"Put together a transfer pump for adding fresh water to my RV when doing extended. Boondocking... Works very well tho a little slower than expected but the good thing is. I no longer have to fight those big water jugs up and dump them in... Worth every penny!"
"The fresh water pump in our RV finally went , and I picked this up as a replacement; when I saw the size after it came I was somewhat skeptical of how well it would perform, since it was much smaller than the original pump; but I installed it, ( it installed very easily with a few pvc adapters form the hardware store) and much to my surprise, even though this pump has a lower listed flow rate than the old pump, it has equal or better water pressure, it's quieter, and it runs less often; I will be picking up another to use as a spare for the road...."
"The pressure was just right for my camper's small faucet."
"best value for the one-spot water need in an RV camper, small and compact."

"Amazon, or supplier, filled the order immediately so even though I did not need the pump after all, I gave a 5-star rating because the order was filled immediately with same product as was in the boat."
"Purchased this and a DC power supply and a roll of wire to use as a automatic pool cover pump!!!!!"
"For our installation, we use the float, so I clip the brown wire with the "plus" sign sticker, clamp a ring to the two other ends, and then connect it up to the boat's battery."
"Installed Friday night and was out on the boat all day sunday with out ever having to turn pump on with switch."
"When setting up the connections with wiring I can't seem to have a positive connection with this pump."
"I thought I was doing something wrong so I had the local shop do the installation."
"Sorry, but it's junk."

Two hoses and a 12-volt power supply are required, so using this Flojet 18555-000A, Portable RV Waste Pump is not as simple as emptying our tanks at a dump station."
"This device made boondocking at my brother's house worthwhile."
"Pointer, get some extra wire because the 6’ included obviously won’t reach the battery / power source."
