  • Throw away those hand pumps
This thing is super fast, hook it to your existing watering system and sit it up high and let gravity do the work, filled up my golf cart batteries in less than a minute.

  • It works on gravity. How can it not work?
Works pretty good

  • great option for forklift batteries
Great affordable option for adding water to my forklift batteries. The flow wheel makes it easy to know when they are full and no more water is flowing into the batteries. I should have bought this earlier. adding the correct amount of water has helped my battery life and brought them back to life!

  • Just Right!
I used it today and it was perfect!! WOW so much easier than a manual hand pump! I use it for my golf cart and I'll bet I'll be more inclined to keep the water level up because it is so easy and I am a kind of lazy old guy! The only fault is where the water comes out of the tank. I wished it was closer to the bottom of the tank, but that's a really minor fault and easy to work around. Highly recommend ... show more

  • portable water supply for stored cart.
Priming the line is definitely an advantage. Fill is very slow if line is not filled with water to start. Once the line is filled with water connecting the unit to the cart fill line will give good flow and the flow indicator works. Without priming the flow is just a trickle and the flow indicator will not turn. Since I am a snowbird my Northern cart is garaged all winter. I also shut off my house water to prevent frozen or broken pipes. This tank is necessary to add water to the cart which remains on the charger while I am gone. ... show more

  • Good way to add water
Held the water without leaking

  • Easy to use
Connected to the battery cover system and it works like a charm. No lifting gallon jugs to fill. Fill the tank, put it on a shelf near your cart, and fill the batteries quickly. There’s a pressure valve that shuts the flow off when they are full. Worth the money

  • Easy Flow
This gravity feed water system with correct fitting supplied works great. 2 gallons of distilled water in the container and set it on the roof and watch it flow Little wheel lets you know when there full. With no mess
