@twinhomeexperts: Most plumbers will disagree with me on this… but after 30+ years in plumbing, I’ve seen these two water heater connections cause MASSIVE corrosion, low water pressure, rust buildup, and leaks over and over again. ❌ Hard piping directly with copper ❌ Cheap dielectric unions that clog internally Instead, I prefer using quality brass unions and brass nipples for a cleaner, longer-lasting connection. Not all plumbing failures happen overnight… some slowly destroy your system for years before you notice. #plumbing #waterheater #plumber #homerepair #DIY

Everything from home depot and Lowe's is cheap material. Always buy from a real plumbing supply store

I always use a brass nipple to the water heater, then to the hard pipe. never rots. dielectric fittings suck!
