Flow-Rite Pro-Fill RV Battery Watering System Description

Water levels in lead acid batteries must be checked on a regular basis - a minimum of every 4 to 6 weeks; more in some climates. Improper water levels will shorten battery life and result in poor performance of batteries, equipment, and battery chargers. Hard to reach batteries are just as easy to fill as batteries on a workbench. Several batteries can be filled safely and simultaneously from a single remote position without ever having to touch a battery or remove a cap. Pro-Fill’s automatic control valves ensure each cell is closed when the precise level is reached.

Requires squeeze bulb kit. (Sold separately)

Not a drop of spilled water
Wish my batteries were maintenance free but since that isn't the case, this setup is the answer. Even if I have a battery on a work bench with plenty of access and light, I would always spill/make a mess and inevitably, white corrosion would follow. Given the location of my coach batteries and all the cables routed in the way, my first thought was that I had to replace the batteries with maintenance free but I decided to try this setup first, Cheaper and easier than replacing the batteries.
Installed easily. All replacement cell caps were good and tight fitting with a positive "click" when totally tightened. One cell was very tight and I was afraid that I might break the new cap getting it in but I just put more effort on it and it finally twisted in place. All connections worked as they should. Was kind of miffed that you had to purchase the pump separately but not a big deal. My setup is only on two 6V batteries but pump worked. First time I added about a cup of distilled water to both and bulb became noticeably firm. Time will tell how durable they are. I feel good about having them.

have to have
I sold my other MH and I wanted to keep these and put them on my new MH but I forgot. These are a must to have as there are a God's blessing when filling he batteries with water. Just connect the rubber hose and pump in water as needed. The shipping was supper also.

Works great!
This product has made my life SO MUCH easier. Seemed pricey but makes maintaining our battery bank a snap. The batteries will last longer and more than make up for the purchase.
