Re: Hayward Tyler snifting valve

Friction is probably the most important thing to get rid of. Some people even take the shields off the ball races, and wash out the grease, replacing it with a very small amount of very light grade oil. It might be worth using a lubricant on the gears that is Teflon/PTFE based, use absolute minimum.
