Installing new faucets or plumbing? Replacing the O-rings in a leaky fixture? As homes begin to age, plumbing repairs and replacement are to be expected. Things like existing valve stems are removed for new parts and new fixtures are put in place. You'll soon find things go in easier, and work much better, if you add a dab or two of lubrication on all threads, joints and packing. But, as you make repairs or replace with new parts, you need to know that all lubricant is not created equal with regard to plumbing. While lubricating plumbing parts makes installation fast, only one lubricant will last and last -- "plumber's grease." It is designed to withstand high temperatures -- up to 350 degrees. While others liquefy, break down and wash out from the repeated heat of steam and hot water, plumber's grease doesn't. It not only makes plumbing go fast it's the one grease that is sure to last, as well. Ask for it. And that's the On The House tip for today.
