I'll update this review when I actually RECEIVE the product, but currently I'm going on 6 weeks for actual delivery of this. I ordered it May 1 and as of June 9, still no pump. The delivery time period shows sometime between May 28 and June 14 (no PRIME shipping was available when I purchased it - but I see it is NOW...), but every other product I've ever ordered from Amazon with such a broad shipping timeframe still arrives within 2 weeks... With several other reviews on here saying they got theirs quickly, I'm getting concerned my order was lost and I may be out $28... I hope not, but I can only assume they're shipping this from China on a row boat, it encountered a monster storm, sank, had to be retrieved by a submarine, was placed on another row boat, Nigerian pirates commandeered the second row boat and are holding my pump for ransom... You get the idea.I trust it'll be a good product when it does arrive, but I hope the 2014 camping season isn't completely over by the time it does. I need this for my popup trailer now! Two separate orders for LED lightbulbs placed on the same day and given the same broad shipping time period were received several weeks ago. This is getting a bit ridiculous.I'll update this with a review of the product itself when it does arrive. Shipping sucks though. Pay for 2-day shipping. I wish I knew that when I bought it. I may not have time to install this before our second trip. I'm already going to miss out on it for our first trip this year.UPDATE: I was supposed to receive the pump by June 13, but that date came and went. I had little-to-no expectation of receiving a refund for some reason, but contacted the seller and explained the problem. They answered promptly and refunded my money within a couple of days. I went ahead and re-ordered (this time with PRIME shipping) and received the pump yesterday on-time. I will install it in my popup trailer in a couple of days and update the review with the pumps functionality at that time. Great response by the seller though!UPDATE PART 2: I finally got to the install today and found like other buyers that it came with no instructions whatsoever. Power wires are pretty self-explanatory (red is +, black is -), but the inlet/outlet ports weren't even labeled. I connected 3/8" tubing to each side and after a quick test on my popup trailer battery found that left is inlet, right is outlet.Install went smooth and easy. I t'd into the water line for the hand-pump side of my faucet (Leisure Components faucet purchased on Amazon) and plugged into the inlet of the pump. From the outlet I plugged the hose into a t'd connection I installed in the city water hose. Wired it up and tapped into the power wire for my thermostat, grounded to the frame, and I was good to go. I installed a toggle on/off switch so that I can bypass the water pump entirely if need-be for some reason.The pump is a little bit noisy by itself, but once the dinette cushions are back on and particularly if there are some additional items in the space under the dinette seat, it's actually very quiet and muffled. The reviewers who claim it's loud enough to wake up the whole campground are exaggerating a TON. The mounting feet are thick rubber to help dampen the noise and not spread vibrations through the trailer frame, but I cut up an old mouse pad and used that as a buffer between the pump and trailer frame as well to help with that even more.All things said, I'm extremely pleased with the purchase. I can still pump water with the faucet as normal, can plug into city water if available, and can use the water pump itself for those times my family doesn't want to have to pump water from the facet when we're boondock camping. The $30 price tag and free shipping simply can't be beat either. AWESOME product!

I installed this in my 1976 truck camper, and it works well. Be sure to follow the installation instructions and remember it is a weak pump. It won't work/pump unless you have the line open (turn the faucet on) as it can't overcome the air pressure by its little self. The price was right, install was easy, and it is a bit noisy, but not worse than anything I would expect for the size and money. I have it hooked up to a single faucet with a filter on the line, and a little presurized holding tank to help keep pressure up and the pump not working as hard. I'd buy it again.

Used this pump to help in my maple syrup operation. Turned on and off several time during the process with no issues. It has good power too - pushed over 50 gallons of water through a 50 foot hose up a level of stairs in a relatively short time. Plastic barbed pipe ends don't seem all that sturdy, so you have to be careful with that.

Good replacement for my old camper, nice water pressure, and fast, it’s a little noisy but so what!

Only complaint is small and silly -- there's no arrow citing direction of water flow. I futzled around for a while mystfied at all the sound but no pumping. You won't do that, having an IQ higher than mine (which won't be hard to achieve) and will like this pump a lot. Its four rubber mounts make it super-easy to mount in your RV or van (my case.)

Great product

I got this pump twice. The first one came in a regular manufacturer cardboard box but was obviously used since the wires were all twisted up and one of the mount legs was missing. I returned the pump and got a replacement. The replacement was not apparently used (clean wires, nothing missing), but came in a simple plastic bag. Odd. Nonetheless, I hooked the pump up and it worked just fine.I use the pump for a tankless camping shower. After the second use - or a total of about 5 gal of water pumped, the pump started to pump at random. The motor keeps running but it loses suction as if you were running it dry. After a few restarts it would pump again for a gallon or two until it stopped transporting water again. Needless to say, unless you want to finish your camping shower with a bucket of cold water to get the soap off, go spend more money and buy a pump that doesn't get it's motivation from the number of chipmunks passing by.

A+ easy to install
