Pump is very noisy

Bypass valve failed after six months, they will not replace just the part. Customer service is horrible, I just need the valve, they want me to send the whole system back then they will send me a whole replacement. Really don't feel like uninstalling and then reinstall the whole system when I just need the bypass valve. Their customer support makes no sense whatsoever. They want a video of me showing that the valve failed and that there is hot water coming from my cold tap, last time I checked hot and cold water look the same on video. Save yourself the headache, avoid vevor.

The under-sink diverter is noisy — I can clearly hear water running, and it’s very noticeable. Other than that, the pump works fine. The bigger issue is the lack of instructions. That’s a serious problem for installation and setup. Also, if you’re using standard U.S. tanks, you’ll likely need to buy adapters to fit the threads, which can cost another ~$30. Returns are not easy or convenient either. I won’t buy from Vevor again for that reason. If you want to operate like a major online retailer, the return process should be straightforward — customers shouldn’t have to go through customer service just to return an item.

I purchased a Viboar 12PBG-18 hot water recirculating pump and have been extremely disappointed with its performance and reliability. The pump was advertised as a solution for improving hot water delivery, but my experience has been the exact opposite. The unit is noisy, produces noticeable vibration, and does not circulate water consistently. Even after proper installation and troubleshooting, the hot water delivery was far less effective than expected. The overall build quality appears cheap. The housing, fittings, and electrical components do not inspire confidence for long-term use. I am concerned about the durability of the pump, especially when compared to better-known brands in the industry. Another major frustration is the lack of clear documentation and technical support. The instructions are minimal and leave too much room for guesswork during installation and setup. When a product requires troubleshooting, detailed documentation becomes critical, and this pump falls short. For something as important as a hot water recirculation system, reliability is the primary requirement. Unfortunately, the Viboar 12PBG-18 did not meet that standard in my experience. I would not purchase this pump again and cannot recommend it to anyone looking for a dependable long-term solution. Spending more money on a higher-quality brand would likely save considerable frustration in the future.

The pump does not work as described, no response to my questions within first 48 hours, after repeated complaint, they finally give me stupid response which did not solve the problem. I realized it's the defect of product and therefore submitted request for return twice already, but the tickets were closed twice without any explanation. Feel ashamed of Vevor's terrible service, I never had such terrible purchasing experience anywhere. Do not buy from them!

Never received either item - their shipping is so convoluted that the customer doesn't know how an item will be shipped (snail mail, UPS, FedEx, etc) so if you have one address for US (snail) Mail and another for parcel services, you don't know which to use and there's no way to specify if in the order process. Sucks because some Vevor stuff that's made it here thru their maze is of reasonable quality. Oh well...

Worst directions possible. If VEVOR makes installation possible this could be a great value. Like many other things from VEVOR, this is not one of

Would not recommend buying this pump. The pump only last me two months before it started leaking water from the inside. I should have stuck with my saying, "You get what you pay for".
