Comet 12V

Expensive, but appears to be high quality, and the size allows it to be used in a small-mouthed water jug. Just what I needed for my camper van. Also MUCH quieter than the pressure-system pumps that are not submersible. And this type does not keep the water line pressurized except when switched on; a pressure activated system is just asking for a leak when you are not watching it. I wired it to a 12v on/off switch, so I can leave the tap open and just turn it on with a switch. I tried one of the 12v wired taps, but liked the quality of a simple cold water tap with this pump attached with a simple silicone line to the tap. When boondocking, simple is better.

The pump is small for the power it puts out. We used it for a very small sink on our boat and it is perfect. The polarity on the wires really does not matter. I dropped in a tank of water in our sink at home and used a 9-volt battery to test with and it pumped water the same direction no matter which way i connected the wires. Great value for the money and it works great.

Fantastic submersible pump. So compact yet powerful enough for a great camp shower.

Nice to have running water in the Hotel Prius. Pumps out out of a 7 gal container from under my bed platform. Used for kitchen, bath, shower..even bidet. Not much of a shower, granted, but for most practical purposes one could not expect more from a pump. Remote switch on wire with a long enough tube fitted with one of those shower on/off push button shutoffs works great. I fill tank by using a quick connect attached to the shower valve which is 1/2" FIP that I hook to a garden hose and run at moderate volume while refilling. No need to take my tank out and lift 45 lbs of water. If you don't push it too hard it appears when refilling the tank through the pump line that running the water back through the pump itself has done no harm..yet. No doubt it spins the little impeller ....but still works fine. After I use the pump and turn off switch I let the water in the hose drain back in tank to avoid any spills. Three years of occasional camping use and it has held up fine.

After 4 months of full-time use in my van, I think this pump is great. I’ve frozen it a few times and had no problems. I use a 3 amp fuse and when I tried to turn the pump on while frozen, the fuse blew, appropriately. Depending on your faucet, add an in-line check valve so the water doesn’t drain from the line back into the tank each time you turn off the water. I use a 12 volt faucet with a little toggle switch and I restrict the flow in the line with no problems from the pump, otherwise the pressure is too much for my application.

It seems like it's well made and doesn't smell like chinesium. However, for the price, I'm not very impressed. The output is very weak. I hooked this up to a 5 gallon water jug and attached a 2.5GPM RV shower head to it. It doesn't come close to satisfying 2.5GPM. Nevertheless, I think it will work for what I need. I don't plan to shower with it...just to wash my hands and what not when I'm on a fishing trip or something along those lines.

Our self priming diaphragm pump was so loud in our van we had to replace it. This submersible pump is so quiet we can hardly tell it's on. It's whisper quiet. We did give up a little flow but that's OK, we no longer cringe when the pump is on. Would definitely recommend.

Small in size. Worked good and lifted water 16’ from a well casing 4” in diameter. Easy to install and worked efficiently on 12 volts. Mike
