The hoses did not screw onto my heater fully as the fittings were too tightly made. They only went on part way before they stopped turning (causing leaks). I had to buy separate washing machine hoses from the hardware store and they fit fine. The pump worked well after that.

My first disappointment from Vevor. The pump worked good ! the hoses are garbage, could not get them to stop leaking. I tried tightening them so hard that it damaged the threads on one of the flush valves! I ended up wrapping the connections with rags to make them usable. I will need to buy more hoses before using it again which makes it cheaper to just buy a pump from a local supplier.

Edit: My review remains unchanged below, but I have increased rating by 1 star due to Vevor's good customer service dealing with my issue. I've purchased quite a few VEVOR products over the years and have generally been very happy with their quality and value. Unfortunately, this flushing kit was a disappointment. I purchased it to flush my Navien tankless water heater. I could have bought a pump separately and used my own hoses and bucket, but I liked the convenience of having everything needed for the job in one kit that I could store with the water heater for future maintenance. The pump itself worked well once I got it primed. It provided a strong, consistent flow throughout the flushing process. Priming was a little frustrating with everything connected, but I eventually figured out a way to get it going. The hoses were another story. Both leaked at the connections, and I had to add extra rubber washers to get them to seal properly. They're also quite stiff, and the clear outer coating on both hoses was already separating from the hose material. Not exactly what I expected from a brand I've had good experiences with. The included descaling powder was equally disappointing. The directions were so poorly written and confusing that I couldn't confidently determine how much to mix with the water for flushing a tankless heater. I even tried getting help from ChatGPT to decipher the instructions, and its response was, "Those are some terrible instructions!" When even AI can't make sense of the directions, you know there's a problem. Rather than risk using the wrong concentration, I set it aside and went out and purchased vinegar to complete the job. In the end, the kit did get the job done, but mostly because the pump worked well. At around $80, I expected better quality hoses and a descaling product with usable instructions. I paid extra for the convenience of a complete kit, and unfortunately, that's exactly where this product fell short.

Purchased so that we could flush our water heater. Hoses were cheap and faulty. We had to go and purchase others as they leaked at bib juncture.

Hoses did not work on John Wood tankless heater. Would not seal to tank valves. Poor instructions for non do it yourselfer.

it works ok. However, the plating on the fittings on the supplied hoses came off and made a mess. The plating ended up in the bucket and also plugged up the pump. suggest throwing them away and purchasing SS hoses with SS fittings. I was using vinegar

I bought another kit before this one and gave it 5 stars because it was a quality product at a low price. Unfortunately, the second kit was rated 3 stars because it had one damaged hose. I got another one from Home Depot just so I could get the job done for convenience sake, although I hope they would have replaced it and that I wouldn't have had to jump through too many hoops. Next time I will have to test how their coverage is on a product that arrives damaged when shipped. Hopefully there won't be a next time though.

Promptly recd my kit approx 2 weeks ago. Service is always great. The instruction book is lacking but its not to hard to figure out. Unfortunately when I hooked the unit up I was only able to run for a few minutes. The hose connections were leaking so bad where they are crimped, they were spraying the solution all over me, shelves, and my epoxy garage floor. I retightened twice but no help. I gave up and rinsed my floor with the water hose hoping the acidic solution causes no damage. These floors arent cheap.

purchased this in October 2026 shipped ans arrived on time hoses leaked at crimped fitting area and had to buy new ones from box store used it to clean a Rheem tankless unit

Mad piece of shit! Hoses, although constructed well are not designed for the North American market. The threads might be three-quarter NPT, but they are not hose bib thread. They don’t even thread onto the pump itself. Before said they’d send me a new one or I can have a refund. I had to cut the wire off of a brand new pump that worked fine to throw it all in garbage because they didn’t want it back.
