installing bwt watering system


Using a single point watering system can save lots of time and effort in maintaining flooded lead acid battery packs. Most golf car and RV owners know that after charging their battery packs they will have to open up the battery compartment in the vehicle, check each battery cell, and fill each one with a precise amount of water.

While watering is a necessary step, making the process simpler and faster can be accomplished by using a single point battery watering system. Complete systems like those from BWT, are a popular choice for many golf car and RV owners because they feature a visible indicator that shows if the battery cell is low on water, and prevents over-filling.

Installing a watering system is easy and over time, can save money by dramatically cutting down on maintenance time, especially if you’re maintaining a fleet. The basic steps include removing the battery cell covers and replacing them with the float-caps provided in the kit. Once all the caps are on each of the battery cells, the hose is trimmed and attached to each of the caps, and routed so that filling can be accomplished near the center of your battery pack.

Most kits come with a gravity feed water tank, or a siphon hose that can be inserted into a bottle of distilled water. It’s also important to remember that after installing a single point watering system, that you only add water after the batteries have been charged.

Although it’s much faster and easier to water flooded lead acid batteries after they’ve been charged, it’s also important to realize that proper watering will extend the service life and performance of the batteries.

bwt single point system

A complete single point watering system like this one from BWT comes ready to assemble.

 

BWT valve/cap

Each battery cap covers one cell and includes a flow-nozzle and float that closes off the incoming water once the cell is properly filled.

 

 

BWT valve cap level indicator

As the float comes up, an indicator window makes it easy to see if the battery cell is filled to the precise level.

 

 

removing battery vent caps

The first step in installing a single point watering system is to remove the vent caps on all of the batteries. Make sure you’re using proper safety equipment and are performing this in a well ventilated area.

 

 

BWT cell cap

The BWT caps simply press and snap into place over each battery cell opening.

 

 

Install hose to bwt cap

Measure and trim the water hose so that the caps are connected.

 

 

connect bwt caps with hose

Here you can see how each battery has its caps in place and that they are connected with a small section of hose.

 

 

connecting battery cells

Depending on how many batteries are in your pack, follow the instructions to measure and trim the hose to properly route the flow of water.

center fill hose

The fill hose is attached to a T-connector that will flow water to both sides of this battery pack.

 

 

bwt center fill hose connected

Here you can see how the filler hose is attached to the center of the pack and how the water fill flow from the center out to each battery cell.

 

 

bwt end flow nozzles plugged

The flow nozzles on the valve caps at the farthest end of the battery pack are capped to prevent water from spilling out during filling.
