Really great manual pump
I installed this foot pump in an older Aliner pop up camper that we have. Formerly, I had a noisy electrical pump to bring water from a simple container through a faucet and into a sink that I installed. This camper did not come with a sink or a water system so I created one on a budget. I thought that the convenience of an electric pump would be nice and I didn't want a foot pedal in the way of our small interior. Happily, the foot pedal is not much of a tripping hazard. It's easy to avoid and doesn't stick out as far as I had thought. We haven't had any problems falling over it. We don't often plug in while camping. Preferring to boondock and be off the grid, I didn't think about the amount of power that an electric pump utilized. Our tiny solar system and battery would give out after a day or two in the woods with minimal electrical pump use. This was a bummer while washing dishes, cooking or brushing teeth. Having this foot pump has really made life easier! This manual pump puts out a very strong flow and it produces a stream both on the down pump and also when the foot lever goes back up. Essentially it's double-actioned and you get two spurts of water for every single foot pump. It's also very easy to use. I imagined that it might take some heavy priming with strenuous action prior to any flow but that is not the case. The pedal depresses easily and starts to flow after only 1 or 2 foot pumps if the line is not primed with water already. Once the water line is primed with water it works immediately even after sitting unused for many hours. It's much quieter than a noisy electric pump. I used to cringe when camping near others if I woke up early and wanted to fill a kettle for hot water in the morning. The electric pump we had would rattle and roar at an alarming volume and could be heard from a good distance outside of our camper. No more! This foot pump is terrific. It's low tech, solidly built, easy to install, works quietly and has strong flow rate. It does cost more than an electric pump but it allows for a smaller solar / battery setup which is often a large expense for a DIY camper or van install. Being able to use it without any power at all is a huge perk too. I like the simplicity of this setup. I love not using up my limited battery power. I highly recommend this manual foot pump for a simple kitchen camper setup!

It double pumps
Installed in my sailboat and replaces a TMC brand. I've only used it about 5 times and so far it seems fine. I went with this bcs people commented the rubber lasts longer. An important point that I did not realize when ordering. My old TMC only pumped H2O on the down stroke. This brand pumps water on both the down and up-stroke of the foot pedal. I suppose that is efficient but personally I'd prefer if it did not do that as it increases your H2O consumption a bit. This also causes the H2O pressure to be lower on the up-stroke. But it's fine as I'm not crossing an ocean right now. Plug and play direct replacement, 5 minute installation.

Low capacity, but does the job. Slowly.
Had a reason to use this pump two weeks after it arrived, when our power failed and our water-powered basement sump pump couldn't keep up during a storm. The flow is low, maybe 10-12 oz per stroke, with a 10-ft head (in our case, pumped up one flight of stairs to a 1st floor bathroom drain). Neither port is marked as input or output and there were no instructions, but I guessed and it worked. I'm wondering if it works either way, but don't care enough to experiment. I screwed it to a 5" x 24" piece of 1" oak, and we started by putting one foot on the end of the board and the other pushing down on the foot pedal. We eventually improved the setup by sliding the end of the board under our washer, which removed the need to balance on the board on one foot and made the job much easier. Obviously if you're using this in a boat, you just screw it to the floor. The biggest complaint about this thing is the recovery time after each stroke. Because the piston is pulling a vacuum against the resistance of the water, it takes about 3 seconds to return to the up position fully. So no matter how motivated YOU are, you won't be moving more than 10-12 oz every 3 seconds. This was enough for our needs during the storm, but you'll have to evaluate it for your situation. If you were in a boat taking on water, you'd never move enough water to make a difference. This is the pump you'd use AFTER the storm quits and you're just trying to dry things up.

Works well on our sailboat
It easily fit in the old slot for the broken pump on our sailboat. Works well.

Poor version of the original workhorse
My old Whale Gusher is a workhorse of a pump. My 2 Whales have served me well for 30 years(with occasional rebuilds). They do eventually crack around the mounting holes in the plastic. When I upgraded my drinking water system, I decided to treat the boat to this brand new pump. I did not know the design had been changed. It is a low quality pump. From brand new, the pump housing plastic outer shells are deformed where the screws hold the halves together. The old pumps had much thicker housings that have ZERO deformation after 30 years. The new pump halves are assembled using sheet metal screws- they MIGHT survive one rebuilding without stripping (if they don't crack first). By comparison, the old pumps were assembled with brass machine screws. Worst of all, the new pump gives the water a terrible taste- NOT suitable for drinking water or even brushing teeth. I flushed the new pump with sudsy dish liquid water, rinsed with gallons of tap water. When that didn't help, I soaked it for 5 days in vinegar water, more dish liquid then tap water rinse. After using the pump (for dish washing only) for a whole summer, the water from the pump is still unfit to drink. Stay away from this product. Makes me suspicious of buying any new Whale products.
