need some good DIY tips to keep my pipes from acting up

So, last weekend I had a minor plumbing disaster - nothing too crazy, just a leaky faucet that turned into a bigger headache than expected. Got me thinking, though...I really don't know much about keeping my plumbing in decent shape. I mean, I know the basics like not pouring grease down the drain and stuff, but are there any good websites or youtube channels you guys trust for simple plumbing upkeep? Preferably something easy to follow for someone who's, um, not exactly handy around the house.
