It was the perfect choice for my small truck/camper system. The plastic construction is robust and feels to be well manufactured. Installation is very simple: attach 3/8" ID hose to barb connectors with hose clamps and connect the positive and negative wires to your 12V source via a switch or relay. Water pressure was very good when running directly at full flow, but when running with partially open valve (restricted flow), the pump's pressure switch causes rapid on/off cycles. I chose to couple the pump with a 0.75L accumulator to eliminate this chatter and reduce electrical/mechanical wear. Very happy with the overall performance of this water pump.

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.
