I agree with using distilled water. I just thought it was interesting that Trojan engineer told that tap water is OK to use in there Flow-Rite watering system. Then again, they are in the business of selling batteries. Below is from there web page.
Hand Pump Supply – The hand pump water supply is perfect for the customer who has 1 or 2 golf cars and would like to use distilled water. To operate simply connect the hand pump to the HydroLink™ Watering System and place the other end in a gallon of distilled water. Begin to fill by squeezing the pump. When all of your Trojan batteries are filled the bulb will become firm, not allowing you to add any more water.
Regulated Hose Supply – Flow-Rite’s most popular water supply, the Regulated Hose Supply, provides an inexpensive option to pump operated units yet and allows for fast filling. Installation couldn’t be easier, simply attach to any garden hose bib.
Deionized Water Supply – Maximizes battery life by removing dissolved solids that are present in tap water and can lead to shortened battery life. Economical, the separate bed deionizer uses an ion exchange cartridge filled with non-toxic synthetic resins to remove impurities from you tap water before it enters the battery.
