Plumbing Supplies
Guides on the tools, fittings, sealants and small parts a homeowner needs to finish a plumbing job properly. You will find what belongs in a basic home kit and what can be skipped, plus the comparisons that settle recurring questions: Teflon tape against pipe dope against plumber’s putty against silicone, brass against poly PEX fittings, when purple primer is required, and what fitting labels such as MIP, FIP and NPT mean. Buying guides cover wrenches, pipe cutters, crimp tools, torches, insulation, washing machine hoses and outdoor faucet covers, and separate cost articles explain what hiring a plumber involves instead.
Picks come from hands-on trade experience: the brands a licensed plumber keeps on the truck because they hold up, checked against manufacturer specifications and code. No manufacturer pays to be listed. Some links here are affiliate links, mostly to Amazon; if you buy through one the site may earn a commission at no extra cost to you.
