Will be assembling my new Intex Sand & Salt water combo filter tomorrow. I learned not to use petroleum jelly on these types of systems. Went to HD and they were out of Super Lube - a synthetic lubricant - in their tools section. They were out of most of their lubricants. Went to plumbing aisle hoping to find some options but there was only a small tube of plumbers grease. Do folks recommend lubricating gaskets on Intex SWG filters or since you might not want any grease leaching into the pool water, just replacing gaskets after every season (or just when necessary)?
