How To Lubricate A Pvc Ball Valve
Lubricating your PVC ball valve is an important part of its upkeep. By keeping it lubricated, you can help it to last longer and avoid potential damage. In this article, we'll show you how to properly lubricate a PVC ball valve so that it continues to work properly for years to come.Turn off the water to the valveLocate the PVC ball valve handle. This is the knob that you turn to open and close the valve.To lubricate a PVC ball valve, you'll need to first turn off the water to the valve. Then, locate the PVC ball valve handle. This is the knob that you turn to open and close the valve. Once you've found the handle, unscrew it from the valve. This will expose the inner workings of the valve. You'll see a small ball inside the valve.This is what controls the flow of water through the valve. To lubricate the valve, simply apply a few drops of lubricant to this ball. You can use any type of lubricant, but we recommend using a silicone-based lubricant for best results. Once you've applied t
