapted and safely run 3/4 on both the inlet and the outlet?
Sorry, the inlet and outlet of this pump itself is a 1/2" external thread, not a 3/4". The additional connector accessories are also a 1/2" internal thread to a 1/2" tower port. There is currently no 3 /4”, we suggest you check locally to see if there are suitable connector accessories.
